Despite the weather forecasts a clear night materialized on Monday and my goal of viewing this recent supernova was realized. Here's a slightly modified version of the observing log that I sent to netastrocatalog this morning.Observer: Dave MitskyYour skills: Advanced (many years)Date/time of observation: 2003/4/1 6:15 UTLocation of site: ASH Naylor Observatory (40.1 degrees N, 76.9 degrees W, Elevation 190 meters)Site classification: ExurbanSky darkness: ~5.0 <Limiting magnitude>Seeing: 6 <1-10 Seeing Scale (10 best)>Moon presence: None - moon not in skyInstrument: 17" f/15 classical Cassegrain equatorial mountMagnifications: 162, 202, and 259xFilter(s): NoneObject(s): SN 2003cg, NGC 3169, NGC 3166Category: Extragalactic starClass: Subluminous type Ia supernovaConstellation: SextansMagnitude: ~14.0 Position: 10h14m, +03d28'Description:This recently discovered type Ia supernova was visible with averted vision. Its parent galaxy NGC 3169 and nearby NGC 3166, both Herschel 400 spiral galaxies, were easily seen. SN 2003cg was located within the glow of NGC 3169 - see http://messier45.com/cgi-bin/h400/i.cgi?n=3169&d=GX - making a sighting somewhat difficult. The supernova is situated 14" east and5" north of NGC 3169's nucleus. An 11.3 magnitude field star lies almost due east.

NGC3115 (Galaxy, in Sextans)
Observer: John Callender (e-mail: jbc@west.net, web: http://www.west.net/~jbc/)

Inspired by a navigational discussion with my wife Linda, I set out to explore Sextans. The only object in the constellation to get a detailed Burnham's description was NGC 3115, the "Spindle Galaxy." It's described there as being an odd cross between an elongated elliptical and an edge-on spiral, having an extended axis that goes beyond the elliptical part, but lacking the central dust lane that would be expected in an edge-on spiral. In keeping with the night's navigational theme, it took a neat bit of piloting to reach the galaxy, star hopping with my 38X Plossl eyepiece through a star-poor region with only the Tirion Sky Atlas to guide me. The galaxy itself was a bright, obvious smudge, elongated NE-SW, with a central core apparent when I switched to high power (244X).
