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.
