Corwin's Notes
=====
NGC 2143. This is a cluster of pretty bright (V ~ 9 - 13) stars covering an
area about 12 arcmin by 10 arcmin across. While JH puts the center close to
the brightest star (SAO 113401), I make it (on the POSS1 print) about three
arcminutes to the west.
Brian Skiff puts the center (using the DSS) seven arcmin to the north, nearly
on the edge of the cluster. This must be a typo of some sort.
A curiosity: JH's original description contained the note, "... place of a *
10m in M." Somehow, this metamorphosed into "stars 10" in GC and NGC. This
may have led in part to RNGC's failure to find the cluster.
Steve's Notes
=====
NGC 2143
18" (11/6/04): at 73x this asterism is a large, scattered rectangular group, roughly 10'x6', and elongated N-S. On the west side is a N-S string of stars while the east side is dominated by three brighter mag 9.5-10.5 stars including mag 9.6 HD 41080. Off the two northern vertices of the main rectangle, strings of stars head NW and NE extending the diameter to at least 15'. This scattered group just stands out with 31 Nagler in a fairly rich field and appears to be an asterism. Listed as nonexistent in the RNGC.
