Map for india for 30th November event

Two good asteroidal occultations coming up last week of Novembe

2011-11-21T23:36:00.000+05:30

Two good asteroidal occultations coming up last week of November. Those with moderate sized telescope can observe the event. These events have good probability of above Rank 60, so it means that its surely a good shot. 29th Nov one is going quite close to Pune and 30th one is going quite close to delhi. Let's observe and gather data!

On 2011 Nov 29 13:36 UT or 19:06 IST, the 38 km diameter asteroid (193) Ambrosia will occult a 7.3
mag star in the constellation Capricornus for observers along a path across
India. In the case of an occultation, the combined light of the asteroid and the star
will drop by 7.7 mag to 15.0 mag (the magnitude of the asteroid) for at most 1.3
seconds.

On 2011 Nov 30, 14:53 UT or 20:23 IST, the 33 km diameter asteroid (1283) Komsomolia will occult a
6.8 mag star in the constellation Aquarius for observers along a path across
China, India, Arabia. In the case of an occultation, the combined light of the asteroid and the star
will drop by 8.5 mag to 15.3 mag (the magnitude of the asteroid) for at most 1.9
seconds.

Details will soon be updated.

Item	Meaning
Day	The day of the event. Occult searches for events on the basis of geocentric conjunctions that occur within a 24hr - with that period starting at the UT indicated in the date selection box. Users should ensure that the period starts near the middle of their day.
Time	The predicted UTC, in hours, mins and secs.
P	The Phase of the event. Values are: D - disappearance d - disappearance, but star is less than 1 mag brighter than the predicted visibility limit. R - reappearance r - reappearance, but star is less than 1 mag brighter than the predicted visibility limit. Gr - grazing occultation at site. At mid-occultation, or closest approach, the star is less than 4" from the limb of the moon (either above or below). gr - grazing occultation at site, but star is less than 1 mag brighter than the predicted visibility limit. M - miss. At closest approach, the star is more than 4" above the limb of the moon m - miss, but star is less than 1 mag brighter than the predicted visibility limit.
Star	The star identifier. Three formats are used: nnnn - A ZC star. When reporting occultations, the catalogue is identified with 'R'. nnnnn, or nnnnnn - An SAO star. When reporting occultations, the catalogue is identified with 'R'. X nnnnnn - an XZ star. When reporting occultations, the catalogue is identified with 'X'.
D	The double star code
Sp	Star's spectral type. Only basic spectral type information is provided
Mag v	The star's visual magnitude
Mag r	The star's red magnitude. For observers using CCD video cameras, the red magnitude provides a better indication of visibility.
D	The variable star code
% ill	the percent illumination of the moon. If followed by a +, values are for a waxing moon; - for a waning moon; and E for illumination during a lunar eclipse.
Elon	the elongation of the moon from the sun, in degrees. [Strictly, the quantity is calculated as the elongation of the star from the sun]
Sun Alt	the altitude of the sun. The field is blank if the sun is lower than -12 deg. (Nautical twilight)
Moon Alt	the altitude of the moon
Moon Az	the azimuth of the moon
CA	Cusp Angle - the angle of the event around the limb of the moon, measured from the nearest cusp. -'ve values indicate a bright limb event. The cusps are usually N (north) or S (south), but near full moon can be E (East) or W (west). If a lunar eclipse is in progress, CA gives is the % distance from the centre of the umbra, and is followed by a 'U'. Values up to 103% are possible. Where an event occurs more than 103% of the umbral radius, the usual Cusp Angle value is displayed.
PA	Position Angle - the angle of the event around the limb of the moon, measured from true north

Venus going behind the Moon - Lunar occultation on 30 june

2011-06-29T10:58:00.006+05:30

On 30th june afternoon, moon will come in front of venus as seen from earth, an event we term as occultation. Just like moon covering the sun which we call eclipse which should be called an occultation!! This event needs special mention here as its happening in "broad day light" in india!!! there have been night time lunar occultations of venus but its really a challange to search for a crescent moon with Venus in day light! Because of Monsoon we may miss the event but it wOuld be worthwhile for amateurs to try and get the occultation in daylight. but make sure that you are following the observation procedures. Moon would be TOO close to the sun - hardly 12 degrees. last time the event occurred on May 16th, 2010, also a daytime event.

