Photometric magnitudes measured for TUVO-21acq in the three UV bands used during the UVOT observations.

Outburst 1 Outburst 2

Filter Quiescence Peak Amplitude Peak Amplitude
UVW1 23.4 ± 0.3 19.3 ± 0.1 > 4.1 19.0 ± 0.1 > 4.4
UVM2 22.8 ± 0.2 20.4 ± 0.1 > 2.4 19.4 ± 0.1 > 3.4
UVW2 23.0 ± 0.1 19.5 ± 0.2 > 3.5 19.4 ± 0.2 > 3.6

Notes. All magnitudes are given in the AB system. Quiescence measurements were obtained using the summed images, which exclude images obtained during the outbursts. The errors are the 1σ statistical errors on the photometry added in quadrature with the systematic UVOT calibration errors, as given by uvotsource. The outburst amplitudes are lower limits because only the UWV1 detections are likely to have occurred around the outburst peak (see Fig. 3).
