Station Map for the Occultation by (361) Bononia at Saturday, 2008 December 06 (~ 02:16 UT)
SUSPECTED DOUBLE ASTEROID!
Trans-Atlantic Event! Path is crossing Canada too.
V-Magnitude of target star TYC 1789-00112-1: 10.4 mag
Spectral Type: A2
Johnson B-V Colour Index: + 0.3
The UCAC2 gives a „pseudo-R magnitude“ of 10.5 mag
The max duration is expected to be 14.6 sec with a max drop of 2.8 mag.
The event will take place at an altitude of 27 deg and at azimuth 280 deg. The sun will be at an altitude of -39 deg. (At predicted centre line for longitude E 15 deg)
There is a 1 sigma uncertainty interval of ± 0.33 path widths.
The probabilities to see a positive event:
Centre line: ~ 87 %
Path limits: ~ 50 %
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.
