A striking trio of stars found a degree northeast of ο2 Ori, a white 6.1 magnitude promary flanked by fainter companions, a 7.6 magnitude HD 31764 40" northwest and a 9.8 magnitude BD+14 797 54" east
This appears to be a physically bound trio with parallax of 2.85/2.35/2.44mas for the A/B/C components in the Gaia DR2 data, proper motions are also consistent. WDS also lists a 13th magnitude 90" companion D to the trio, this star does not appear to be associated with a parallax of 1.31mas

A wide triple star, between the Bull's ear and Orion's arm; and nearly one-third of the distance from Aldebaran towards Betelgeuze, where it is also shewn by a line carried from Sirius through Bellatrix, and extended about 10° beyond.
A 7, white; B, which is No. 255 of Piazzi, 8, cerulean blue; and C 10, purple, with a minute star following it. This is a pretty though coarse object, forming a neat arc; and A and B were measured by H. and S. as 26 Bode Orionis, with results which may he thus placed with the conclusions obtained from the RAs and Decs. of the Palermitan Catalogue :P. Pos. 301°00' Dist. 44".30 Ep. 1800.00A slight movement in space is attributed to A of the following value:
