Corwin's Notes

=====

NGC 6172 = IC 1213.  Stephan's position is 10 minutes of time too large due to
a misprint in his paper in AN 2661.  The position for his comparison star is 
correctly given, however, and identifies it as SAO 141069.  Once the 
correction is made, it's clear that N6172 is IC 1213.  RC3 is correct for a 
change.  

See UGC 3840 in the "notngc" file for more on Stephan's observations.

Steve's Notes

=====

NGC 6172

17.5" (7/24/95): fairly faint, small, round, 30" diameter.  Moderate concentration with a very small bright core which stands out well surrounded by a small halo.  Preceded by three mag 13 and 14 stars within 3'.  Located 9' NW of a mag 10 star and 11' NE of a similar star. Incorrectly listed as nonexistent in RNGC.  Identified as IC 1213 in UGC, MCG.
