The Saturn System Occults HIP 42705
Saturn and its rings will occult the 8th mag star HIP 42705 on the
25th of January 2006 in the hours around 20h UTC. The event is visible
from large part of the world, including Europe, nearly all Asia and
Africa as well.

HIP 42705 = HD 74050 = PPM 125631 = SAO 98054 = TYC 1395-1113-1
From the SIMBAD site the following photometric informations are
Photometric measurements from the JP11 catalogue:
Spectral type A7Vn reference: 1956PASP
|Diff to G2 star
In the table you see the intensities in the wavelengthbands for the
star from the JP11 catalogue. The difference to a G2 star is given in
the last column of the table. It means, that in the U Band the star is
about 0.5m brighter compared to a G2 star with the same magnitude in V.
In the R-Band the star is 0.25mag fainter as compared to a G2 star.
Using a strong blue filter therefore can improve the detectability with
respect to Saturns ring.
More infos to tomorrow (24th of January), if tests this night with
different cameras will be successful!
