    The paper “The Zwicky Transient Facility Census of the Local Universe I: Systematic search for Calcium rich gap transients reveal three related spectroscopic sub-classes”

    Kishalay De et al

    has been accepted for publication. It includes a spectrum of SN 2018gwo taken with the modified ALPY200.

    It was discovered by amateur Patrick Wiggins and I initially classified it spectroscopically as a type 1c supernova.  It turned out to be a rather rare Calcium rich gap transient supernova, based on a spectrum taken in the nebula phase 5 months later using the Keck 1 telescope. (One of only 8 out of 754 supernovae found during the survey period) so I am included as a co-author. ZTF use a spectrograph with a similar low resolution to the ALPY 200 (R~150) to classify transients they find but the system was down for maintenance at the time. But for the amateur discovery and initial classification of SN 2018gwo, it might have been missed.

    Cheers
