NGC 3982 & NGC 3998: Galaxy Group (Ursa Major) RA: 11h 56.5m / DEC: +55° 07'.5
Instrument: 10-inch Starfinder

NGC 3982 and NGC 3998 are among a group of four galaxies in the bowl of the Big Dipper. They are located 1.7 degrees north-northeast of 2.4 magnitude Phad. 3.3 magnitude Megrez shines as a beacon about 3 degrees to the northeast. The view in my 10-inch is impressive. NGC 3982 is an 11.0 magnitude 2' diameter spiral galaxy displaying a stellar core. NGC 3998, 23' to the north-northeast, is a 10.6 magnitude spiral. This SA-type galaxy is 3' in size with a stellar nucleus. NGCs 3972 and 3990, 12.3 and 12.5 magnitude respectively, are also seen. NGC 3972 is 13' northwest of NGC 3882. It appears elongated, northwest-to-southeast, over a 2'x1' area. NGC 3990, 3' west of NGC 3998, looks like a 1' diameter eraser mark on the sky.
