(cba:news) Fwd: (cba:chat) Fwd: [vsnet-alert 16982] SDSS J090221.35+381941.9 outburst! (Joe Patterson) [2014-03-07T15:03:11Z]

I'll say! Glorious new object, and let's fire with all cylinders. The AM CVn outbursts, even the supers, don't usually last long. Just a spectacular new CBA target!

And it's time now to pick up the monitoring of V1159 Ori in the evening sky. In a week the Suzaku observation will start. We definitely want snapshots to cover its wanderings in the 4 d mini-outburst cycle... but also time series to monitor for superhumps (the latter applying to the Suzaku times mainly, so for now the monitoring is the main thing).

... And yet another interesting short-period AM CVn-type target found in outburst by MASTER.
