CT Hya outburst

　vsnet-alert 等で連絡の通り、CT Hya がアウトバーストです。初期の変動を捉える
　のに絶好の機会ではないかと思われますが、CW Mon, SW UMa もまだ重要なターゲ
　ットなので、観測対象を分散する方がよさそうです。CW Mon は MEI/NEKO さん、
　岡山理科大チームの方々がよい観測を残されていますので、鳥居さんところの
　２台めの機器で CT Hya は届くでしょうか？（KV And の後半が犠牲になるのは
　構わないと思います）。

  As reported by Rod Stubbings, the large-amplitude SU UMa-type dwarf nova
CT Hya is undergoing a bright outburst.  The outburst may be a superoutburst.
The last reported superoutburst occurred in 2000 December.  Although several
past superoutbursts have been observed by the VSNET Collaboration, early
coverage of a likely superoutburst is still very wanted.

  The star was claimed to be something intermediate between usual SU UMa
stars and WZ Sge-type stars (or TOADs), see Nogami et al. 1996
(PASJ 48, 607).  Early coverage is thus extremeely important to see
whether there is any similarity of the superhump growth with WZ Sge-type
stars.
