ASASSN-19lb: Detection of an Unusual Stellar Outburst in the TESS FOV
Abstract
During the ongoing All Sky Automated Survey for SuperNovae (ASAS-SN, Shappee et al. 2014, Kochanek et al. 2017), using data from the quadruple 14-cm "Cassius" and "Paczynski" (CTIO) telescopes, we identified an unusual stellar outburst towards the Galactic plane in the TESS FOV. The source ASASSN-19lb (position from Gaia DR2, RAJ2000=174.95582, DEJ2000=-70.67553, source_id=5233532175492716032, G 15.7, d 1.7 kpc, l=297.02598, b= -08.62943) was first observed by ASAS-SN on UT 2015-07-18.
