I went to the northwest hills of Conn. for our annual messier marathon. M81 galaxy had a bright central core. the outer areas of the nearly face on galaxy showed very well in the 20" dob one of the viewers brought.
Epsilon UMa (Alioth) (Star, in Ursa Major)

While getting a few last glimpses in 03/2001 of Orion now coming around to the south westerly portion of my sky ending the winter, I looked over my house rooftop and directly above me spotted Ursa major trying to let me know that spring was coming around and it was time to forget about my long love for orion. I got a good glimpse with my naked eye to make me ship make sure I gave all the stars a good glimpse. I was particularly interested in the double that supposedly hides in the center star in the handle. This wasnt really discernable as you are faked into thinking that 28601 just off to the side of Alioth is part of the double. But what is actually the double is much closer star to the 1.7 in the handle. None the less I was able to traverse each one of the stars clearly. Later in April I hope to catch the spoons treasures which range in magnitude of 6.7 to 12. This constellation was a clear cut gem and harold in the spring sky.
NGC3184 (Galaxy, in Ursa Major, Est. RaDec 10h18.3m, +41d25')
Observer: Dave Mitsky (e-mail: djm28@psu.edu)
Instrument: 17-inch equatorial reflector Location: Harrisburg, PA, USA
Light pollution: moderate Transparency: poor Seeing: fair
Time: Sat Jun 9 03:24:00 2001 UT Obs. no.: 556
On Sunday night I located the SAB(rs)cbII-III spiral galaxy NGC 3184, the penultimate object of my Herschel 400 observing program. Although the skies were far from transparent and NGC 3184's position was not ideal at the time, I was able to make out a very dim and diffuse amorphous object. No real detail was visible. NGC 3184 is listed at 9.8 in the NSOG (9.6 in the H400 manual) but has a very low surface brightness of 14, which made using averted vision and jogging the telescope mandatory. This large (7.8'x7.2' in the NSOG, 5.6'x5.6' in the H400 manual) spiral is situated 1/2 degree west of Mu Ursae Majoris. An 11th magnitude field star is in close proximity to NGC 3184. Magnifications of 162 and 259x were used. The previous night at 03:25 UT I logged NGC 3655, a dim 11th magnitude elliptical H400 galaxy in Leo that lies north of M66. It was rather small and appeared circular and faint.
NGC3631 (Galaxy, in Ursa Major, Est. RaDec 11h21m, 53d10')
Observer: Dave Mitsky (e-mail: djm28@psu.edu)
Instrument: 17-inch equatorial reflector Location: Harrisburg, PA, USA
Light pollution: moderate Transparency: poor Seeing: fair
Time: Thu Apr 19 03:01:00 2001 UT Obs. no.: 548
Date: 2001/4/18-19Conditions: Seeing - 6/10, Transparency - 4/10, Limiting magnitude - ~5.0, Dome Temperature - 39 degrees FahrenheitLocation: ASH Naylor Observatory (http://www.astrohbg.org) located 2miles northwest of Lewisberry, PATelescopes: 5" f/5 finderscope & 17" f/15 equatorially mounted classical CassegrainOculars (17"): 55mm University Optics Ploessl (118x), 45mm U.O. Ploessl (144x), 32mm U.O. Koenig-II (202x) & 25mm U.O. MK-70 (259x)After viewing C/2001 A2 (LINEAR) and other celestial objects clouds were beginning to grow troublesome in the south and west so I set the French Dome shutter for an overhead view. M97 (118x) was quite faint in the less than transparent sky. I had to play hide and seek with clouds for a bit but eventually (at 03:01 UT) I tracked down another new Herschel 400 galaxy, one that is located about 2 degrees southeast of M97 at 11h21m, 53d10'. NGC 3631 (118, 144, 202, and 259x) is a moderately large star city of the SA(s)c I-II variety. According to the NSOG this face-on 10.4 magnitude spiral galaxy is 5.5'x4.6' in size and has a surface brightness of 13.8 magnitude. It was dimmer than it should have been due to the poor transparency and local light pollution but I could see a circular glow with a slightly brighter core. As with the comet the 32mm U.O. Koenig-II provided the best view.
NGC3310 (Galaxy, in Ursa Major, Est. RaDec 10h35.7m, +53d30')
Observer: Dave Mitsky (e-mail: djm28@psu.edu)

Light pollution: moderate Transparency: good Seeing: good
Time: Tue Jun 20 02:27:00 2000 UT Obs. no.: 531
NGC 3310 is an irregular galaxy that lies to the southwest of beta Ursae Majoris and just to the south of a sixth magnitude field star (page 46, Uranometria 2000.0). A crooked line of 3 relatively faint field stars is located to the immediate south of NGC 3310. This Herschel 400 galaxy appeared circular, with a somewhat brighter nuclear region, and was seen without difficulty. The Herschel 400 manual lists NGC 3310 as being somewhat brighter (10.1 magnitude) and larger (4.0'x3.0') than does _The Night Sky Observer's Guide_ (10.8 magnitude, 3.5'x3.2').

