Station Map for the Occultation by (1251) Hedera at Friday 2008 December 19 (~ 21:58 UT)
V-Magnitude of target star TYC 1315-01390-1: 10.6 mag
Johnson B-V Colour Index: + 0.0
The UCAC2 gives a “pseudo-R magnitude” of 10.5 mag
The max duration is expected to be 2.2 sec with a max drop of 3.5 mag.
The event will take place at an altitude of 51 deg and at azimuth 126 deg. The sun will be at an altitude of -61 deg. (At predicted centre line for longitude E 05 deg)
There is a 1 sigma uncertainty interval of ± 1.34 path widths.
The probabilities to see a positive event:
Centre line: ~ 29 %
Path limits: ~ 27 %
1 sigma lines: ~12 %
2 sigma lines: ~ 1 %
(Calculation according to Raymond Dusser, E.A.O.N. Circular #10)
PLEASE REMEMBER: Predictions are sometimes wrong. Please observe even with a small probability.
