Dear all, I made a second attempt tonight to image the field near HX Peg, using the 0.35-m f/6.3 telescope of CBA Belgium Observatory. Mid-time of observation : 0h35m UT on Sep 21, 2003. I collected 10 unfiltered CCD images of 60 sec each and stacked them to obtain 1 final "deep" image. The limiting mag of the resulting image is above mag 18.0 (red), but again there is no indication of a new object near the indicated position. Looking forward to hearing about further observations obtained with big instruments ...

The transient object whose information is given on my website http://vsnet2.hawaii.edu/~linnolt/HXPegtransient.html is apparently fading rapidly, as evidenced by the nature of the light curve ending at Sep 20 11:28UT and the negative observations to V=16 or 17 at 18UT. Anyone with large aperture and can get down faint is requested to observe this region ASAP! Thank you very much, Mike Linnolt On Sat, 20 Sep 2003, Michael Koppelman wrote: > Hmm, quite a mystery.
