Seeing: 7 Transparency: 6 Moon: 0%
Yellow, the 12th magnitude star 150" south is listed as a companion, three other 12th magnitude stars at the same distance are visible to the southest, east, and northeast
WDS lists the B component as 11th magnitude 147" @ 197°, this star is noted as double itself as BC: 10/11th mag 1.9" @ 302° (some discrepancy in magnitudes here?) This pair is not cataloged in SIMBAD beyond the WDS entry and not visible in survey imagery due to the glare of Sadr.
