SW UMa outburst なんとなんと、SW UMaがアウトバースト。前回が1997年10月で、今回もスーパー アウトバーストの可能性がありそうです。時期もよく、観測をお薦めします。 (CCD測光の場合は光度も明るくなる可能性があり、積分時間は10-30秒程度 でばんばん連続撮像をおすすめします)。 From: Gary Poyner <gp@star.sr.bham.ac.uk> Subject: [vsnet-alert 2609] SW UMa Chris Jones (Basildon, Essex UK) reports that SW UMa is in outburst.
