Station Maps for the Occultation by (372) Palma at Wednesday, 2011 August 10 (~ 22:09 UT)
NORTH and SOUTH
Magnitude of target star 2UCAC 42524779: 13.3 mag
UCAC instrumental „pseudo-R“ fit-model magnitude: 13.3 mag (data from UCAC3)
In the case of an occultation, the combined light of the asteroid and the star will drop by 0.3 mag to 12.2 mag (the magnitude of the asteroid).
The max duration is expected to be 12.4 sec with a max drop of 0.34 mag.
The event will take place at an altitude of 29 deg and at azimuth 75 deg. The sun will be at an altitude of -25 deg. (At predicted centre line for longitude E 11 deg 3 min)
There is a 1 sigma uncertainty interval of ± 0.59 path widths.
The probabilities to see a positive event:
Centre line: ~ 60 %
Path limits: ~ 45 %
1 sigma lines: ~ 16 %
2 sigma lines: ~ 2 %
(Calculation according to Raymond Dusser, E.A.O.N. Circular #10)
PLEASE REMEMBER: Predictions are sometimes wrong. Please observe even with a small probability.
