The OGLE-IV Transient Detection System (Wyrzykowski et al. 2014, AcA,64,197; Kozlowski et al. 2013; Klencki et al. 2016, AcA, 66,15) announces discovery of 52 transients discovered in last three months.

They appeared near or on top of apparent galaxies or in empty fields with no counterpart down to I=24 mag. Their light curves resemble those of supernovae or cataclysmic variables. All of the candidates were detected with and selected from our Rapid Transient Detection System within less than 15 mins from observation and were made immediately available on the Rapid webpages: http://ogle.astrouw.edu.pl/ogle4/transients/rapid/rapid.html
