Dear colleagues,

Outburst of an UG-type cataclysmic variable AF Cam was detected on
Feb. 12 in the course of the MISAO Project.

  AF Cam  03h32m15s.5 +58o47'22"  Mag(max):13.4  Mag(min):17.6
          MagSystem:p  Type:UG  Period:(74.9)

Here is our data in VSNET format:

CAMAF 20070212.54081 138C Mis
CAMAF 20070212.54360 137C Mis
CAMAF 20070219.49722 165C Mis
CAMAF 20070219.50291 165C Mis

2007 Feb. 12-19
  Nobuo Ohkura and Youichirou Nakashima
  0.25-m f/4.2 Wright-Schmidt reflector + SBIG ST-1001E

2007 Feb. 23
  Youichirou Nakashima
  0.25-m f/4.2 Wright-Schmidt reflector + SBIG ST-1001E

There are several survey images between 1999 and 2002 in the MISAO
Project database. However, AF Cam had never been brighter than 16.5
mag before.

Following observations were reported to VSOLJ:

  2007 Jan. 11 15h10m(UT)  <14.1  Mdy
  2007 Jan. 17 14h54m(UT)  <13.7  Mdy
  2007 Feb. 12 14h02m(UT)  <14.1  Mdy

Yutaka Maeda reported it as "not seen" on Feb. 12, just on the same
day when Nobuo Ohkura and Youichirou Nakashima detected its outburst.

P.S.
It is too late to report, so I do not post it to vsnet-alert.

Best regards,
