Announcement: New Applications
We are excited to announce the launch of our new applications! We're opening up early access to our new applications for searching, downloading, and submitting photometric observations. You can now access these applications through these links:
We ask for your feedback in order to help us improve these applications. Please send feedback for the applications above to feedback@aavso.org. Note: please avoid duplicating submissions across the two submit applications.
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.
