Bhalerao (IITB) report on behalf of the GROWTH collaboration:\n\nWe cross-matched the HAWC trigger position (HAWC Collaboration, GCN 26472) with the GLADE catalog (Dalya et al., 2018), to identify sources within 0.9 degrees (approximately 3-sigma) of the HAWC position RA, Dec = 323.53, 5.23. We further applied a distance constraint based on the 3D Bayestar localisation provided by the LVC (bayestar.fits.gz,1), using mean distance = 95.6 Mpc and distance sigma = 37.4 Mpc, appropriate for this direction. We find four objects in GLADE 1 (http://vizier.u-strasbg.fr/viz-bin/VizieR-3?-source=VII/275/glade1) that are consistent with the position and distance at 3-sigma:\n\nra         dec        sep   dist     sigma\n323.124298 5.346313    0.42 85.3405  1.43\n323.741486 5.792747   0.601 150.166  2.48\n323.621368 6.034144   0.809 85.5611  2.71\n323.298126 4.682521   0.594 173.891  2.88\n\n(sep = separation in degrees).\n\nIf we use the newer Glade 2.3 catalog (https://vizier.u-strasbg.fr/viz-bin/VizieR?-source=VII/281), we find only the first two objects as consistent within 3-sigma.\n\nFurther observations of these galaxies are under way.",
