According to observations in the AAVSO International Database, KX Aql went into outburst from <14.0 (BRJ, J. Bortle) on JD 2444552 (8 November 1980) to 12.7...
Thanks Elizabeth for the data on KX Aql. It must have been some sort of superoutburst. Pity the recent outburst was very short. It still is on my 'wanted...
All, As most of you know, the recently discovered "exoplanet" XO-3b is currently at the center of an interesting debate over the classification of this object...
I collected nearly 4 h of photometry on this star last night, from Jun 8.913 to 9.075 (effectively dusk to dawn on these short northern nights, with a couple...
I followed Jeremy's lead and uploaded the light curve of SDSS J122740+513925 in the files section. The light curve spans 4.5 hours on 2007_06_07.0796 to...
Obtained ~3.5 hours of data last night from June 9.91 to 10.05 (increasing haze towards dawn resulted in the run being terminated). The star was slightly...

Many thanks, Arne, for your hard work on this. I assume the 2 stars you recommend are GSC3458-372 and - 2088 respectively? Just for my learning, what leads you...
... My basic selection guidelines for choosing comparison stars: 1) similar in color to the variable, if possible, but understanding that red stars are...
Arne, would you explain gradient effects. At least the ones that you refer to in this post. Leonard Koscianski ... stars you recommend are GSC3458-372 and -...
A casual inspection of the various light curves obtained so far, suggests that there is considerable superficial variation between runs in terms of the overall...
... If you have a gradient in your flatfield that is caused either by nonuniformity in the illumination or by scattered light in your telescope system, then an...
Hi Here the same "technique" as with visual observers and vignetting eyepieces might help to reduce this effect: Place the var and the (main) comp at the same...
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...
Hi Berto, I recall Frank Bateson had an interest in EK TrA as this star appeared to have an unusual outburst pattern where it showed intervals of increased ...

Hello all, I'm just posting a quick questions. Can anyone of you tell me where I can post my images of recent novae on the web, where all of the variable star...
... Certainly supernovae have their sites, such as http://www.supernovae.net/snimages/ but I don't know of an equivalent page, with images, available for...
Arne, that would be great! It would be good to have a pictorial archive of novae and other variables as well as relying on the old text based visual estimates...
... me where I can post my images of recent novae on the web, where all of the variable star community can access?? ... used by everybody worldwide? ... Keith,...
... Hi John, Images can be used to confirm a nova, for researchers to analyze (such as to get improved astrometry), and for identification (since novae always...
... Keith, If you really wanted others to see your Nova pics, then we do have web space available on CVnet discussion. Just go to the files section, and...
If you want you can post it to me ,and I pub. it on site: http://sabbe.fragzone.se/KPO/VARIMA.htm and of cause with your name. Regards hans-goran lindberg ... ...
Hi John, just like Arne states, it's been done with Supernovae in many external galaxies for years. I'm sure imaging a nova field could yield possibily...
... many external galaxies for years. I'm sure imaging a nova field could yield possibily additional information regarding it's classification, confirmation,...
... I must agree and yet disagree with John. Certainly, "hobbiest" images have little scientific value, just as similar images for supernovae are not often...
