V-Magnitude of target star TYC 5369-01307-1: 10.7 mag
Johnson B-V Colour Index: + 0.4
The UCAC2 gives a „pseudo-R magnitude“ of  10.8 mag

The max duration is expected to be 8.9 sec with a max drop of 2.2 mag.
The event will take place at an altitude of  34 deg and at azimuth 156 deg. The sun will be at an altitude of – 51 deg. (At predicted centre line for longitude 0 deg)

There is a 1 sigma uncertainty interval of  ± 0.31  path widths.
The probabilities to see a positive event:

Centre line: ~  90 %
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.
Let other observers know about you observing plans: Announce you station with OccultWatcher !

Station Map for the Occultation by (402) Chloe at Thursday, 2009 January 08 (~ 17:08 UT)

V-Magnitude of target star TYC 0724-01025-1: 11.5 mag
Johnson B-V Colour Index: + 0.4
The UCAC2 gives a „pseudo-R magnitude“ of 11.5 mag

The max duration is expected to be 5.3 sec with a max drop of 1.2 mag.
The event will take place at an altitude of 20 deg and at azimuth 95 deg. The sun will be at an altitude of -14 deg. (At predicted centre line for longitude E 10 deg)

There is a 1 sigma uncertainty interval of  ±  0.51 path widths.
The probabilities to see a positive event:

Centre line: ~  67 %
Path limits: ~  47 %
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.
Let other observers know about you observing plans: Announce you station with OccultWatcher !
