A wide double of two pale yellow stars separated by about 2' roughly north and south, m Per is the northern star while the southern companion HD 28693 is about ½ magnitude fainter, 45' south of NGC 1582
Interestingly GAIA data shows both stars are relatively nearby, with parallax of 16.37 for m Per and 13.59 for HD 28693, the two have radically different proper motions with HD 28693 exhibiting high proper motion of 24.25mas/yr in ra and -59.91mas/yr in dec, while m Per is moving at a more sedate 5.37mas/yr in ra and 5.31mas/yr in dec

A wide double star, in the left ancle of Perseus, with several small Stars in the field, of which a remarkable one of the llth magnitude is to the np of A, and seems to have escaped the eye of ♅.
A and B are both of the 8th magnitude [HD 28704 and HD 28693], and white; being Piazzi's 101 and 104 of Hora iv. The object is 99 ♅. VI., and with a reduction from the Palermo Catalogue may be thus registered:♅. Pos. 198°09' Dist. 96".42 Ep. 1783.66It was next measured by ♅. and S., with these results:
P. 198°30' 116".00 1800.00Pos. 198°52' Dist. 110".19 Ep. 1821.91whence an extraordinary change of distance was shown. Subsequent measures, however, indicate some error in ♅.'s register. It will be found nearly in mid-distance of a line run from α Persei to β Tauri, at about 10° from the former.
