I confirm there is nothing in the picture I made with the Bradford Robotic Telescope this night, i.e. V<17.0 (unf) May 16.0618 as I reported on the AAVSO website. The quality of this picture is poor but the field of the stars is similar as other days... Can the outburst be so fast (almost 3. mag in 5 hours)? Regards, Franck.
