RX J2315.5-3049 outburst : WZ Sge-like?

　驚くべき情報が入ってきました。Stubbingsが13.4等でアウトバーストを発見した
　このROSAT sourceですが（その後の光度情報がありません）、WZ Sge型ではないか
　（しかも浅い食がある？）という静穏観測があるそうです。ちょっと南の天体で
　すが、これはもう見るしかありませんね。

Dear all,

this source has been independently found in the Calan-Tololo 
objective prism plate survey. From follow-up photometry and 
spectroscopy we have found an orbital period of 0.058 day.
The quiescent light curve of the source is very similar to
that of WZ Sge, including a narrow ~0.3 mag eclipse (which
in the case of WZ Sge is probably an eclipse of the hot spot). 
Given the short orbital period this source is most likely a 
SU UMa type dwarf novae and superhumps should be detected if 
this is a superoutburst.
