We triggered Swift to observe the young type Ia supernova iPTF16abc (ATel#8907, ATel#8909) under our ToO program (PI: Kasliwal; program ID: 1215232). The first visit was undertaken around UT April 5.4, about 12 hours after our trigger. The UVOT photometry (in AB system) is as follows:
UW2 > 22.45
UM2 > 22.99
UW1 = 21.76 +/- 0.34
U = 19.24 +/- 0.11
V = 18.37 +/- 0.24
B = 18.88 +/- 0.13
The supernova is not detected by XRT, leaving a 3-sigma upper limit of 4.26e-3 cts/s.
More Swift observations are scheduled in the next few days.
