Station Map for the Occultation by (29943) 1999 JZ78 at Wednesday, 2008 December 31 (~ 00:20 UT)

V-Magnitude of target star TYC 1906-00192-1: 9.8 mag
Johnson B-V Colour Index: + 0.4
The UCAC2 gives a „pseudo-R magnitude“ of  9.7 mag

The max duration is expected to be 2.0 sec with a max drop of 4.1 mag.
The event will take place at an altitude of 74 deg and at azimuth 204 deg. The sun will be at an altitude of -69 deg. (At predicted centre line for longitude E 05 deg)

There is a 1 sigma uncertainty interval of  ±  4.48 path widths.
The probabilities to see a positive event:

Centre line: ~ 9 %
Path limits: ~  9 %
1 sigma lines:  ~ 5 %
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.
