The observations started 10:12 UT on 2019 April 25\n(about ~1.9 hours after the event) and the median 5 sigma upper limit for\nan isolated point source in our images was r > 20.8. No transients were\ndetected in any of the galaxies listed below:\n\n           Name             |         R.A. |       Dec.\n\n------------------------------------------------------------------------\n\n\nNGC6166                       | 16:28:38.23 | 39:33:04.4\n\nNGC4889                       | 13:00:08.13 | 27:58:37.2\n\nCB-11.4459                     15:18:32.09  |  31:09:40.82\n\n1200-07486009              | 15:12:12.73 |  31:54:36.17\n\nJ15122693+3224040\n<http://simbad.u-strasbg.fr/simbad/sim-id?Ident=%4012318336&Name=2MASX%20J15122693%2b3224040&submit=submit>\n    | 15:12:26.92 |  32:24:03.84\n\nJ151717.32+304801.3   | 15:17:17.33 |  30:48:01.33\n\nJ151303.42+325505.8   | 15:13:03.43 |  32:55:05.81\n\nJ15120209+3254551\n<http://simbad.u-strasbg.fr/simbad/sim-id?Ident=%402909607&Name=2MASX%20J15120209%2b3254551&submit=submit>\n    | 15:12:02.07 | 32:54:55.29\n\nJ15113637+3142477\n<http://simbad.u-strasbg.fr/simbad/sim-id?Ident=%4011050786&Name=2MASX%20J15113637%2b3142477&submit=submit>\n    | 15:11:36.34  | 31:42:47.31\n\nJ151109.81+313833.2   | 15:11:09.82  | 31:38:33.2\n\n\nThe KPED team thanks the National Science Foundation, the National Optical\nAstronomical Observatory and the Murty family for support in the building\nand operation of KPED.",
