heal.abstract	Rapid variability in the light curves of Type Ia supernovae (SNe Ia) has the potential to provide a better understanding of nearly every aspect of SNe Ia, from their explosion physics to their progenitors. We present results of highcadence monitoring of the optical light curves of three bright SNe Ia: 2016gsn (ASASSN16la), 2016gfr and ASASSN16kz (2016gsb) using the RISE2 camera on the 2.3m Aristarchos telescope to search for rapid variability. The supernovae were monitored over four nights with a cadence of 1060s and high precision differential aperture photometry was derived. Differential light curves with respect to all comparison stars available on each night, as well as reconstructed light curves after implementing the Trend filtering Algorithm (TFA; Kovacs et al. 2005) are presented. We derive the decline rate of each supernova on each night and quantify the precision of our photometry and variability in the light curves, after accounting for sources of systematic error. We encourage further highcadence photometric monitoring of bright SNe Ia with the goal of investigating the intraday behaviour of their light curves.	en
