GCN Circular 16362
D. A. Perley and L. Singer (Caltech) report on behalf of a larger collaboration: We re-imaged the same ten P48 fields near the center of the error circle of Fermi trigger 423717114 (Singer et al., GCN 16360) between 09:28:30 through 09:42:30 UT on the night of 2014-06-07. iPTF14bfw and iPTF14bga have not faded relative to our observations during the previous night. For iPTF14bgc, we measure R = 20.68 +/- 0.21, consistent with the point-like counterpart in our reference images but significantly fainter than the previous night. A power law fit to the decay gives a temporal index of alpha = -1.1 +/- 0.1. We do not detect iPTF14bfu in our P48 image with a limiting magnitude of R ~ 21.1. Further imaging was obtained with the Palomar 60-inch telescope on two epochs, starting at 07:47:45 and 10:47:31, respectively. We acquired a series of seven 180-second images in r-band and five 180-second images in i-band in the first epoch, and a series of seven 180-second images in r-band during the second epoch. We detect the transient in a combined stack of all exposures in each band/epoch. Calibrating relative to USNO-B1.0 stars in the image, we measure magnitudes of: r = 21.1 +/- 0.2 (t_mid = 28.78 hr) i = 21.0 +/- 0.3 (t_mid = 29.12 hr) r = 21.4 +/- 0.2 (t_mid = 31.78 hr) Relative to the magnitudes presented by Singer et al., these observations suggest an average temporal index of only alpha~-0.5, much slower than observed during the first night. Further observations are ongoing.
