The planned outburst of the recurrent nova T CrB has still not occurred. There are, however, plenty of interesting phenomena in the sky and likewise many activities by the members of the common Section of Variable Stars and Exoplanets of the Slovak Astronomical Society at the Slovak Academy of Sciences and the Slovak Astronomical Union …

Variable stars in 2024
Like nearly all stellar astronomers, the members of the Section of Variable Stars and Exoplanets of the Slovak Astronomical Society at the Slovak Academy of Sciences and the Slovak Union of Astronomers (hereafter “the Section”) eagerly awaited the eruption of the recurrent nova T CrB predicted for 2024. They did not merely wait passively but …
Variable stars in 2023
This is another in a series of reports that I began preparing on my own initiative in 2021. It has become a good custom to divide it into two parts: one celestial, about the interesting behavior of stars, and one earthly, about the activities of the members of the Section of Variable Stars and Exoplanets …
Variable stars in 2022
Thanks to a fortunate time-space configuration, signals about several interesting phenomena in our Galaxy reached Earth during 2022. In this post I will summarize the basic information about some of them. First of all, novae that exploded in the period of 2020, 2021 were still active. Of them, I will mention two completely opposite objects. …

Unprecedented rate of novae for northern observers. Final count is six in one year included the recurrent symbiotic nova RS Oph as the most important event. The photometric an spectroscopic coverage made at the Kolonica observatory is also unprecedented. The first results were presented at the Bezovec conference and will be published in the proceedings. …
MU Cam – orbital sidebands
Long term monitoring of intermediate polars is performed as a part of the InterLongitude Astronomy campaign. High quality and long time series observations allow us to investigate fine effects on complex light curves. Inthe case of MU Cam we have investigated the periodic modulation of the spin phases with the orbital phase. This dependency was …
