The Fast and Dark Side of Transients experiment (FDST; ATel #12362) reports the spectroscopic observation of SN 2019crb and ZTF19aapaeye. Targets were supplied by the Zwicky Transient Facility (https://www.ztf.caltech.edu/; Kulkarni et al. 2018, ATel 11266) and processed through the Lasair broker (Smith, Williams, et al. 2019, RNAAS, 3, 26; https://lasair.roe.ac.uk/). Classifications were determined using SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).
The observations were performed on 2019-04-07 using SPRAT (Piascik et al 2014) on the Liverpool Telescope (Steele et al. 2004).
