Abstract:
We report observations of the blazar AO 0235+16 with the Large Array Survey Telescope (LAST) during 3 nights, following-up recent reports of optical brightening.

We report the observations of the flat-spectrum radio quasar AO 0235+16 (aka PKS 0235+164) at redshift z = 0.94 (Hewitt and Burbidge, 1989) with the Large Array Survey Telescope (LAST, Ofek et al. 2023). The source was recently reported brightening in the optical band (#ATel16190, #ATel16199 #ATel16204).

We observed the source with no filter (clear) for 3 nights on 22, 26 and 27 August 2023. The reported magnitudes are in the LAST native AB system, calibrated relative to the GAIA-DR3 Bp band. 

From a preliminary analysis of the night of August 22, we measure a peak flux for the source of M = 16.24 +/- 0.04 at MJD 60179.06385. The source was then observed in a fainter state on the nights of August 26 and 27, with an average flux of M = 17.85 +/- 0.03 (MJD 60182.97444) and M = 17.81 +/- 0.03 (MJD 60184.00418), respectively.  All errors include statistical and calibration errors.
