(GCN 24191) and Anand et al.\n(GCN 24311) starting at 9:13:24 UT on 2019-04-27.\n\nThe measurement of ZTF19aasckkq is consistent with Perley et al. (GCN\n24314) and we report upper limits for the rest of the transients.\nMagnitudes are derived after calibrating against PS1:\n\n  ID                            JD RA         DEC magnitude\n\nZTF19aasckkq    2458600.9291 248.413102  13.910183 r = 20.29 +- 0.18\n\nZTF19aaskbzh    2458600.9541 206.393046  69.329244 r > 19.65 +- 0.03\n\nZTF19aasejil       2458600.9837 261.945810    1.653720 r > 20.38 +- 0.34\n\nZTF19aasckkm   2458600.9248 247.302345  12.930679 r > 19.79 +-  0.18\n\nMore observations for this objects are scheduled.\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.",
