Andrew Howell, Curtis McCully, Jamison Burke, Craig PellegrinoNoneSN Ia0.075609Using Superfit (Howell et al. 2005, ApJ, 634, 1190) and SNID (Blondin & Tonry 2007, ApJ, 666, 1024), we find good fits to several normal Type Ia SNe around a week after maximum at the host redshift (0.075609; 20096dF...C...0000J, via NED).

Comments

ATLAS AT report/s 40396 for 2019kam were associated with object 2019lqn.
Object 2019kam was removed from the system.

(Although the ATLAS report (which created 2019kam) was the first one, since 2019lqn has already been classified as a SN, 2019kam was removed and merged in 2019lqn.)
