Large outburst detected in August 2007

Comparison of photometry taken by Albert Sanchez (MPC 442) and photometry taken by Donatus Narbutis with the IAC-80 Telescope at Teide Observatory (Tenerife, Spain) shows the extent of this outburst and the change in colours and the Spectral Energy Distribution. V has brightened from its normal level around V=16 to V=13.2. At the same time the colours have become very much bluer. The spectral energy distribution shows that the spectral index has effectively inverted with the flux declining to the red.
