Lee\n(KASI) on behalf of the KU collaboration\n\nWe obtained r, i, and z-band images of MASTER OTJ033744.97+723159.0 near\nNGC 1343 (Lipunov et al. GCN 21719, 21720), a candidate counterpart of\nG299232/PGW170826 (Siellez et al. GCN 21693). The data were taken with\nSQUEAN instrument on the McDonald Observatory���s 2.1m telescope at\n2017-08-27, 10:57 (UT). Before Galactic extinction correction, it has r =\n16.67 +- 0.03 and i = 16.71 +- 0.03 (AB mag), with r-i color of r ���i ~\n-0.04 mag. However, after Galactic extinction correction, we get r= 15.89\nand i = 16.13 and r-i = -0.24 mag, a rather blue color in comparison to\nG298048 shortly after its discovery (Nicholl et al. GCN 21541).",
