Spiral Galaxy NGC 3079
A 10 minute exposure with an SBIG ST-9E CCD camera taken thru our 20 inch F/8.1 telescope taken on 5/16/01 at 4:00 UT.

Supernova 2001 ci:

Discovered April 17th, 2001, by the LOTOSS supernova search group.

Follow this Link to a NASA Web site on supernovas. It has a very nice animation and a description of what these objects are.


Spiral Galaxy NGC 3810:

Dreyer's description in the New General Catalog (NGC):

"Very bright, large, moderately extended 135°."

Quote from The Deep Sky Field Guide to Uranometria 2000:

"Bright, peanut-shaped bar: 1.4 arc min x 0.3 arc min with dark lanes on one side. Almost edge-on and probably similar to NGC 4631.

NGC 3079 in the constellation of Ursa Major is a peculiar nearly edge-on Spiral Galaxy with a violent bipolar outflow of gas from the nucleus, a "galactic superwind" (Filippenko & Sargent 1992). These "superwinds" (Heckman, Armus, & Miley 1990) are thought to arise from the collective energy deposition and expulsion of matter from massive stars and supernovae in "starburst" systems. The center of NGC 3079 also harbors an Active Galactic Nucleus (black hole?). It has large amounts of dust and dark molecular clouds irregularly distributed throughout its disk and reddening toward its nucleus. This "starburst galaxy" is also an infrared, radio, and X-ray source.

Based on the published red shift, (and a Hubble Constant of 62 Km/sec per Mpc) a rough distance estimate for NGC 3079 is 59 million light years, with a diameter of about 136,000 light years.
