The Swift Ultraviolet/Optical Telescope (UVOT) and X-Ray Telescope (XRT) observed supernova 2007gi on the 3rd August and managed to measure the UVOT magnitudes:
v = 14.6±0.1 (79 seconds exposure time)
b = 15.0±0.1 (157 seconds)
u = 15.2±0.1 (157 seconds)
uvw1 ((181-321nm) = 17.2±0.2 (472 seconds)
uvm2 (166-268 nm) = 20.1±0.5 (875 seconds)
uvw2 (112-264 nm) = 18.5±0.2 (621 seconds).
