[vsnet-alert 3975] Re: CW Mon - first results

["William S G Walker" <astroman@voyager.co.nz>]

Hi All,

OK, I've got the note regarding RXJ whatever. If it clears tonight I may
switch to that. I ran on CW Mon for 5.5 hours. There are eclipses ~0.4 mags
depth at 2000 Jan 08.40231 and Jan 08.57692. Close to the period of 4.229
hours. I'll post the actual data later in the day as I want to catch some
yachting and cricket!

There are also some oscillations of the type mentioned by Tonny and Eric -
actually the star looks like an IP but not as regular! Maybe it's all just
the normal flickering.

Regards,
Stan
