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

Historical observations

William Herschel (c.1784)

In the Appendix to the 1912 'Scientific Papers of Sir William Herschel' this object is described as "1784, March 11. A fine, bright nebula, much brighter in the middle than at the extremes, of a pretty considerable extent, perhaps 3' or 4' or more. The middle seems to be of the magnitude of 3 or 4 stars joined together, but not exactly round; from the brightest part of it there is a sudden transition to the nebulous part, so that I should call it cometic."

This is the major condensation in the Leo I cloud; it is centred on a dense core (3°x1.5°) including NGC 3351 (M95), NGC 3368 (M96), 3377 3377A 3379 3384 and NGC 3412.

Modern observations

Walter Scott Houston

writes: "They [M95 and M96] are not breathtaking to say the least, and for small telescope users a good description is that they are bright enough to see. M95 is a barred spiral. Most amateur telescopes will show a 10.5 mag central core. Close scrutiny will reveal it to be a gently squared-off circle."

Hartung, E.J. (1968) Astron.Obj.South.Tel

Notes: "10.5cm shows a rather faint small hazy spot. With 30cm it is a bright symmetrical round haze nearly 3' across in a field of a few scattered stars; the outer parts are very faint and there is a small bright nucleus."

Tom Lorenzin

Lorenzin, in the electronic version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "9.7M; 4' diameter; medium bright with stellar nucleus; barred spiral with faint bar visible with larger aperture; see photo at HAG-48; 40' W of brighter M-96; !good supernova prospect!."

Ware, Donald J

:" Round, about 3' in diameter with a bright core surrounded by a faint halo. This is a barred spiral."

Koornlandskloof

12-inch f5 (EP: 26mm SW, 20mm UW, 7mm UW)

Conditions: The most clear sky possible. Dark moon and stars magnitude 6 and fainter are visible with the naked eye. Excellent clean sky, limited star flickering and brilliant objects. Limiting Magnitude: 6.2.

Barred Spiral Galaxy located in Leo. Bright, well defined. Fairly low surface brightness. This galaxy has an oval shape with the outer regions just resolvable with a slight dust lane. The galactic nucleus has a very bright central bulge. No stars near the galaxy.
