Summary description: eF, * 13 nr
NGC 2957 is the brighter of a pair of galaxies, or perhaps the pair itself.
JH describes it only as "eF; has a * 13 m near," and his RA is one minute of
time too small. But his object is clearly identified by the star, as well as
its proximity to NGC 2963 which shares the RA error.
The fainter galaxy is Markarian 121, so has received somewhat more attention
than its brighter companion. This probably accounts for the RC2 designation
"N2957A" for the fainter object, and "N2957B" for the brighter.
17.5" (4/4/92): faint, very small, round, broad concentration. A mag 14 star is 25" off the SW edge and 40" from the center. Forms a pair with NGC 2963 2.8' ESE. The RNGC incorrectly equates NGC 2957 with NGC 2963 so both are plotted as one object on the U2000.
