AAVSO Special Notice

Special Notice #26: Possible Minor Outburst of 0324+43 GK Persei

December 15, 2006

Coordinates: 03:31:11.82 +43:54:16.8 (2000.0)

Recent observations of the old nova intermediate polar magnetic catclysmic variable GK Per (Nova Per 1901) show the star brighter than minimum. However, it is too early to tell if an outburst is underway.

Special Notice #25: Variable Star in Leo - 1016+24 VAR LEO 06

November 20, 2006

Daniel W. E. Green, Central Bureau for Astronomical Telegrams, reports (Central Bureau Electronic Telegram 746) that "E. J. Christensen, Lunar and Planetary Laboratory, University of Arizona, reports his discovery of an apparent high-amplitude variable star on unfiltered CCD images obtained in the course of the Catalina Sky Survey, the position of the variable given as

R.A. = 10h 21m 46.42s, Decl. = +23o 49' 26.2" (equinox 2000.0)

Special Notice #24: Outburst of EG Aqr

November 8, 2006

Rod Stubbings has detected a bright outburst of the dwarf nova EG Aqr. This has been confirmed by Hiroyuki Maehara of the VSOLJ, at magnitude V=13.08. This object has not been in outburst in recent history (last outburst I see is 1951?), so monitoring and V-band time series are encouraged. Good charts and photometric sequence information is on the AAVSO website.

November 6, 2006

Daniel W. E. Green, Central Bureau for Astronomical Telegrams, reports (Central Bureau Electronic Telegram 721) that N. Lee and W. Li report the Lick Observatory Supernova Search (LOSS) discovery of an apparent supernova on unfiltered KAIT images taken on Oct. 22.56 UT (CCD magnitude 12.7) and Nov. 5.50 UT (magnitude 13.2).

SN 2006mq is located 16.6" east and 124.3" south of the center of ESO 494-G26, at:

R.A. = 08h 06m 12.39s, Decl. = -27o 33' 45.4" (2000.0)

Special Notice #22: Bright New Variable in Cassiopeia

October 31, 2006

Daniel W. E. Green, Central Bureau for Astronomical Telegrams, reports (Central Bureau Electronic Telegram 711) that S. Nakano, Sumoto, Japan, reports the discovery of a brightening star in Cassiopeia by Akihiko Tago, Ayabe, Tsuyama, Okayama-ken, Japan. Unfiltered CCD observations by Tago include October 25.538 UT, 10.7; 27.409, 10.5; 30.411, 8.8; 31.469, 7.5. Tago used a 70-mm f/3.2 lens and a Canon EOS 20Da digital camera (limiting magnitude 12).

magnitude: ~R magnitude ~14.9 (unfiltered CCD, approx. R magnitude)

date: Oct. 20.0 UT (4 images taken with 60-cm instrument)

Special Notice #1: Exoplanet Transit Campaign for Southern Hemisphere

December 8, 2005

Dr. Greg Laughlin (UCO Lick Observatory/ and Dr. David Blank (James Cook University) are conducting a photometric monitoring campaign for exoplanet transits of HD 13445. The windows for possible transit are:

December 11 20:51 - December 12 05:00 (UT)

December 27 14:58 - December 27 23:36 (UT)

HD 1334 is located at RA 02:10:14.4 and Dec. -50:50:0.5 (J2000).

Special Notice #417: CH Cygni B and V photometry urgently requested

June 3, 2016: Dr. Margarita Karovska (Harvard-Smithosonian Center for Astrophysics) is urgently requesting B and V photometry of the symbiotic variable CH Cyg from now until at least the end of August. Observations made twice a week are sufficient; time series observations are not needed. Spectroscopy would also be very welcome and appreciated.
