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

Tom Lorenzin

Lorenzin, in the e-version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "11.4M; 2' diameter; round and bright with brighter center but non-stellar nucleus; !good supernova prospect!; SP GAL N4606 (12M; 2.8' x 1.5' extent) 22' to NW is overlain with 13M stars."

Observing site: Pinnacles overlook

Telescope: C-8

[12h 42m 0s, 11 39m 0s] AKA M 59. Like a fuzzy star. Small but bright. I suspected it was a Seyfert, Burnham notes it is a massive elliptical, but considerably smaller than the milky way.
