(cba:news) V1315 Aquilae (Joe Patterson) [2015-07-30T23:24:26Z]


Hi CBAers,

The last 3 nights, by Jim Jones and Orville Brettman, show that V1315 is displaying strong superhumps again - the signals with period slightly shorter than Porb (which *defines* negative superhumps), PLUS the long-period (beat of Porb and Pnsh) wave which is allegedly the wobble period of the accretion disk.

Outstanding! And the reason to keep this campaign going (maybe with some AU-NZ coverage too, to get closer to global coverage?). So, contrary to my earlier message, the top northern target now is not GD 552, but V1315 Aql.

Jim is using the 137 star (000-BKG-531, V-13.735) as a comparison, so that would be a good choice. Orville is using AUID 000-BKG-529, so that might be good too.

P.S. The 2004 and 2012 campaigns on V1315 Aql very likely also showed these signals. The results were not as precise or as certain as we could accomplish this year, given the seasonal timing and the improvements in our network. Maybe V1315, unlike the other "permanent" superhumpers, really does have permanent superhumps.
