T CrB oscillations tonight.

Hi Maxim,

Yes, I see considerable variability (and variability of variability night on night!). You can see the vertical spread over each night on this plot. I usually take 40 to 60 images per filter per night. It’s hard to display as the points get very bunched and I would have to expand just one or two nights to see the details.

Also, overall since April, T CrB has been quite steady especially in the past two or three weeks.

Cheers
Ian.
