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...

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...