Item	Meaning
Day	The day of the event. Occult searches for events on the basis of geocentric conjunctions that occur within a 24hr - with that period starting at the UT indicated in the date selection box. Users should ensure that the period starts near the middle of their day.
Time	The predicted UTC, in hours, mins and secs.
P	The Phase of the event. Values are: D - disappearance d - disappearance, but star is less than 1 mag brighter than the predicted visibility limit. R - reappearance r - reappearance, but star is less than 1 mag brighter than the predicted visibility limit. Gr - grazing occultation at site. At mid-occultation, or closest approach, the star is less than 4" from the limb of the moon (either above or below). gr - grazing occultation at site, but star is less than 1 mag brighter than the predicted visibility limit. M - miss. At closest approach, the star is more than 4" above the limb of the moon m - miss, but star is less than 1 mag brighter than the predicted visibility limit.
Star	The star identifier. Three formats are used: nnnn - A ZC star. When reporting occultations, the catalogue is identified with 'R'. nnnnn, or nnnnnn - An SAO star. When reporting occultations, the catalogue is identified with 'R'. X nnnnnn - an XZ star. When reporting occultations, the catalogue is identified with 'X'.
D	The double star code
Sp	Star's spectral type. Only basic spectral type information is provided
Mag v	The star's visual magnitude
Mag r	The star's red magnitude. For observers using CCD video cameras, the red magnitude provides a better indication of visibility.
D	The variable star code
% ill	the percent illumination of the moon. If followed by a +, values are for a waxing moon; - for a waning moon; and E for illumination during a lunar eclipse.
Elon	the elongation of the moon from the sun, in degrees. [Strictly, the quantity is calculated as the elongation of the star from the sun]
Sun Alt	the altitude of the sun. The field is blank if the sun is lower than -12 deg. (Nautical twilight)
Moon Alt	the altitude of the moon
Moon Az	the azimuth of the moon
CA	Cusp Angle - the angle of the event around the limb of the moon, measured from the nearest cusp. -'ve values indicate a bright limb event. The cusps are usually N (north) or S (south), but near full moon can be E (East) or W (west). If a lunar eclipse is in progress, CA gives is the % distance from the centre of the umbra, and is followed by a 'U'. Values up to 103% are possible. Where an event occurs more than 103% of the umbral radius, the usual Cusp Angle value is displayed.
PA	Position Angle - the angle of the event around the limb of the moon, measured from true north

It is shining in the West!

No! This is not an election advertisement! It is an advertisement for the god of good fortune Sukra or the goddess of love Venus (If you believe in Gods!!!!). Either way you should be interested. Venus has been shining and shining for the past few months imploring you to look at her/him! You can not step out after sunset and NOT see it in the western sky. There is something more to Venus than just being bright these days. What’s that? Let’s find out.

Planet Venus has dared to let the sun go ahead and has venturing further and further away in the sky from the sun and finally it will stop for a well earned rest on August 20^th, well that’s another story to tell about the phenomenon called eastern elongation. But Venus seems to be enjoying this independence from the sun right now. It glows brightest now!

After few days its all set to date Moon. Looks like an interesting event, Venus dating a crescent moon. Not even dating, trying to hide behind moon, away from the glaring lights and cameras of news channels. But even these probing eyes of reporters and sting operations would not stop it meeting Moon on 16^th afternoon. This event in astronomy is called occultation. Remember, sun hiding behind the moon? You are right, during solar eclipse it does that, technically solar eclipse is an occultation. An occultation is an event that occurs when one object is hidden by another object that passes between it and the observer. Last time it happened with venus for India was on June 17 2007. This event is not rare one but it sure is an event to watch as bright Venus slips behind the moon.

Now why this event occurs? As we all know that Moon goes around the Earth and during it journey it comes in front of rest of the celestial bodies. Sun, planets, stars to name a few. As a result we have all sorts of occultations. As moon moves quite fast in the skies, it comes back to the same phase in about 29.5 days, it stands a good chance to occult the planets and stars. A planet being hidden by moon is not a common event as there are only few bright naked eye planets, even then it usually hides Venus behind at least once in a year.

Timings for Delhi

16 May, 2010

Disappearance 15 50 38 IST

Reappearance 17 18 31 IST

For timings in rest of the major cities in delhi, please visit SPACE occultation blog at http://occultationindia.blogspot.com

It is a daytime event. Last time its happened during night/eve but next two events are daytime and one has to wait till 2036 to see this event in night.

Next three events

June 30, 2011 Daytime event

Feb 26, 2014 Daytime event

Sep 16, 2036 NightTime event

How to see the event?

As the event is happening in the daytime, one can not see the venus going behind or coming from behind the moon but it will be site worth to watch once the sun has set and Moon-Venus pair shining in the western skies.

Event for Amateur Astronomers

Amateur Astronomers can try out photographing the event as well seeing the venus in broad daylight with help of data available for the venus and Moon, but its not going to be easy.

The map shows the area over which the event can be seen.

Continuous thick white line indicates night-time region. Red line indicates twilight region. Dotted white line shows daylight region

On Sunday, May 16, 2010, the Moon will come directly between Venus and the Earth. The event would be visible from India during the day time.

Last time it happened for observers in india on June 18, 2007 and next will be in June 30, 2011

Venus is the brightest planet visible from the Earth and can be seen with the naked eyes in the board day light, if one knows were to look for it. This event provides a wonderful opportunity to look for Venus even when the sun is well above the horizon.

