SN2024ggi, a II-type supernova, was first found on April 11, 2024 by ATLAS project team. It sits in a nearby galaxy NGC3621. Mikhail Pavlinsky ART-XC telescope onboard Spektr-RG observatory was the first to register its X-ray emission.

Supernova SN 2023ixf, which blasted on May 18 in the Pinwheel Galaxy M101, appeared to become more and more bright in X-rays even after its optical luminosity started to fade. The results of the observations were published in Astronomer's Telegram.

Supernova remnant RX J1713.7-3946 hides in Galactic plane.

At first AT2020mrf seemed to be an ordinary optical transient, but thanks to SRG/eROSITA discovery of a new X-ray source in the same place it became clear that the astrophysicists have encountered the most peculiar object.
