Knezevic on behalf of ePESSTOePESSTOOtherePESSTOePESSTO observed the X-ray binary in outburst (and black hole candidate) MAXI J1820+070 (aka ASASSN-18ey, aka Gaia18as; ATel#11399, ATel#11400). Our spectrum, with a very blue continuum, shows H, N III 464.1, He II 468.6 and (weaker) He I lines in pure emission, and agrees with earlier descriptions in ATel #11424 and ATel #11425.
