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 electronic version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "11.4M; 1.6' x 0.9' extent; stellar nucleus; 14M SP GAL N3377a (1' diameter) is a few minutes to NE; very, very faint; both are !good supernova prospects! SP GAL N3367 is 20' to SW."

Telescope: C-11

[10h 47m 42s, 13 59m 0s] Bright center, elongated envelope. Lovely galaxy. Spiral, Sb or Sc? (E5: Burnham!)

Sky Conditions:The fainter parts of the Milky Way are barely visible.Haziness only visible on the horizon.Atmosphere stable with little interference.

Instrument:12-inch Dobsonian.

This galaxy's circular like shape is seen as a grayish smudge of faint light and is unimpressive with no detailed like structure.This galaxy measures 3.3'* 1.1'.Right from the nucleus of this galaxy the light of this galaxy grows brighter compared to the far outskirts of this galaxy.
