Napoleao on behalf of the Brazilian Transient Search - BraTS - at SONEAR Observatory, Oliveira, Brazil in three frames with 10 seconds exposure using an astrograph 280mm f/2.2 + CCD unfiltered, with magnitude 15.2 under limiting mag = 17.2. Nothing is visible at this location on the previous frame (limiting mag = 17.1) taken on 2020 Mar 19.3296 UT.

Libert ("Berto") Monard (Kleinkaroo Observatory, Calitzdorp, South Africa) reports: "Astrometry vs UCAC2 frame on images taken on 30 March 2020 at CBA KKO give the position (2000): 17 40 37.23 -33 14 32.8, with estimated uncertainties (at 1 standard deviation level) of 0.02 in RA, 0.1 in Decl.; Gaia DR2 4054091412492716288 is proposed as the possible counterpart. Timeseries observations on 30–31 March at CBA Kleinkaroo show no clear periodic modulation." —— Patrick Schmeer (Saarbrücken-Bischmisheim, Germany)
