1 Schmeer, Patrick A 600 s spectrum obtained on on 2019 Aug. 8.19 UT shows broad (FWHM ~2500 km/s) Balmer absorption, with narrow (~400 km/s) emission superimposed on H-alpha. He I absorption lines at 447.1 and 587.6 nm are also observed. The spectrum is consistent with a dwarf nova in outburst (ATel #13034).
