Tárgy: Kisbolygo fed csillagot
Sziasztok!
Az OKKULT c. listánkon jelent meg, de próbaképp osszuk meg az egész Nagyérdeművel:

Vasárnap napnyugta után egy 5,9 magnitúdós csillagot fed el a 830 ZENOBIA
kisbolygó. A fedés akár 5 cm-es binokulárral is megfigyelheto, bár még
szürkület lesz. Az alábbi linkeken található információ.

Dear observers,
you'll find attached the station map for the occultation by (840)
Zenobia at Sunday, 2007 January 14 (~ 16:23 UT).
V-Magnitude of target star HIP 29196: 5.9 mag
Spectral Class: K4III
Johnson B-V Colour Index: + 1.6
The max duration is expected to be 2.2 sec with a max drop of 8.5 mag.
The event will take place at an altitude of 24 deg and at azimuth 83
deg. The sun will be at an altitude - 08 deg. (At predicted centre line
for longitude E 15 deg).
