A report on VSnet by Kato-san states that Nakajima-san has detected superhumps in V1454 Cyg (including obs on Dec 1). This confirms a UGSU classification. ...
I have collected a small set of images taken by amateur astronomers which show the region of Var Cas 2006 well before it brightened, a few days before the...
Roger Pickard noticed a mistake in my analysis of the Spink image, and suggested a fix. I have applied his fix and determined a much improved magnitude for...
I have added more images to the collection of pre-maximum images of Var Cas 2006. There are now two additional measurements of the star before maximum light....
You can pester me all you want ;-) I regularly photograph the night sky and back up my shots on disk, so as to have a historical library, I've really only...
I've stacked 50x30sec unfiltered exposures of this field and measured using Astrometrica and USNO A2. I make the object 18.66 CCD HS0128+3547 20061213.818...
... "Engulfs its companion," eh? Certainly V838 Mon has gotten fainter, but swallowing its companion is pretty extreme wording. I think the more likely reason...

This enigmatic variable has been classified and re-classified several times in the last few years. I think it is generally agreed now that DW Cnc is an...
Dear All, DW Cnc is a very puzzling object... ... Looking at its (relatively sparse) long term light curve, V~14.5 is its typical brightness, but it has shown...

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...

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...
