(cba:news) OT_J130030.3+115101 superoutburst continues (Joe Patterson) [2008-07-04T15:09:49Z]

Dear CBAers,
This star is poorly situated in the sky, but it's the first-observed-by-humans outburst, which adds interest... and at 13-14 mag is a solid object on CBA radar screens. It's a good target while waiting for VY Aqr to rise.
No one observer can get satisfactorily long runs on this star, but we should be able to splice 'em together over a range of longitudes - so that at least the basic period-finding issues are clarified. 

The official and useful name, I suppose, is SDSS J130030.33+115101.2.
The attached reference (nesssi) gives a chart that should allow you to
find the star.

  The following Catalina transient has a blue quiescent counterpart
(with a relatively high proper motion).
This appears to be an outburst of a dwarf nova.

   ASAS-3 also detected this outburst.  The decline rate is not incompatible
with that of a superoutburst.  Time-resolved photometry is encouraged.
