(1) CH UMa was seen in outburst. Magnitude uncertain due to
poor sequence and cloud interference.

(2) An object was seen at the correct location. It was seen
near threshold (due to a rather poor seeing and bright sky
background) and was clearly (about 4 steps) fainter than
GSC 1621-1322 (V = 13.41).

                                    Yours sincerely,
                                    Bjorn H. Granslo
