[vsnet-campaign 1025] WZ Sge outburst: Kyoto observation
Kyoto team started tonight observation at 11:10 (UT). We plan to
take a run on WZ Sge whole night. The object is clearly brighter than
bright comparison star (GSC 1612.1830 V=8.5). We estimate the object
is about 8.1 mag now (12:10 UT).
Last night observation during 23.6 - 23.8 UT shows that WZ Sge was
rapidly brightening. Its magnitude was Rc~9.7 mag at the start time
and Rc~8.7 mag at the end time. The rising rate was about 5 mag / day.
In addition, short-term modulations with time-scales of 0.01 - 0.03 d
are superimposed on the rising trend.
Following observations are urgently encouraged!!
