AT 2018bej/ASAS-SN 18jj was discovered on 2018 May 3 23:02 UT by the ASAS-SN survey, at a brightness g' = 12.1 mag. Its J2000 coordinates are RA = 06:26:20.76, Dec = -69:45:46.30, implying that it is likely in the LMC.
We obtained spectroscopic observations of ASAS-SN 18jj with the Goodman spectrograph on the 4-m SOAR telescope on 2018 May 5.0 UT, with a low-resolution spectrum (R~1200) covering 3850--7850 A. The spectrum indicates that ASAS-SN 18jj is a young classical nova, with strong hydrogen Balmer emission lines and additional strong lines of [O I] and Fe II. The Balmer lines show P Cygni profiles; the FWHM of the H alpha emission component is 2210 km/s, and the absorption trough extends to -2960 km/s.
