SUPERNOVA IN ANONYMOUS GALAXY
B. Szeidl, Konkoly Observatory, cables that M. Lovas has discovered
a supernova 8" west and 1" south of the nucleus of a galaxy
located at R.A. = 7h47m.0, Decl. = +73o27' (equinox 1950.0). On Nov. 2 the
photographic magnitude was 18.0.
NEW GALAXIES OF THE LOCAL GROUP
Kowal, Lo and Sargent, Hale Observatories, report the discovery
of three dwarf galaxies that are probably new members of the
local group. They were found on Kodak IIIa-J plates obtained with
the 122-cm Schmidt telescope at Palomar during Oct. 25-29. The objects
are very faintly visible on the blue Palomar Sky Survey
prints. Information about LGS 1, 2 and 3, as well as about two
dwarf galaxies LGS 4 and 5 that are probably not in the local group,
is provided as follows:
Object R.A. (1950) Dec. Size Mag. Remarks
LGS 1 0 15.0 +22 13 1' x 1' 20 Extremely diffuse
LGS 2 0 26.6 +33 04 3 x 2 19 "
LGS 3 1 01.2 +21 37 2 x 2 18 Resolved; Mag. 21 stars
LGS 4 0 16.2 +30 13 1 x 1 18 Red
LGS 5 0 26.8 +27 41 1 x 1 20
SS 433
F. Ciatti, A. Mammano and A. Vittone, Asiago Astrophysical
Observatory, report that they are observing unusual changes in the
singular spectrum of SS 433 (cf. IAUC 3256, 3258). On Oct. 10 they
noted [Fe X] 6373 A and on Oct. 24 [Fe VII] 6085 A. A diffuse band
appeared around 5900 A on Nov. 5, and it was displaced toward
5890-5876 A on Nov. 6 and 7. On Nov. 10 and 11 the band separated into
two lines at 5876 and 5910 A, the latter being much the stronger.
