We report the classification of AT 2017ego from a spectroscopic observation made on 2017 May 29 UT
with the DEep Imaging Multi-Object Spectrograph (DEIMOS) on the Keck II 10-m telescope. We also
confirm the classification of SN 2017eir (ATel #10454). The classifications were performed with SNID
(Blondin & Tonry, 2007, ApJ, 666, 1024).
IAU Name | RA (J2000) | Dec (J2000) | z | Type | Phase | Notes
AT2017ego | 23:35:23.54 | +03:05:07.48 | 0.063 | Ia | -2d | (1)
SN2017eir | 23:51:49.57 | -04:45:45.14 | 0.089 | Ia | 0d | (2)
(1) The best fit to SN 1996X.
(2) Already classified in TNS (ATel #10454). The phase and the redshift are consistent with those
in the previous classification.
