    On the 10th of January I have observed a bright flare from the
    GOCE (09-013A) satellite. 
    
    The flare was very short, red like Aldebaran, and at its
    maximum, I am quite sure, even brighter than the star. 
    I would estimate the magnitude to about 0.5 or even 0. 
    
    The flare occurred at 16:52:31 ± 0.5 s (UTC) on 10/01/2010.
    
    By using a Vertical-Along Track coordinate system, the 
    flaring surface orientation should be defined by:
    
    Angle: 93.4° +- 0.3°
    Tilt: 22.6°
    
    These angles are consistent with those already obtained by
    Marco Langbroek. 
    
    If these results are correct, they may indicate that the
    satellite is actually stabilized about 3.5 degrees off the
    orbit plane and toward the sun direction.
    
    I have created a workspace for predicting future GOCE flares.
