Fwd. from ATEL ... -- The Astronomer's Telegram http://www.astronomerstelegram.org ============================================================================...
I took a few frames of this field last night. At JD 2453891.71 the object was approximately mag. 19 (unfiltered CCD). It's too faint for me to do any work on...
Hi, I'm hoping to engage some of you to help me solve a problem. Last autumn I detected variability in the star GSC 3132 1448 which is marked as comparison...
It is with some little annoyance that I note that whilst examining a small subset of light curves of objects mentioned in the NSVS red variables' paper...
Dear All, ... this is a CV that we had identified a couple of years ago in the Hamburg Quasar Survey, but did not publish it yet as we did not manage to pull ...

Boris, Do you have a quiescent V magnitude - and more importantly, have you seen much activity? Cheers, Gary ... Gary Poyner garypoyner@... ...
Hi Gary, ... We got spectroscopy on two occasions (March and April 2004) and I-band light curves in May 2005. It is from those data that we suggest an orbital ...

Addendum: HS1055+0939 is indeed in the SDSS area, but did not get a SDSS spectrum, probably because it is too red to be of interest to the Sloan people. Boris...
Catching up on some reading, I see in the May 25, 2006 edition of Eyepiece Views http://aavso.org/publications/eyepieceviews/0506.shtml is a review of the...
If this is true, please get time series on it as long as possible. Unfiltered is fine. Precision and length of observing run is more important than time...

Folks, Just took a 20 sec CCD exposure (22 June at 21h15m UT) in twilight at CBA Belgium Observatory of the BZ UMa region. The object indeed is in outburst ! A...
Over the last two nights I have made positive observations of three lesser studied CVs in Cyg and Lyr. Not all that earth shattering of news, granted, but one...
Hi Mike, I made 80 minutes run on V1006 Cyg last night with 30 cm Casegrain telescope and Meade DSI Pro CCD. There is no periodic signal in the data. Clear...
Thanks Pavol. It looks like we can rule out the 'V1106 Cyg= possible UGSU' scenario. This outburst may be more indicative of its normal behavior, in spite of ...
Hello, The Austrian astronomer Klaus Bernard discovered the cataclysmic nature of the star RXSJ053234. Since its discovery, there were two outburst: - a...
The current outburst of 1RXS J053234.9+624755 should be a supermaximum. Unfortunately it is not the best season now to observe this DN. Regards, Patrick ... ...

Hi Erwin, A good article about the previous superoutburst is at the following link ; http://arxiv.org/ftp/astro-ph/papers/0605/0605394.pdf Regards, Eddy ... ...
There seems to be some question as to whether QW Ser is actually in outburst or not. The visual observer who reported the outburst is usually quite dependable ...
A paper entitled "CG Draconis, a particularly active dwarf nova" by J. Shears, R. Pickard & G. Poyner, and accepted for publication by the JBAA is now...
The 78th Name-List of Variable Stars with for identifications of 1706 'new' variables was published on 8 August 2006: http://www.konkoly.hu/cgi-bin/IBVS?5721 ...
... Dear all, I must say that the reason of changing T Leo with QZ Vir is slight unclear for me. I understand such a renename for newly named stars. But T Leo...
From visual examinations of several images taken around 02:15UT Aug. 21, it appears V1108 Her (Var Her 04) is active at approximately 16.3V. All my previous...
You are quite sure of the V1108 Her observation? I must remind people that there is a one arcsec companion at about this magnitude in V (much brighter, of...
Yes, I am aware there is a close companion. I'm working from memory here, but I recall seeing two stars, the variable being the western of the pair. The seeing...
Again, VarHer04 is a *close* double. The spacing is one arcsec, unresolvable with most amateur setups. The star Mike mentioned as a "companion" is 4.5arcsec...
