We report on an optical and radio brightening of the distant (z=0.914) flat spectrum radio quasar (FSRQ) PKS 0420-014 (RA=04:23:15.8, DEC=-01:20:33.1, 2000.0) observed by the WEBT-GASP collaboration. In the optical band, it was observed at R=14.43 on January 21 (St. Petersburg University), which is comparable to the level of the optical outburst from 1995 (Raiteri et al. 1998, A&AS, 127, 445). Previous data indicate that the source brightness was R=15.44 (Sabadell Observatory), 16.25 and 17.18 (Crimean Observatory) 32, 42, and 52 days earlier, respectively.
