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,
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,
Josch

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.
