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.
