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

Modern observations

Bahr-Vollrath, Gerd (1992)

Gerd Bahr-Vollrath (Noosa Heads, Queensland, Australia) observing with an 8-inch f/12 SCT, writes in The Webb Society Nebulae and Clusters Section Report No. 10, July 1992: "One of the many faint and challending galaxy clusters in Centaurus. All of these galaxies were at the threshold of visibility, and some may even have been a product of my imagination. The galaxies appeared as very indistinct diffuse glows, barely brighter than the background sky. Definitely a challenge for 20-cm telescopes."
