August 7, 2015: Further to AAVSO Alert Notice 525, we are entering the critical period of observations for KIC 02856960. Time series observations are urgently requested for this eclipsing binary beginning immediately (2015 August 07, JD 2457242) and continuing for the next five days, through the end of 2015 August 12.
August 4, 2015: Dr. Gregory Sivakoff (U. of Alberta) has requested optical monitoring of the galactic microquasar V4641 Sgr beginning immediately, and continuing for the next 120 days, or until it is no longer observable from your location.
February 13, 20115: Patrick Schmeer (SPK, Bischmisheim, Germany) reports the announcement on the CBAT Transient Object Confirmation Page (TOCP) of the discovery of a bright transient in Sgr on 2015 February 12.852 at an unfiltered magnitude of 10.9 by K. Nishiyama, using a 105-mm f/4 camera lens with an SBIG STL6303E CCD camera. Nishiyama notes nothing is present on a previous image from 2015 February 02.887. The transient has been independently confirmed with two pre-discovery images: by H.
December 6, 2013: Observer Carlo Gualdoni reports via the cvnet-outburst mailing list that the WZ Sge-type dwarf nova AL Comae is in outburst, with a magnitude of V=12.74 on 2013 December 6.185 (JD 2456633.1185). Gary Poyner notes on the BAAVSS mailing list that this is the first observed outburst of AL Com since October 2007. Both visual observations and CCD time series are encouraged.
September 10, 2011: Dr. Gregory Sivakoff (U. of Alberta) requests observations of the X-ray binary star MAXI J1836-194 as part of the JACPOT collaboration studying stellar radio jets from compact binaries. There is no predetermined duration for this campaign, but observations are requested now to coincide with ongoing X-ray and radio observations.
Nick Brown in vsnet-alert 13560 posts about a possible new nova from his photographic survey:
"The star appears at mag 10.2 photographic, on 2 films taken on August 4.73UT using a 135F2 cannon lens and tmax 400 film.unfiltered. No object is present on film taken on july 5.85UT down to 11.7pg. No previous variable stars are reported at this near position."
