I have been looking at the outburst history of AW Sge and I think that there is some evidence for an outburst cycle of 284 days. Only five outbursts have been...
I will add this star to my list of stars I monitor using my remote scopes in New Mexico. What filter would you suggest - I assume unfiltered in view of its ...
Martin, Yes, unfiltered is fine. The star is about magnitude 19 at quiescence and should reach 15 or perhaps 14 in outburst. Normal outbursts last about 4 days...
I think many of you would be surprised at the number of variable stars about which very little indeed is known. I am not just talking about very faint...
The ROP star V337 Cyg has been reported to be in outburst by T. Gomez (see below). This would be the first recorded outburst since November 2006 (normal...
Hi Martin, This programme is still very much alive. Chris Jones undertook an extensive revue in 2005 and as it is a long term (a few years, at least) project...
Hi Martin, I don't know what anyone else is doing but I've worked up about half a dozen of these stars, mostly the Mira candidates. Chris ... Yahoo! Messenger...
I am very pleased to hear that this project is still on-going. Of course some of the entries are probably quite well covered by the Northen Sky Variability...
Hi Martin, Rest assured we take all available data into consideration. That said, thanks for the info which I will forward to Chris Jones just to make sure ....
R CrB has shown smooth cyclic variations between 5.9 and 6.1 during the period March to May 2007. This is typical behaviour for this star when at maximum ...
