TAV 1831+19 1991/68 10.8-(12 14 Aug 1991 TA EC-565 Her 73 (58) Bright in May 1989 but faint in May 1991. Identified on TVMPSA and Atlas Stellarum but no catalogue identifications. Guide Star Catalog reveals two "non-stellar" objects 5" apart at this position so object's identity and nature uncertain! Photograph by M. Mobberley reported on TA EC-574 used to make (c) chart, extend sequence to 15.4, and confirm the N-S pair separated by 7". Visual work by G. Poyner and photography by N. James show that the northern component varies and report results on TA EC-654. Photographs showing variation appear on inside back cover of The Astronomer for September 1992. Additional magnitude estimates made in August/September 1993 confirm that the variable star is the northern component and further details appear on TA-EC 783. 2105+23 1991/78 1 Sep 1991 Vul 62 Bright in mid-October 1990 and early August 1991.

Identified Per 51 as NSV 1528 = IRC+30079 = AFCRL 556 = IRAS 04123+3342. Wilson and Barrett (1972) fail to detect OH maser. Vogt (1973) assigns spectral type M6 whereas Stephenson (1986) gives Sp M6-7. 0257+57 1991/99 15 Oct 1991 Per 21(22) Bright in mid-October 1991 but faint in December 1988 and February 1989.
