Special Notice #190: Probable Nova in Sagittarius [V5585 Sgr]

January 24, 2010: Further to CBET 2140 (D.W.E. Green, editor), a probably nova has been discovered in Sagittarius by J. Seach (Chatsworth Is., NSW, Australia). The object was discovered by Seach on 2010 January 20.22 UT (JD 2455216.72) at a magnitude of approximately 8.5 using a DSLR with 50-mm f/1.4 lens and orange filter, at coordinates RA: 18:07:26 , Dec: -29:01:00. Nothing was visible at this location in a prior image taken 2009 November 15.89 to a limit of mag 11.5. The object has since been confirmed by several observers: W.

Special Notice #195: Nova Oph 2010 No. 2 [V2674 Oph]

February 20, 2010: Central Bureau for Astronomical Telegrams CBET 2176 (Daniel W. E. Green, ed.) announces the discovery by Hideo Nishimura, Miyawaki, Kakegawa, Shizuoka-ken, Japan, of a probable nova (confirmed in CBET 2179). Discovery was Feb. 18.845 UT at magnitude 9.4, on two 13-s frames using a Minolta 120-mm f/3.5 lens and a Canon EOS 5D Digital camera mounted on a Takahashi EM100 equatorial telescope.

Special Notice #196: Possible Nova in Scorpius - N Sco 2010 [V1310 Sco]

February 23, 2010: Central Bureau for Astronomical Telegrams CBET 2183 (Daniel W. E. Green, ed.) announces the discovery by Koichi Nishiyama, Kurume, Fukuoka-ken, Japan; and Fujio Kabashima, Miyaki-cho, Saga-ken, Japan, of a possible nova in Scorpius at magnitude 10.5 on two 40-s unfiltered CCD frames (limiting magnitude 12.7) taken around Feb. 20.857 UT. They confirmed the new object at magnitude 10.3 on unfiltered CCD frames (limiting magnitude 17.4-17.6) taken around Feb. 21.832 and magnitude 10.7 on Feb.

Special Notice #198: Possible Outburst of GK Per

March 9, 2010: The old nova (1901) and x-ray source GK Per may be going into outburst. Reports beginning late on 2010 March 6 UT show it brightening from its minimum visual magnitude of about 13.1 to 12.3-12.4.
