Warning: date(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected the timezone 'UTC' for now, but please set date.timezone to select your timezone. in /home/yivumoo/public_html/show_object.php on line 167

A few late-type spirals with fairly large diameters and consistent velocities stand out in Leo Minor in the foreground of more distant clouds ... [ see Table 4] cover an area 10°x5°. Two more (NGC 3344 and NGC 3510) 10° south of the group .. might be included as possible members."

(1975, Astrophysical Journal, 196, 313-328) includes this galaxy in the NGC 3184 Group. Members include NGC 3184, NGC 3198, NGC 3319 & NGC 3432.

Modern observations

Walter Scott Houston

Houston notes that this galaxy appears brighter to him that its catalogued value of 12.1. He has been able to see it with a 5-inch Moonwatch scope. It has been described as very diffuse with an 11th mag star on its northern edge, as seen in a 6-inch. There is a red 7th mag star 10' to the west.

Tom Lorenzin

Lorenzin, in the electronic version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "10.5M; 5.5' diameter; soft glow with no center condensation; Mu UMA in same wide field to W; bright star 6' WNW of core is 7M SAO 43270; !good supernova prospect!."
