Station Map for the Occultation by (1299) Mertona at Friday, 2009 February 13 (~ 18:45 UT)
V-Magnitude of target star TYC 0742-01423-1: 9.2 mag
Johnson B-V Colour Index: + 0.1
The UCAC2 gives a „pseudo-R magnitude“ of 9.3 mag
The max duration is expected to be 3.7 sec with a max drop of 6.2 mag.
The event will take place at an altitude of 61 deg and at azimuth 164 deg. The sun will be at an altitude of -29 deg. (At predicted centre line for longitude E 20 deg)
There is a 1 sigma uncertainty interval of ± 2.95 path widths.
The probabilities to see a positive event:
Centre line: ~ 14 %
Path limits: ~ 13 %
1 sigma lines: ~ 7 %
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.
