[vsnet-j 861] IY UMa outburst



IY UMa outburst

 IY UMa = TmzV85 が増光しました。光度的にはノーマルっぽいですが、観測が
 望まれます。なお、この天体は近い時期に「すばる」での観測が予定されており
 (実現すれば実はものすごくすごいことだったりするのですが...)、それに先
 立って食の位相を正確に決めておくことが非常に重要になっています。
 このような観測は明るい時期に行うのが非常に効率的ですので、観測可能な方は
 ぜひ連続観測にトライしていただければと思います。(概算の予報は植村君の方
 からあるかと思います)

#長谷田さんの再発見の V893 Sco といい、大望遠鏡をも動かす新天体発見、という
#のはすごいことです。

   According to Timo Kinnunen, the northern eclipsing SU UMa-type dwarf nova
IY UMa (=TmzV85) is in outburst!

   From vsnet-obs 32645:

> UMAIY        010304.943  14.3   KNN  outburst
> UMAIY        010304.958  14.3   KNN
> UMAIY        010304.992  14.8:  KNN

   Although this outburst looks like a normal outburst, eclipse observations
during the present outburst in highly encouraged.  The present good visibility
would provide an excellent opprotunity to precisely determine the eclipse
ephemeris necessary for future detailed observations with large telescopes
and/or from space, as well as to investigate the evolution of the disk
during normal outburst.