NGC 5631 is a small (0.7'x0.7' AL) but obviously non-stellar 11.4 magnitude spiral galaxy. I used 118, 202, and 259x on this object, which is found in the vicinity of M101. NGC 5631 was circular and had a somewhat bright nucleus. It formed a triangle with two 12th magnitude field stars to the north.

I have done a lot of observing so far this year and have been remiss in sending reports to AAOL on the most interesting of the celestial objects that I have viewed. I will post some of these in the near future but there is visible currently an object that demands attention. The type Ia peculiar supernova SN1999by is located in the northern half of NGC 2841, a bright (9.3 magnitude) Herschel 400 spiral galaxy located about two degrees southwest of Theta Ursae Majoris. The supernova is just to the southeast of an embedded 11.1 magnitude field star and was slightly brighter than two nearby 13th magnitude (13.5 and 13.8 magnitude) field stars. I used magnifications of 118, 202, 259, and 381x to observe SN1999by.

A nice, small, rather elognated galaxy easily in the same field of view as M97. M97 showed up a lot easier, although the visual magnitude is 12.0 (M108 is 10.7).

Time: Thu Apr 23 01:55:00 1998 UT Obs. no.: 327
Despite the terrible transparency, I was able to see the recently discovered supernova SN1998aq on Wednesday evening. This exploding star is located in NGC 3982, an 11th magnitude H400 spiral galaxy located in the "bowl" of the Big Dipper, about 1.5 degrees north of Gamma Ursae Majoris. Supernova 1998aq formed a triangle with 2 nearby faint field stars. It was fainter than either of the field stars. According to the IAUC 6875, SN1998aq is located 18" west and 7" north of the center of NGC 3982. NGC 3982 appeared as a very dim circular glow. It was the first night of the spring Astronomical Society of Harrisburg observational astronomy class at the Naylor Observatory and after later showing the class the supernova I trained the 17" on M3, Algieba, Castor, and M35. The poor observing conditions limited what I could show the class, of course.

Time: Fri Apr 3 02:12:00 1998 UT Obs. no.: 317
After observing Supernova 1998S in NGC 3877 once again and determining that it had dimmed since my last observation on 3/31, I moved on to other galaxies in the neighborhood of NGC 3877 in Ursa Major. I logged 5 new galaxies, 4 of them H400 objects. NGC 4026 is a 10.7 magnitude elliptical galaxy which appeared as circular and small with a "stellar" nucleus. The other galaxies were NGC 3953, NGC 3998, NGC 3990, and NGC 3982. Earlier that evening I observed M64, M97, M108, and M109.

On 3/17 UT I observed the recently discovered supernova 1998S located in NGC 3877, an 11th magnitude spiral edge-on galaxy near Chi Ursa Majoris. 1998S was listed at 13.5 magnitude and was said to be offset 16" west and 46" south of NGC 3877's nucleus in the IAU CBAT circular #6829. It is believed to be a type-II supernova. I also observed M34, Stock 2, the Double Cluster, NGC 2451, NGC 2362, h3945, M93, M42, Sigma Orionis, Struve 761, M66, M65, and NGC 3628.

Playing tag with high clouds drifting through from the S, I shifted my telescope to the other side of the yard so I could point it at the N sky. M81 was swept up after referring to the small chart of UMa in the Audubon Field Guide to the Night Sky. A big, bright, fuzzy oval patch elongated N-S at 38x. A fairly large, condensed center.
M40 (Multiple Star, in Ursa Major)

Time: Wed Dec 3 05:30:00 1997 UT Obs. no.: 265
At last! After many failed attempts to observe M40 with 7x35 binoculars during the summer and fall, my new 10x50's finally brought it into view. It popped in and out, but I could hold it for many seconds at a time. M40 is listed as mag. 9, which was near the limit of what I could see this night. M40 is the 63rd Messier object I've observed with binoculars since June.

Time: Sat Jun 7 10:00:00 1997 UT Obs. no.: 148
This was a strange one. I took a photo of Ursa Major (2 min. using 800 ASA Fuji Super G film) and when I got it developed and went to my Skt Atlas 2000.0 to pinpoint the stars, I picked up two strange blobs of light. After checking another sky atlas, I realized that I picked up two very faint galaxies on film. NGC 3898 and NGC 3888 were a complete surpirse. The sky gods were very kind to me that night.
