SDSS J230351.64
Gary Poyner, Birmingham, England, reports that Ian Miller has detected a 
rare outburst of this Recurrent 0bjects Programme (ROP) star, which he 
was able to confirm:

2006 Aug 29.953    14.5C     Miller
      Aug 30.068    14.2v     Poyner

Gary adds that this star was added to the ROP in 2003, since when there 
have been no outbursts reported.  Taichi Kato comments on VSNET alert 
8995...
So, the amplitude of the current outburst is (at least) 4.9 mag. 
Although this is not well above usual thresholds of SU UMa-type 
superoutbursts, the literature description would make it a suitable 
target for time-resolved photometry. The reported "low mass-transfer" 
for such a period (100 min) is relatively rare; from the lack of 
prominent emission from the hot spot in quiescence, the object may 
resemble rather unusual dwarf novae like HT Cas.

COMET 29P/SCHWASSMANN-WACHMANN
Giovanni Sostero and Ernest Guido, Italy, report that their images of 
this comet for 2006 August 28 and August 30 show the comet in outburst 
on the latter. The Afrho parameter (measured within a radius of almost 
25,000 Km at the comet distance) passed from 1,600 cm (Aug. 28.41) up to 
10,000 cm (Aug. 30.39) --> ~6.5 fold increase.

Probably in the next few days we will witness the development of the 
classic asymmetric coma.

2006, Aug. 28.41, mag=15.8, coma diameter +0'.4 (E. Guido and G. 
Sostero, remotely near Mayhill, NM, 0.25-m reflector + CCD + Cousins R).
2006, Aug. 30.39, mag=14.2, coma diameter +0'.4 (E. Guido and G. 
Sostero, remotely near Mayhill, NM, 0.25-m reflector + CCD + Cousins R). 
The central condensation is bright and starlike.
