A couple of months ago I was asked to give an update at the July 2 2025 ASSA general meeting about T CrB, the binary star system that is anticipated to reach magnitude 2 or 3 when it goes into outburst as a recurrent nova (one of only 10 known), which it has done a few times before at roughly 80 year intervals.
In the meantime, we had two bright southern hemisphere novae (around magnitude 5) in June, so my T CrB talk turned into an update about 3 novae: T CrB, V462 Lup, and V572 Vel. The second and third were the subject of my last two posts.
My update was followed by a great talk about variable star photometry with the Seestar S50 by a former colleague, Andrew Murphy. The slides for his talk (and a course project) are here, as of 20 July 2025.
Here’s the PDF for the talk I gave, with thanks to Kym Thalassoudis for allowing me to include his images of V462 Lup and V572 Vel:
Here are the Powerpoint slides as well:
