We report the spectroscopic observation of ZTF20aabbimu flagged by a custom filter on the ANTARES alert-broker (https://antares.noao.edu/) to find explosive events from the public alert stream of the ZTF survey.
Name | RA (J2000) | Dec (J2000) | First detection: MJD, mag
ZTF20aabbimu | 03:18:00.47 | 73:39:50.15 | 58850.134838, R~13.5+/-0.01
On 2020 January 5 UT, we obtained an optical spectrum of this source with the Kast double spectrograph on the Shane 3 m telescope at Lick Observatory. It shows the higher-order Balmer lines in absorption and H-alpha with an emission core, thus indicating the source to be a dwarf nova.
