CI CYGNI
Further to the outburst detected by Guy Hurst visually on Aug 22.90UT 
and reported on TA E-Circular 2476, U. Munari and A. Siviero, 
Astronomical Observatory of Padova et. al., report on CBET 1487 that the 
symbiotic star CI Cyg is currently on the rise toward a bright outburst. 
The previous outburst peaked in brightness in July 1975 when it reached 
V =8.6.  The mean values obtained with various telescopes of the ANS 
collaboration between Aug. 31.85 and Sept. 1.05 UT are V = 9.66, B-V = 
+0.84, V-R_c = +0.89, and V-I_c = +2.11. It is interesting to note that 
the outburst is occurring in coincidence with egress from eclipse of the 
outbursting white dwarf orbited by the late-type giant companion. The 
centre of the eclipse is predicted to have occurred between late June 
and mid August, according to the various ephemerides available.

SUPERNOVA 2008fc IN UGC 2883
Discovery by LOSS of a possible supernova (CBET 1481):
SN      2008 UT      R.A.  (2000.0)  Decl.    Mag.     Offset
2008fc  Aug. 25.51  03 52 12.91  -01 30 30.9  16.6    17.8"W, 1.3"S
M. Modjaz and R. Chornock, University of California, Berkeley et. al., 
report that inspection of CCD spectra obtained with LRIS on the Keck I 
10-m telescope on Aug. 27.55UT reveals it is a type-II supernova within 
a couple of weeks after explosion.

Guy Hurst reports that photometry of the supernova from an image 
obtained with the Bradford Robotic Telescope on 2008 Sept 3 (05h07mUT) 
gives an unfiltered magnitude of 16.5 (+/-0.1).

SUPERNOVA 2008fd IN ESO 466-G24
Discovery by the CHASE project of a possible supernova (CBET 1483):

R. Chornock et. al., University of California, Berkeley, report that 
inspection of CCD spectra of Aug. 31.30 UT with the Lick 3-m telescope 
reveals it is a type-Ib supernova a few weeks after maximum brightness.

SUPERNOVA 2008fe IN UGC 9578
Discovery by Stanilslav Korotkiy et. al., Kazan State University of a 
possible supernova (CBET 1485):
