[vsolj-alert 380] HT Cas!!!!



HT Cas!!!!

 どうもスーパーアウトバーストの可能性濃厚です。後半夜の天体ですが、観測可
 能でしょう。今後のsuperhumpの発達と食の関係の観測が極めて重要です。

HT CASSIOPEIAE  (UGSU+E)
July 25.931 UT, [13.3 ; 26.087, [13.6 ; 26.925,  12.5:; 27.090,  12.7 ; 
     27.093 UT,  12.3 
Part of eclipse egress observed.
Some haze + clouds + full moon
The most recent superoutburst of HT Cas occurred in 1985 January,
when the star peaked at mv= 10.8 (cf. IAUC 4027). This magnitude 
estimate, however, may be too bright by about one magnitude if it
is based on the old AAVSO sequence.
High-speed photometry during the current outburst is (of course)
urgently required.
