WZ Sge: 12-th rebrightening, a different one!
Dear Colleagues,
Very preliminary analysis of the Kyoto data last night has shown that
WZ Sge took a (very) slow rise between Sep. 11.5 and 12.5. The object has
further risen since the preceding observation by D. Starkey.
The rise time of ~1 d is extremely long compared to those of the previous
rebrightenings. This suggest that the present rebrightening has a different
nature from the past rebrightenings. It would be noteworthy that the
6-th (last) rebrightening of EG Cnc had a substantially slower rise,
accompanied with a slow rise lasting more than a day before reaching maximum
(Kato et al. 1997). Observers are most strongly and urgently requested to
follow the behavior of WZ Sge!
The time-series light curve looks rather flat, pending further detailed
analysis. More later.
Regards,
Taichi Kato
