Corwin's Notes

===== NGC 2220. JH calls this "A poor, very coarsely scattered, but brilliant cluster of 8th class. Place of a star 8m = B 1222, the chief of cl." The star is SAO 217873 and is well off the center towards the southeastern edge of a clump of 7-8 stars. Roughly 15 arcmin to the northwest is a similar clump of 4-5 stars; I wonder if JH meant to include this as well. I've included positions for both clumps and the entire grouping in the table. In any event, the stars probably do not constitute a real cluster. We'll need to check their proper motions to be sure of that, however.

Steve's Notes

===== NGC 2220 24" (2/22/14): at 125x, this asterism is a scattered 20' field containing several bright stars. There are two groupings with the more prominent southeast group containing 8 brighter stars including mag 7.7 HD 44737, mag 8.4 HD 44665, mag 8.8 HD 44764, along with 4 mag 10-11 stars. These are scattered within an 8' region. A separate group is to the northwest, separated by a 7'-8' gap, which contains 4 mag 9.5-10 stars. Visually this appears to be a random grouping, though the number of bright stars is striking. ESO 255-005 off the east side of the asterism was not seen. Viewed at an elevation of only 8¡.
