Swift observations of ASSASN-16oh
Abstract
We report on Swift observations of ASSASN-16oh. This is a transient near the Small Magellanic Cloud that was first reported in ATel #9859. Observations began 2016-12-15 10:25:45 UT. The following UVOT magnitudes were measured: v = 16.8 +/- 0.1 (79 s exposure time), b = 16.9 +/- 0.1 (78 s), u = 15.5 +/- 0.1 (79 s), uvw1 = 15.0 +/- 0.1 (157 s), uvm2 = 14.9 +/- 0.1 (247 s), and uvw2 = 14.9 +/- 0.1 (315 s). These magnitudes are reduced using the method outlined for the Swift Optical Ultraviolet Supernova Archive (SOUSA; Brown et al 2014, Ap & SS, 354, 89) on the Swift/UVOT Vega-based photometric system (Poole et al. 2008, Breeveld et al. 2011).
