Part of physical binary system WDS J23100+5507 = NSN 11
Binary star designations are missing from SIMBAD.
While WDS did not explicitly assign A and B components, the magnitudes
are given as 15.8 & 15.9, sep=6.0" and PA=70 deg. Given the Gaia DR2
astrometry and SIMBAD cross-IDs, this unambiguously leads to the
primary being G 233-42 and the secondary being LSPM J2309+5506E.
WDS J23100+5507A = Gaia DR2 1996725077535282944 = G 233-42 (G=14.01)
WDS J23100+5507B = Gaia DR2 1996725077535283200 = LSPM J2309+5506E (G=15.61)
