Nova in Sagittarius
This is an AstroAlert from Sky & Telescope.
A fairly bright nova has been discovered by Japanese observers Koichi Nishiyama (from Kurume) and Fujio Kabashima (Miyaki). They made their find on July 7, 2012, using a 105-mm f/4 camera lens and CCD, describing the nova as magnitude 7.8. It is located in Sagittarius roughly between the "lid" and "spout" of the Teapot stars, at right ascension 18h 20.5m, declination -27° 44' (equinox 2000.0). A number of other observers in Japan have made confirming sightings.
The American Association of Variable Star Observers (AAVSO) is requesting observations of this nova. The AAVSO collects magnitude determinations by skilled observers to aid in the study of novae and other variable stars, and their site offers guidance on the techniques involved.
