Can anyone point me to references discussing the evolution of Hydrogen lines in dwarf novae? I am trying to understand the variability in the strength of...

Hi Aaron, ... I'm not entirely certain what your question is: "well behaved" dwarf novae have emission line spectra in quiescence, as some part of the disc is...

Thanks for the reply. We have many spectra of Var Her 04 in quiescence over many months. Most of the spectra are similar, with prominent Balmer lines. But in...

Hi Aron, OK, I see what you mean - we noticed something similar in BC UMa, Gaensicke et al. 2005, ApJ 629, 451, Fig. 1. We believe that this change is due to...

Yes, the long holiday weekend and four clear all nighters has made me a little fuzzy. I am referring to V1316 Cyg, not V1363. Both are interesting targets. ...
I agree with David. I've been carrying out a time series run on this star for almost the last 3 hours during which time the star has shown a slight fade from...
Hello Michael Thanks for the info. Please, report your measurement even if it has a larger error/ uncertainty than usual and continue to monitor it. ... VAR...
Dear all, Cheking my observations of V1663 AQL, I find a possible low amplitude variable star near 122 star. I find nothing on SIMBIAD about the variability of...
Hello Hans-Göran There is a confirmation from Jörg Hanisch that its faint (see below). The FL of Jörg's and Michael's scope is 2.7 and 3 m. About 3x as long...
Sure i belief its faint , and i know that my resolution is bad, and i dont use binning, only stack 4-5 images. The image from 2005-09-05 UT 20:25 is not...
I guess we will have to say the results as to whether or not V1316 Cyg was in outburst are inconclusive. Keith Graham had it at SEP 06.2097 2453619.7097...
Dear colleagues, Following the recent announcement on CVnet of an outburst of the UGSU:-type dwarf nova FS And, I started an unfiltered CCD photometry session...

I found a few CCD comparison stars for TT Ari: This one is from ASAS-3: RA: 02:07:14.2 Dec: 15:19:48.3 V:11.829 Verr: 0.039 Arne's .dat file is faint....

Hi All, I took BVRI photometry of TT ARI last night at 06, 08, and 11GMT but I can't find photometry for the BRI magnitude of the comp stars. In particular...

... Looking at my exposure logs, I took both long and short exposures of this field, so should have brighter stars calibrated than V=14. However, these frames...
Ok, I've checked my original images. The short exposures were to not saturate on TT Ari itself; the field of view was too small to pick up any of the brighter...
I have been monitoring a few CV's that do not seem to get much attention. One of these is Lanning 386 (21:08:34.03 +39:05:35.3) which was very active last...
Maybe another e-mail is in order then - or simply send them AAVSO charts for the stars they seem to be mis-id'ing all the time. If they are serious about...
In spite of previous private emails pointing out the mis-identification of variables by CCD observers using automated software and NOT using AAVSO charts we...
Please do not post observations to CVnet discussion. Your reports are better served going to CVnet outburst. (And the AAVSO International Database of course!) ...
