1 G. Murawski, 2020 (online data) The target shows high amplitude variations in long time scale. Magnitude range in 2018: 19.0 - 20.4 r. Only one detection in 2019 above noise by ZTF (r = 21.8) and only occasional positive detections by Pan-STARRS1 suggest the rise in 2018 was an outburst. BP-G= 0.0; g-r= 0.00.
