Very rare
outburst of NSV00907 in March 2004
On March 2nd, 2004,
Patrick Schmeer announced in a message to cba-news
his detection of a rare outburst of NSV00907 :
"The CV candidate NSV 907 is visible in
outburst on an unfiltered CCD
image
taken with the University of Iowa's Rigel telescope:
NSV00907 20040302.106 135C Scp. The
only previously recorded outburst of NSV 907 = Ross
182 occurred on 1926 Nov. 26
(mpg= 11). ... NSV 907 is probably identical with
the ROSAT source 1RXS
J024459.2+273126".
I started an unfiltered CCD
photometry session on this object on the evening of
Mar 02/03, 2004, and collected CCD images for 2.2 h
(0.35-m f/6.3 telescope). The variable was at about
mag 13.9 (unfiltered).
The resulting light curve (see below) shows a
decline by 0.2 mag over the observation interval,
but no obvious periodic modulation. Due to the
unfavourable location of the variable over the
Belgian horizon, I could not follow it for a longer
period.
