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...

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 John, AS325 = NSV24607 is a symbiotic star that I calibrated as part of a request from Sebastian Otero, and the subsequent Alert Notice 321, as AS325...
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...
... Well, I have checked nine Palomar plates available, and the amplitude of the red star is at least 4 magnitudes in IR and R bands! Using nearby USNO-A2.0...
... Thanks for finding this reference, Den. As I said, the red star is obviously variable from my photometry. My concern is fourfold: (1) the Dahlmark...
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...
Patrick, it's not ignored by this CCD observer, although I have not followed it for long. I have had it between 13.6 and 15.8 (C) in the last couple of months....

Hi all, I'm looking for a fainter sequence for V518 Persei. The AAVSO-chart only goes to 14.1. Is there someone who know of a fainter sequence? Eddy [Non-text...
... Ah, that brings back fond memories. I observerd GRO J0422+32 during 1993, with deep time series work during November of that year, along with V404 Cyg,...
