V = 8.9;  Size 8

17.5": 15 stars mag 12-14 and two mag 9 stars in a 5'x2' group, very elongated 
N-S.  The two mag 9 stars bracket the group at the N (mag 8.9 SAO 38098) and S 
ends.  Not rich but stands out reasonably well at low power as the stars form a 
rough curving "S" asterism.  Two additional mag 9/10 stars are 3' and 5' W of 
SAO 38098 but do not appear part of the cluster.
