    The time agrees with the Yaw direction of the -45 deg ASCAT antenna. However 
    the corresponding Pitch needed for this flare was -43.1 rather than -46.3 deg 
    (orientation of the antenna). I have noticed before that a brightening of 
    Metop often occurs with this Yaw direction even if Pitch doesn't agree. It 
    might be the supporting deployment structure of this antenna which could 
    produce extra flares. More observations are needed.
