Located a short distance from zeta Ori. Not visible to me naked-eye, but clearly
visible in the same finder field. A 4 star system, with a birght primary, somewhat 
fainter second member, and 2 very faint stars. A low power it is apparent that
this is a multiple, and the 3 brightest are split at 48x. It took 120x to split 
the fourth member. No color, other than white, noticable for any of them.
