Abstract:
We report two possible TDEs identified by our photometric classifier POTICA (Photometric Optical TDE Identification and Classification Annotator). Both objects are distinctly blue and still on the rise, currently at magnitudes 18.7 and 19.2. We encourage classification and follow-up of these objects.

POTICA (Photometric Optical TDE Identification and Classification Annotator, pronounced potitsa, a typical Slovenian dessert) is a fast TDE candidate classifier that processes ZTF nuclear transients. Using a Gaussian rise and an exponential decay, we fit and extract features from the ZTF lightcurve data and perform a binary classification TDE/SNIa, with an additional category for inconclusive events. The purpose of POTICA is to photometrically select potential TDE candidates as early as possible to follow up with spectroscopic observations. POTICA is currently available as a public annotator on the Lasair broker.
