Thanks for your response, Peter. I did not see the recent VSNET announcement regarding these two objects and your observations. I have, however, seen the VSNET...
Is there perhaps a way to get the Quick Look Files to list only the visual data? The situation with HS 2331+3905, with CCD observers reporting thousands upon...
On the main Quick Look interface (http://www.aavso.org/data/ql/) there is a box you can check that says "Filter out CCD observations." -- Aaron Price Graduate...

From my observations of last night, it would appear that during the past 24 hours V5558 Sgr has entered into yet another secondary maximum, rising from the mid...
Hi all, It's about 1.5 months since KT Per has shown an regular outburst. Has the interval lenghtend? Is KT Per experiencing a low state like RX And did in...
Although KT Per (= GR 91) is classified as a Z Cam type system, this classification was apparently solely based on the fairly short outburst cycle (see the...
... Has ... RX And ... As other here have suggested, something rather odd appears to be going on with KT Per of late. Although I did not examine the longterm ...
The CV SDSS J090103+480911 was observed in outburst on 2007_10_06.2863 UT at mag ~ 16.1 (unfiltered, V zero point). Several hours of time series observations...
It is interesting to see KT Per's long delayed outburst occur only two days following the posts here concerning its inactivity. Taking LAI's reported...

I added this rather odd object to my observing program last night but have been unable to find much regarding it on-line. Neither do the AAVSO files recognize...
John, I managed to get some info on AAVSO VSX using NSV 24607 (note the space after NSV). IBVS 5608 will also give you more information on this unusual...

Hi all, On the internet I've found a note by Bruce Sumner about V381 Lac. This variable is discovered by L. Dahlmark, a Swedish retiree. In 1968 and 1993 he...

There certainly is a variable closeby, but it's not a dwarf nova (and not a Mira either): <http://skydot.lanl.gov/nsvs/star.php?num=6089551&mask=15636>. ...
... There's a variable star NSVS 6089551 at this position: 22:15:58.56 +42:22:45.12 (error 1.63" in RA, 3.42" in Dec) The lightcurve is showing rather...

RX J1831.7+6511 is a dwarf nova that has been found recently by Pretorius et al. (http://arxiv.org/abs/0709.1887). They observed it on three consecutive...
