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).

(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.
