Map for india for 29th November event

Map for india for 30th November event

Two good asteroidal occultations coming up last week of Novembe


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
