(cba:news) BW SCL bright outburst (v=9.6)! (Joe Patterson) [2011-10-21T11:47:15Z]



Holy mackerel! Is this true? Linnolt's record is pretty good. Can someone confirm? And can everyone skip work, and work on this star tree-to-tree?

Waiting for BW Scl to erupt - it's been a long vigil. If true, it's certainly the most important dwarf-nova eruption since WZ Sge in 1978. Despite the brevity of this message, it took me a long time to write it. I made about 50 errors - from trembling fingers!

Just yesterday, our paper (Helena Uthas et al., MNRAS) on BW Scl at quiescence was finally accepted. She'll forward it in a few days. I don't remember including any "keep up a close watch" exhortation - but as many of you know, it's been on the prime WZ Sge watch-list for a long time... tied for #1 with GD 552 and MT Com.

 According to M. Linnolt (via Aavso-discussion list), BW Scl is undergoing
a bright outburst. The orbital period of this object is 78.2 min (Augusteijn,
T. & Wisotzki, L. A&A 324, 57-60, 1997). The object is likely a WZ Sge-type
dwarf nova. Time-resolved observations are encouraged.
