Extra remarks:
(1) AG Pegasi. I refer to Erwin van Ballegoij's report on a
possible brightening to mag. 8.0 on Oct 1 UT [vsnet-obs 36153].
My observation from Oct. 2.85 UT: AG Peg appeared 0.5 mag. fainter
than TYC 1130-0061 (V=8.68) and 0.3 mag. brighter than TYC
1130-1034 (V=9.54); class 1 observation. It looks normal to me and
I can thus not confirm any brightening of this star.

(2) Observation of V2275 Cygni (Nova Cygni 2001 No. 2) from
Oct. 2.859 UT: T-5; U+2 (class 2 obs.). Comparison stars (Henden
CCD-V): T= GSC 3596-0168 (V=11.70), U = GSC 3592-0767 (V=12.39).

                                   Yours sincerely,
                                   Bjorn H. Granslo
