(cba:news) scratch another star from Aquila (Joe Patterson) [2013-07-18T22:00:49Z]


A quick look at the V1315 Aql data suggests that its superhump is dormant this year (well, this week). So let's take it off the menu for the rest of the year.

However, the variable X-ray source is definitely variable at visual wavelengths - and is it ever! It varies by about 2 magnitudes, on many timescales, and the spectrum looks like some kind of very high-excitation mass transfer binary, probably a CV or LMXB. A great, great target for intensive followup with long time series!

That's Swift J2124.6+0500, in Equuleus, the Little Horse.
