BZ Cam : Atypically rapid and strong activity in 2001
M. Reszelski and H. Itoh independently detected a sudden
fading to 13.1mag of the VY Scl-type variable BZ Cam on February 11.
The last fading (the second historical fading) of BZ Cam occurred
in 1998
(vsnet-campaign 762).
It has however rapidly recovered from the fading to 12.4mag on February
15
(vsnet-campaign 765).
These fast activity is atypical for this class, and the active state
continued throughout 2001: After the rapid recovering, the object
again faded
(vsnet-campaign 787).
Except for a possible brightening reported on February 25
(vsnet-campaign 796),
the slightly faint state continued until April
(vsnet-campaign-nl 8),
when the object started gradual recovering
(vsnet-campaign-nl 13).
The object then entered a bright state around 12.2mag
(vsnet-campaign-nl 15).
(After a temporary fading on September), H. Itoh reported that BZ Cam
again faded to 13.1mag. BZ Cam recovered from this short fading in
the end of November
(vsnet-campaign-nl 56).
T. Kato commented that if this indeed is an
excursion to a low state, this star seems to be quite active in recent
years
(vsnet-campaign-nl 55).
