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

Together with NGC 5929 listed as No. 90 in Arp's "Atlas of Peculiar Galaxies" (Astrophysical Journal Supplement, vol. 14, 1966.) He remarks "absorption lanes around companion."

Sulentic & Tifft (1973)

The RNGC (Sulentic and Tifft 1973) notes that this is a 13.0 mag galaxy. Their coded description reads R,SLDIF,BM,CONTW/29.

Van den Bergh, S. (1961)

Modern observations

Steve Coe

Steve Coe, using a 13" f/5.6, notes: "Pretty faint, small, round and little brighter in the middle at 165X. These two galaxies (NGC 5929 and NGC 5930) form a contact pair that is elongated 2 X 1 in PA 45, somewhat like a figure 8."
