EP-WXT trigger 01709018832: Lick/Kast spectroscopy with the 3 m Shane telescope
Abstract
We observed the star Gaia DR3 2445442335531658752, the optical counterpart of an EP flare event (trigger ID 01709018832; Jiang et al., GCN 37090; Zheng et al., GCN 37095; Han et al., GCN 37109), with the Kast spectrograph on the 3 m Shane telescope at Lick Observatory. Observations were performed on Aug. 14 UTC, about 7.2 days after the trigger, covering the 3500-10,000 Ang wavelength range, with an exposure time of 900 s. The spectrum shows a red continuum flux with superposed strong hydrogen Balmer emission lines as well as Ca II H&K and TiO emission lines, consistent with a typical dMe star spectrum, confirming this to be the flare star related to the EP flare event.
