Following the report in Atel#8618 of brightening of Delta Sco to V=0.8 on 31 Jan 2016, , I carried out aperture photometry on data from the Liverpool Telescope All Sky Camera (SkyCamA). The comparison star used was Beta Sco, for which a magnitude V=2.50 was adopted.

SkyCamA takes a 30 second exposure of the whole sky as visible from La Palma once per minute.

A sample of frames were examined taken at 05:16, 05:36, 06:00, 06:46 and 06:56UT. Delta Sco has magnitude V=1.8 +/- 0.2 in all frames, similar to recent historical values.
