Graham report/s a classification of object: AT 2021dhg
Type: NovaRedshift: 0.001361
Remarks: We note that taking into account expansion velocities and the slow rise of the light curve (combined with a luminous absolute magnitude), we cannot rule out a different classification for this object (for instance, a “gap transient” (Pastorello & Fraser, 2019).
The following Classification spectrum was provided:
