I made the following observations last night around the predicted times of
eclipses at 14:38 and 16:09 UT on Feb 23rd of OY Car as detailed below:

Time (UT) Mag

14:35          11.6
14:37          11.6
14:38          11.7
14:39          11.6

14:45          11.5
14:47          11.4

15:50          11.5
15:56          11.5
15:57          11.5
15:59          11.5
16:01          11.6
16:02          11.6
16:03          11.6
16:04          11.6
16:05          11.6
16:06          11.7
16:07          11.7
16:08          11.7
16:09          11.7
16:10          11.7
16:11          11.6
16:12          11.6
16:13          11.6
16:14          11.5
16:16          11.6
16:18          11.6
16:19          11.5

There was a distinct drop in brightness at the times of predicted eclipses
although the amplitude only amounted to approximately 0.2 mag, however this was
discernible visually.  The comparison star magnitudes were from the Tycho-2 data
as displayed on the VSNET.

The amplitude of the eclipses appeared a lot less than the eclipse observed the
previous night, however observations made tonight were more accurate.

I hope to observe further eclipses on Feb 24th.

Regards
Andrew Pearce (PEX)
