    Hi Marcus,
    it is not yet clear to me what the maximum distance for NOSS flares can be, but 500 km is absolutely too far.
    I think it is reasonable to expect a brightness increase of a few magnitudes up to 100 km from the flare track.
    Best Regards,

    > Hi!As Bjoern has pointed out, SkyMed gives visible NOSS flare prediction from Torquay UK (50.5 N, 3.5 W) today about 19:28 UTC if I input the txt file from the flare tracker website and set Maximum Distance to 525km.
    >  Is 525km an appropriate value and could you explain how the Max Distance value should be determined? Is it simply related to the height of the objects orbit or is it more to do with the horizon, or both?
