[vsnet-campaign 680] RZ Leo rebrightening observation

RZ Leo rebrightening observation

Dear Colleagues,

   Preliminary analysis of the RZ Leo data on Jan. 12 shows that the object
has not yet entered the rapid decline from the rebrightening.  The object
was about 0.8 mag fainter than on Jan. 11, but remained sufficiently
bright.  This behavior seems to be different from that of UV Per, and
seems to more resemble the early stage of the rebrightening of AL Com
in 1995 (see Nogami et al. in the preceding post).  AL Com showed a
relatively rapid decline, followed by a second, bright (plateau) state,
which Nogami et al. interpreted as the second superoutburst.  Intensive
observations are very strongly needed at this extremely important stage.
More detailed analysis will be presented by Ishioka-san et al.

   Even in the strong interference from the Moon, successive short exposures
enough to avoid saturation (of the comparison) and stacking frames in the
later analysis is known to efficiently record the object under such difficult
conditions.  Please, with all your efforts and technique, record the
behavior of this rarely met outburst!  The VSNET Collaboration team
is willing to receive raw images and make detailed analysis, if the above
analysis is difficult at the observer's side.

Regards,
VSNET Collaboration team
