V & B Measurements for T Corona Borealis (T CrB) previous to its predicted (expected) eruption

Here we present multi-band photometric follow up observations of 9 optical transients using 1.82-m Plaskett Telescope + CCD at Dominion Astrophysical Observatory of the National Research Council of C…

Here we present Sloan g' band photometric follow up observations of 8 optical transients using 1.82-m Plaskett Telescope + CCD at Dominion Astrophysical Observatory of the National Research Council o…

Here we present photometric follow up observations of 3 optical transients discovered by GOTO (M. Pursiaine., et al.), GEOTS (B. Kumar) and MASTER (T. Pogrosheva., et al.) using 0.33-m Telescope + K…

Here we present multi-band photometric follow up observations of 5 optical transients using 1.82-m Plaskett Telescope (E2V, 4K x 2K CCD) at Dominion Astrophysical Observatory of the National Research…

We report the spectroscopic classification of 2 Type Ia SNe, a Cataclysmic Variable and a Seyfert 1 galaxy.

A Keck DEIMOS spectrum was taken on 2022-06-08. A clear H-alpha emission at z=0 is identified, which suggests AT2022lnd is a galactic CV.

We report the classification of AT2022lnd as a rapidly fading galactic CV. Spectroscopic observations were performed on MJD 59735.95 (2022-06-05.95) with ALFOSC on the Nordic Optical telescope (NOT) …

We report the spectroscopic classification of AT2021tyc as an outburst of a Cataclysmic Variable.

We report the spectroscopic classification of AT2021pin as an outburst of a Cataclysmic Variable

We draw attention to the rapidly fading lightcurve of AT2021buk from the combined ZTF and ATLAS survey data. The nature of AT2021buk is consistent with that of foreground CV, however, it is possible …
