The 2 main characteristics of these events are their high degree of polarisation and indications that the OH flaring zones are more internal than the standard OH ones. This latter fact has been confirmed by recent mapping. These flaring events have now being recorded towards objects believed to be isolated as well as belonging to a binary system. The overall characteristics of such events and the implications with respect to the standard models will be discussed.1 - Video1 - DigitaleenFlaring MirasMultimediahttps://www.eso.org/sci/meetings/2015/STEPS2015.htmlFIS/05 - ASTRONOMIA E ASTROFISICA
