Abstract

The blazar, OJ287, underwent a predicted period of flaring in late 2015, triggering multiple observing campaigns to conduct intensive monitoring. We present the polarisation data taken during this event with the Ringo3 polarimeter on the Liverpool Telescope and discuss two possible causes of the flares.
