December 18, 2013: Further to AAVSO Alert Notice 493, Dr. Hans Moritz Guenther (Harvard-Smithsonian Center for Astrophysics) has been given the precise times of the Chandra X-ray observations to be made of the T Tauri star BP Tau:
year:day:hour:min (in UT):
2013:356:22:52-2013:357:10:00 = 2013 Dec 22 22:52 through Dec 23 10:00 UT
2013:359:14:46-2013:360:06:06 = 2013 Dec 25 14:46 through Dec 26 06:06 UT
2013:361:17:58-2013:362:16:18 = 2013 Dec 27 17:58 through Dec 28 16:18 UT
The AAVSOnet Epoch Photometry Database comprises robotically-processed photometry obtained from all images taken with AAVSOnet telescopes. The major component of this database are observations from the Bright Star Monitor network, as these telescopes have taken the majority of images. There are smaller datasets from telescopes that were only operational during the early days of AAVSOnet, covering fewer targets but going much deeper and often with high cadence (time series). For all current telescopes, the intent is to provide public access to older dat
February 7, 2011: The star SDSS J133941.11+484727.5 has been reported in outburst by Jeremy Shears (Bunbury, UK). Shears reports this star at magnitude 10.4 on 2011 February 7.919 (JD 2455600.419). This is approximately 7 magnitudes above quiescence, which suggests a superoutburst of an SU UMa star or a WZ Sge-like outburst. Gary Poyner (Birmingham, UK) confirms this outburst, estimating the star at 10.5 on February 7.959 (2455600.459).
January 3, 2011: The campaign to monitor activity of the peculiar cataclysmic variable FS Aurigae, as announced in AAVSO Alert Notice 428 (see also AAVSO Special Notice #226), continues. Principal Investigator Dr. Vitaly Neustroev reports that the campaign is going well, and that he is very appreciative of your observing efforts and contributions.
December 1, 2010: A bright transient in Pisces was discovered by K. Itagaki at an unfiltered magnitude of 12.3 on 2010 November 30.50663 UT (JD 2455531.00663; reported by H. Yamaoka in vsnet-outburst 11854). The object was confirmed at V=12.1 by A. Oksanen (Muurame, Finland) shortly afterward (vsnet-outburst 11855), and I. Miller (Swansea, Wales, UK) reported the presence of superhumps with period 0.0571 day (reported by T. Kato, vsnet-outburst 11859). As noted by Yamaoka and by R.
