(Pearce) OY Car eclipse From: andrew.pearce@clough.com.au Date: Wed, 23 Feb 2000 09:20:23 +0800 Subject: OY Car Further to my observation of the eclipse for OY Car last night, I have redone the magnitude estimates utilising the Tycho-2 magnitudes of the OY Car Chart GIF file on VSNET. These magnitudes extend down to 12.0. There is a distinct difference in the comparison star magnitudes between the Tycho-2 data and the current comparison star mags I have on my chart. Generally the Tycho-2 mags are brighter. There is a star NW of OY Car which has a magnitude of 12.5 which does not have a corresponding Tycho-2 magnitude which has also been used for the estimates. Feb 22nd Time (UT) Mag 13:59 11.2 14:24 12.4 14:26 12.1 14:27 11.8 14:28 11.6 14:30 11.3 14:31 11.3 I hope to view further eclipses tonight. Regards Andrew Pearce
