Tech Explorist: An international group of astronomers has recently spotted an unusual nuclear transient in the nucleus of a weakly active galaxy using the OGLE-IV Transient Detection System and received designation OGLE17aaj.
Astronomers spotted this peculiar nuclear transient event in the nucleus of the galaxy GALEXASC J015624.70-710415.8, some 680 light years away from the center of the host. OGLE17aaj was detected by the OGLE-IV Transient Detection System in January 2017 and follow-up observations of this transient were performed subsequently using various ground-based and space telescopes.
