The current R Dra maximum was, as noted earlier, comparatively bright. My brightest observation was at 6.2 on December 13. Here are the latest six maxima as reported by Swedish observers:
First in the series of posts on lightcurves is T Cep, which has become one of my favorite variables. It is circumpolar, which is always a nice thing – no season gaps in the light curve. Also, it clears the … Continue reading
We run a programme of studying 50 neglected miras in the Swedish variable star community. After having found out, by chance, that one of the stars was in the Kepler field, I decided to check out if more of our … Continue reading
Here is a status report (in Swedish) for the project on 50 neglected miras observed by SAAF/SVO observers. Update: Thomas Karlsson has made a page that gives an overview of the observations in SAAF V/SVO programme of neglected Miras.
I’ve been observing KK Aurigae for some six weeks or so. It is situated close to YY Aurigae, a star I am observing for a programme on neglected Miras together with some fellow Swedish amateurs, and sometimes it ends up … Continue reading
Looking up W Aurigae in the Simbad database, we find that it is a double star, Cou 1725. Paul Couteau discovered the double star nature of W Aur in 1979, when he measured the star on three nights. The stars … Continue reading
Lydia Ceraski discovered 219 variable stars (or 180 – the literature disagrees somewhat). Among them are important ones such as SU UMa, RV Tauri and T UMi. Despite that, not much is known about her. She graduated from the Petersburg … Continue reading
One of the great visual surveys of the northen sky was done at Bonn by Friedrich Wilhelm Argelander with the aid of his asistants Eduard Schönfeld and Adalbert Krüger. They observed the sky north of -2 degrees declination during the … Continue reading