For India the event begins after about 3:30 p.m. Indian time and ends after 5 p.m. The start and end times of the event are given in the table below. At the start of the event the Moon and Venus will be well above the horizon. The Moon itself will be about 30 degrees east of the Sun. It will not be very difficult to spot the Moon if the sky is clear and blue. All one needs to do is to face west and look about 30 degrees above the sun.. Needless to say that one should not look at the sun directly.

Venus will be a bit east of the Moon. With the reference of the Moon, it would be easier to spot the planet with the naked eyes. A pair of binoculars, however, would be most useful. But if you are using a binoculars or telescope be very sure not to point the instrument in the direction of the sun. It is quite likely that one may not be able to see the dark limb of the Moon.

On 2010 May 11 18:11 UT (23:43 IST), the 37 km diameter asteroid (7476) Ogilsbie will occult a 5.0 mag star in the constellation Virgo for observers along a path across Japan,China, India, Africa. In the case of an occultation, the combined light of the asteroid and the star will drop by 9.3 mag to 14.3 mag (the magnitude of the asteroid) for at most 2.7 seconds. This sure is a very good event to observe as comparitevly bright star (5.o mag) is going to be occulted and the central path is passing quite near to Banglore, tirupati and few
other cities in south. SPACE is going to observe and record the event. More updates will soon be put up.

Pleiades occultation by Moon oN Dec 1st, 2009

Eclipse of stars in night

Imagine moon covering the sun to bring darkness in broad daylight, what would that event be? Eclipse, you would say but is it really eclipse? Well give it a thought. We know eclipse as “An astronomical object coming under shadow of another astronomical body and seen from other astronomical body” but the solar eclipse is not coming under this category because we are on the object where shadow is falling. So then what is this event? In astronomy we call it an “occultation” which means that a celestial body is directly coming in front and blocking the light from another body. Solar eclipse is a perfect example of occultation.

Now the greatest eclipse of the century is history and why we are discussing this again? Moon, our nearest neighbor, keeps on coming in front of so many stars in night that each night one can see numerous occultations. So one does not have to wait for a solar eclipse to happen to see an occultation. Now the whole talk about occultation goes to an interesting juncture where moon comes in front of a group of stars and in span of few hours you see 10-15 stars being occulted. As the occultation can and only happen with stars and planets and lying on the path of ecliptic, some interesting events occur. Pleiades star cluster happens to be in Taurus and it provides us humans a rare treat in visual astronomy when moon comes in front of it.

December 1st 2009 night is one of those nights when moon is coming in front of the Pleiades as seen from earth and we get a chance to see this event though the moon is almost full and most of the Pleiades stars get washed out in the brilliance of it.

Occultation of Pleiades photographed by SPACE team on March 30, 2009

Occultations have been used to know more about the celestial mechanics as well as these have helped us finding new things in the skies. The discovery of the Uranian Rings was made by astronomers James L. Elliot, Edward W. Dunham, and Douglas J. Mink on March 10, 1977, using the Kuiper Airborne Observatory, and it was an unexpected event. They planned to use the occultation of the star SAO 158687 by Uranus to study the planet's atmosphere. However, when their observations were analyzed, they found that the star disappeared briefly from view five times both before and after it was eclipsed by the planet. They deduced that a system of narrow rings was present. Observations of occultation by Neptune were observed by UP state Observtaory, nainitaal and they confirmed presence of rings around Neptune. Stellar occultations by Moon gives us more and more accurate data about the Lunar orbit.

On December 1st 2009, around 7:00 pm IST get hold of any optical astronomical instrument you have. Binocular, spotting scope, small refracting scope or a telescope. These all will show you the moon sitting pretty in front of Pleiades.

What is an Asteroid Occultation ?

What is an Asteroid Occultation ?

Occultation is a generic astronomical term for a situation where one body "covers" or "passes in front of" another body. Eclipses and transits are common examples of occultations. In a solar eclipse, the moon occults (covers) the sun for observers on the earth. In a lunar eclipse, the earth occults the sun for observers on the moon. We use the term asteroid occultation for the situation where an asteroid occults a star for observers on the earth. During an asteroid occultation "event" the asteroid momentarily hides the star. We use the term "asteroid's shadow" to refer to the "shadow" thrown by the asteroid with respect to the light from the occulted star. And the term "shadow path" refers to the path of the asteroid's shadow as it passes across the earth. Depending on the size of the asteroid, its distance from the earth, and its speed in its orbit, the asteroid may cover the star for a fraction of a second or close to a minute. If the star is relatively bright compared to the asteroid, an observer will see a noticeable drop in magnitude as when the asteroid covers the star. As asteroids move through the sky they often pass in front of stars from the perspective of an observer on the earth. However, the vast majority of these occultations involve small asteroids and relatively dim stars, and these events would be very hard to detect with amateur equipment.
