Fresh data on the transient GOTO065054.49+593624 2024, classified as dwarf nova subtype WZ Sagittae (WZ Sge). A particular type of cataclysmic star with an interesting behavior. Apparently, we have witnessed a superoutburst and a superhump, which ended around 12-14 days after the maximum (as described in the literature).

Two days ago (Oct 18, 2024) we recorded a sharp dip in the brightness, and today a sharp return to the previous state. 

At a detailed level, the light curve's shape has also changed, with small alternating humps appearing, probably with a duration close to the orbital period. A check with the Lomb-Scargle algorithm in the Peranso program shows approximately 1.5 h.

Clear nights are coming, to be continued...

BL Lacertae or BL Lac is an active galactic nucleus (AGN). Unlike other types of active galactic nuclei, BL Lac is characterized by rapid and large amplitude flux variability and significant optical polarization. Because of these properties, BL Lac was originally considered a variable star. The observed nuclear phenomenology of BL Lac is interpreted as being due to relativistic jet effects close to the observer's line of sight. Regarding the AGN classification, BL Lac is a subtype of blazars. A new outburst of BL Lac was reported with a peak brightness of 12.6 magnitude in the V-band. During the phenomenon, several observations including time series and single estimates in the three bands B, V, and R were carried out by the Observatory "Meshtitsa". The observational data have been published in the AAVSO international database. 

Nova V615 Vul was discovered on 2024 July 29.832 UT. Meshtitsa Observatory has been actively involved in the campaign to track the brightness change in the three bands B, V, and R. The observational data have been published in the AAVSO international database.

The supernova in the galaxy NGC 4216 was detected by Japanese amateur astronomer Koichi Itagaki on January 4, 2024. The supernova was classified as a Type Ia - a nuclear explosion of a carbon-oxygen white dwarf reaching the Chandrasekhar limit. In the following months, the supernova was also imaged and observed repeatedly by the Meshtitsa Observatory. The observational data have been published in the AAVSO international database.
