Martin, Could you give us more information on Z Aps please? Is this a rare outburst, as you have announced it on baavss alert? AAVSO haven't anything in QL. ...
... This is essentially the normal range of Z Aps (our light curve generator shows 11-12 visual). In addition, Marino and Walker, 1991IBVS.3664....1M indicate...
... Z Aps is not a cataclysmic variable as stated in the GCVS but a CWA/RVA variable with a range V= 10.8-11.8 and a period of 19.02/38.04 days depending on...
... I should also mention that the light curve generator needs to have the date range set to about 4000 days. You will notice the big gap for the last 2000...
Thanks Sebastian & Arne. Would observers please check before posting outburst alerts on some of these more obscure objects (obscure for us Northerners of ...
Thanks to AAVSO observer Alexandre Amorim for observing V1017 Sgr recently. It seems visually it is still brighter than quiescence at magnitude 11.7. Here is...
Members will probably be aware that registration for this meeting is now open - see www.regonline.com/aavso-baa I hope that many of you will be able to attend...
Dear All Gary has suggested that I post some details of a variable object that I have discovered during my SNe patrols. It is close to UGC 3732. Its position...
Gary is correct of course - my only excuse was that I had done a search for UGZ stars in VSX. Z Aps come up so when its magnitude was at or near the max quoted...

Outbursts in this proposed Intermediate Polar are usually very short. From memory, I think all past observed outbursts have ended after just two days or so...
I have started an unfiltered time-series on this star. At 01:45UT 11 Feb the star was at approx unfiltered mag 14.0. I will continue my time-series as long...
... These are unfiltered images, right? USNO-B lists this star at B1 20.75 B2 19.40 R1 18.88 R2 19.02 I 16.95 NOMAD gives V=17.97 from the YB6 catalog, and J...
I have started an unfiltered time-series on this star. At 01:35UT 12 Feb the star was at approx unfiltered mag 15.3. Clouds may terminate this time series in...
We confirmed the outburst of HV Vir (WZ Sge star) using the 1.5m KANATA-telescope. Our start observation just after the report [vsnet-alert 9912] by R. ...

This extremely rare outburst is only the fifth confirmed in this UGWZ star - 1929, 1970, 1992 & 2002. The 1992 & 2002 outbursts were detected by Patrick...

We performed time series observations of HV Vir. We noticed that humps seemed to be in our preliminary light curve (may be early superhump). Its amplitude is...
