So, basically there's been no confirmation, no news of the original images being provided, no explanation of why you should be looking at something low on the...
My observations show that ST LMi has moved into a low state sometime between Jun 9 and Dec 2, 2007. This change is verified in a (1 Porb) time series carried...
Today on CVnet http://cvnet.aavso.org we are featuring an interview with Dr. Boris Gaensicke. He talks with Gary Poyner about cataclysmic variables, population...
CBA Atacama (0.5M, STL-11000, unfiltered, 20 second exposures) astrometrically and photometrically confirms XZ Eri in outburst at unfiltered magnitude of...
Eight hours of time-series data by CBA Atacama shows superhups (rapidly evolving), with an amplitude of 0.4mag, at an average unfiltered magnitude of 14.7. ...
Another UG star which is somewhat overdue for an outburst is DX And. With a mean catalogued outburst period of 214d (too short in my opinion), the last...

Boris, Even though I'm not directly affected (I'm just a retired Aussie) I find these drastic cuts to the UK's scientific funding in these areas distressing...
A.J. Drake et al have reported in A.Tel #1337 on the detection of a bright optical transient in one of the spiral arms of the Antennae Galaxies (NGC 4038/VV...
Hello Gary, unfortunately the minimum of S5 0716+71 we observed recently is far away from a historical low state. A long-term optical lightcurve was published...
I observed this star for over 6 hours last night during which it showed much scatter around a mean 15.5 CCDV. The scatter was generally between 15.2 and 15.8....
Chris LLoyd and I have been looking at the outburst behaviour of the UGSU star V452 Cas over the past three observing seasons. At one time V452 Cas was thought...
