Great target for the present full moon conditions. We've never properly caught one of these. Outbursts are typically short, so hop to it, Thanks so much, Enrique, for staying on top of the dwarf novae. But also, it would be great if northern observers got long runs on BZ Cam, as he requested. A bright star seemingly about to cough up some long-held secrets. joe -------- Forwarded Message -------- EX Hya outburst ASAS-SN detection. Eclipsing intermediate polar.

The negative-superhump signal is roaring away, as it did last year, and the 100-day coverage is plenty good. BTW here is a fascinating pic and brief description of this amazing star: http://apod.nasa.gov/apod/ap001128.html Here's a promising new intermediate-polar candidate, with light curves from Arizona (attached). At 17.5, it's not the easiest target - but not super-difficult, and likely to yield both orbital and rotational signals of good accuracy. The coords are 06 14 12.28 +17 04 32.6, and the comp star fro these nights is at 6 14 14.72 +17 04 32.0 - although feel free to use a different comparsion star (this one was appropriate for a 1.3 m telescope, but you might want a brighter one!). T Aurigae continues to be a very good target, too. joe -------------- next part -------------- A non-text attachment was scrubbed...
