Confirm presence of new object. Astrometry with UCAC2 data (15 reference stars) gives the following: (11-inch SCT, f.l.=2850mm) UT date of obs, YYYY MM DD:...

SDSS163605.01+465204.5 Feb 7.247 15.4C This is the first time I have observed this star so I am not sure what it's normal mag is, although I note in Mike...
Hello Jeremy, Looking at DSS images there are indeed two stars of similar brightness with a separation about 3". The CV is the western one. In infrared it is...
... Under poor conditions I measured it at v = 9.47 +/- 0.04 at Feb. 7 11:20 UT (JD 54138.97), using ASAS V = 9.54 for TYC 7364-1358-1. Using Tycho B-V for...
Further to Arne's note (below), I have drawn up a chart and sequence that extends the current BAAVSS sequence from 13.1V to 16.3V. My comparisons are overlaid ...

We are going into our third year of full contact cataclysmic variable activity, discussion, sharing and reporting on CVnet. I'd like to take a moment to thank...
Thanks Boris. So it could be UGSU then? You will have seen that I detected a brightness variation - pity I wasn't able to do a longer run. Interested observers...
SS Aur certainly is in outburst, but I found it very difficult to visually evaluate using the 110 and 109 comp stars on the 3-08-25 AAVSO chart. The star...
Neither star is red, in fact they are both fairly blue, so color shouldn't be a factor. 109 is definitely brighter, but not by very much. I'd probably use the...

I'm looking for images of DV Dra in outburst (last one was November 2005) to settle an identity question that keeps popping up on the AAVSO charts. FITS, GIF,...
Hi Mike, I have 53 images taken Nov. 25, 2005. Since they are all 518 Kb, there is no way my "slowdem' will get them all out to you. I can compress the fits...
Hi All, The Dutch observer Reinder Bouma produced a chart for V2467 Cygni that goes down to the 15th magnitude. That is much fainter than the sequence now...
Hi All, Arne Henden has updated his sequence of V2467 Cygni. Reinder Bouma updated his chart aacordingly. It is available on http://www.shopplaza.nl/astro/...
Thank you everyone who sent images or volunteered images. We have it all sorted out now. The AAVSO chart and sequence were pointing to the wrong star. The real...
