Abstract:
We report the spectroscopic classification of 5 optical transients discovered/co-discovered by the Large Array Survey Telescope (LAST).

We report the classification of 5 objects discovered/co-discovered by the Large Array Survey Telescope (LAST, Ofek et al. 2023; Ben-Ami et al. 2023). 

All observations were performed with the DeVeny optical spectrograph on the 4.3-meter Lowell Discovery Telescope (LDT) , using the DV2 grating, on the night of 2025 March 19th (MST). Classifications were done using Next Generation SuperFit (NGSF; Astronote 2022-191) via the WISeREP (Yaron et al. 2012) web interface.

LAST is a survey telescope array operated by the Weizmann Astrophysical Observatory (https://www.weizmann.ac.il/wao/).

Lowell is a private, non-profit institution dedicated to astrophysical research and public appreciation of astronomy and operates the LDT in partnership with Boston University, the University of Maryland, the University of Toledo, Northern Arizona University and Yale University. The upgrade of the DeVeny optical spectrograph has been funded by a generous grant from John and Ginger Giovale and by a grant from the Mt. Cuba Astronomical Foundation.

The classified objects are listed in the Related Objects table below.
