GCN 20784), placed at the edge of the\nGalactic Bubble N82, seen in IR by Spitzer (Churchwell et al., 2006, ApJ,\n649, 759). This source was within the error box of the transient candidate\nfound in the AGILE-GRID data, AGL J1914+1043 (Tavani et al. GCN 20754).\n\nThe observations were performed using the 32-m Medicina radio telescope on\n2017-03-06 UT. We detected a bright radio source at the center of the\nobserved field of 1 x 1 deg. The source appears slightly larger than the\n7.4 arcmin beam of the receiver. The flux density at 5 GHz was 3.3 +/- \n0.5 Jy\n(MJD 57818.4375). The source emission, peaking at RA=19:10:30, \nDEC=+07:52:00,\nis compatible with the coordinates of the Galactic Bubble N82, including \nthe\nNIR Kanata source.\n\nWithin the half-power-beam-width from the source centroid, 7 radio sources\nare present, mostly unidentified. We report below a list of the sources,\ntheir coordinates, flux density, radius and possible association (source\nSIMBAD):\n\nNAME                R.A.
