Any measures on the bright CV BV Cen now and for a week or two will be usefull. It's a CV system that's been changing...

Best to all....

Hi,

what kind of measurements do you need/mean? Snapshots (one image anight) of time series. I could add this star to my observing program.

Regards,

Hi Josch. Snapshot every

Hi Josch. Snapshot every night is fine. My climate is bad now. 13th mag (flickering) in quiescence and a 2 or 3 mag amplitude in outburst. I've just had two nights at 11.2 or 3 vis mag, and don't even know if it's rising or falling. It has an outburst shape like GK Per - slow rise to peak and slow fall. for BV Cen over a fortnight or so if I remember correctly. The accretion rate is being modulated by something, But modulated erratically. Could be a magnetic cycle in the secondary, and / or something else.

Hi Alan,

My transformed CCD observations of BV Cen last night were:

2457868.00284 B filter 11.581 (0.050)

2457868.00427 V filter 11.410 (0.022)

2457868.00572 R filter 11.200 (0.022)

I'll make further observations as weather permits. Cheers,

Mark

HI,

I have added it in snapshot mode in V only. So from tomorrow onwards I will send data to the AAVSO.
