[vsnet-alert 10798] Re: re ST CHA in outburst?

[bydra at Safe-mail.net]

Okay, I'm getting the gist of this now.

Years of goodly visual data from seasoned Southern Hemisphere devotee Rod Stubbings, plus some stuff too from another such seasoned Australian visual CV observer Andrew Pearce if you dig out the AAVSO archives (hmmm, I haven't heard ought of him in ages) gives a lightcurve that ain't UGZ like or eclipsey like, and Rod S's prolific data at least shows no periodicity signal (I don't want to hear that it's visual data, folk'd be amazed what info quality visual data can carry if they just look)...

...meanwhile, back at the ranch, Southern Hemisphere amateur CCD pioneer user and long experienced variable star CCD measurer, also with a penchant for specialising in CVs, Berto Monard, did a two hour time series of the thing a couple of years ago and found it more constant than a very flatlined thing...

...whilst the literature period is shown to be the data channeling, either via interference, confusion or mistaken identity or combinations or however, an adjacent field (or possily cpm) contact binary...

...leads to let's look at it it'd be great if it was an eclipser?  Commit them resources, drop everything else.  We've got a interday and intraday erratic here, let's try and see'f we can find some not even remotely guaranteed eclipse out of that mess?


Incidentally, anyone know why the United Kingdom built the Liverpool Telescope or whatever it's called, and/or what it's used for?  It was supposed to be for stuff like transients and CVs etc, so they said on ol' Sir Patrick's telly proggie years ago, I remember watching it.  There's barely been a paper or two out of the thing that I've ever noticed.  In fact, I wasn't sure it was finished until I heard it might be scrapped during the last budget cuts, apparently it having been used for years.  Maybe put in a proposal for that to get the time series of this object for you, spectroscopic time series, or is it too far South for that 'scope?  Or is it alright for amateurs to wild goose chase, but not professionals?  After all, they're only amateurs, they should be glad of scientists showing interest in them.

It'd be great if it was an eclipser...

a lot of stuff'd be great if it turned out to be all sorts of stuff, given the resources to monitor it all.
