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...

Hi Mike ... You can probaly get a more reliable impression using image subtraction. Image subtraction requires a comparison image of good quality and the same...
... I've placed on http://www.aavso.org/tmp2/v1108herv.jpg a one arcmin finding chart for V1108 Her to show you the confusion problems with this field. In...
Dear All, please follow this system closely ... it is only the third or fourth observed outburst, and so far no superhumps have been detected - even though the...

Dear All, apparently I was still asleep this morning: we did observe one superoutburst of HS0417+7445 ourselves! But we only got a bit of data, and were unable...
The last time V1363 Cyg was this bright was Jly 10 2006, when it was recorded at 15.77C. It peaked at 15.6C about two weeks before, so didn't get very bright...
You mean 1994! There was one in both 1993 & 1994. Good luck for tonight. My fingers are crossed for clear skies here in good old Brum! Gary ... Gary Poyner ...
Dear All, it has been a while since I asked for your help in monitoring new CVs which were identified in the Hamburg Quasar Survey (see message 388). I have...

Dear Boris, Sadly, the only data I have so far is for HS1552+2730 = RX J1554.2+2721 = AP CrB as it is also on your "polar" programme as published in the last...

It I might suggest if observers are doing V-band (or any other filter) photometry, go ahead and report it first to the AAVSO. If Boris wants specific star...
Hi Arne, OK - your suggestions sounds good, the data has definitely go into the AAVSO archive, and if it keeps things easier for the observers, I will get the...

I carried out unfiltered photometry on this object for 90 mins from Oct 24.177 this morning, i.e. until dawn. During this time the object declined from 16.2C...
