The telescope detection performance was highly improved this night by the use of a 50 cm black baffle in front of the telescope, magnitude 19.2 was reached after a 10 minute exposure (street light at 40° form the object !!). Telescope baffling is neglected so often by users... it can help to gain magnitudes at a very low cost price... try it, it will pay off !!
This image was not flat field out, only by synthetic flat (raw images are so flat anyway)...

The Sn is too close to GSC2282-0930 (Mg 11.8), cannot be resolved...

SN possible candidates ? How to be sure ?
Image taken by R.CHASSAGNE, 09/02/2000 - 20h01m25s Reunion Island, Lx200. The following image shows a potential SN closely to NGC7141. The "star" disappeared in the next image, why ?
Looking closely to the star and its neighbors, this one appears smaller than similar brightness stars, also vertical and horizontal trails are visible, indicating a cosmic ray event "coming" almost perpendicular to the CCD, from the top right of the image.
So, unfortunately this object is neither a SN nor a GRB.
