* V844 Herculis. This UGSU type dwarf nova is apparently fading from its
   recent 'supermaximum'. B. Sumner's sequence (with photometry by Henden)
   is at ftp://ftp.aavso.org/public/calib/sumner/v844her.seq .
* AX Persei. Comparison stars for this symbiotic variable (V-magnitudes
   from TASS-4): F = 11.21 [TYC 3675-2376]; G = 11.79 [TYC 3671-1479].
* BF Cygni. This symbiotic star is in outburst. Comparison stars (V-mags.
   by Tycho-2 w/Bessell and Skiff): B = 9.45 [BD +29 3580 = TYC 2136-0219];
   D = 10.52 [BD +29 3586 = TYC 2137-0298]. B. Skiff's photometry is at
   ftp://ftp.lowell.edu/pub/bas/varseq/bfcyg.seq .
