 Wide pair of different magnitudes. The WDS lists the faint secondary as a close pair of equally faint stars, 0.2 at 013 deg 1991 measure. I found the secondary distinctly elongated, but at a 090-270 PA about 0.5 sec, will need a night of fine seeing to re-observe this one. Primary measurement, 32.88 sec at 143.5 deg PA.
