Parkes observations for project P1339 semester 2024OCTS_04

Full description

After applying an unsupervised machine learning pipeline to dataset, we found a series of "unknown-unknown" source in the sky. In the position right ascension 20:47:34.4 and declination -16:42:03, we found a broadband signal that last a few seconds. However, through the 60 second observation it repeats. The observations corresponded to testing the multibeam system by pointing each of the beams in turn at a pulsar. Our signal was detected in eight different beams in sequence (not the pulsar beam), with the same position at right ascension 20:47:34.4 and declination -16:42:03. Within a 0.23 deg radius to the anomalous event, GAIA has identified a total of four sources located within 100 pc. One of them is Gaia DR3 6886074198993703168, a white dwarf candidate. We speculate that the observed anomalous event could potentially be a stellar flare originating from one of the stars within the covered region. If this anomalous event comes from a white dwarf, then it could be the second confirmed radio active pulsar emitting white dwarf after AR Sco.
