    Solar storms cause large increases in atmospheric density at LEO orbital
    altitudes, resulting in large increases of drag on satellites; therefore,
    positional observers should expect satellites to be running early in the coming
    days.
    
    I recommend the following sites to follow the progress of the storm:
    
    This one reports geomagnetic activity, updated every 3 h. It shows that a very
    powerful storm has just begun:

    This site reports solar flux at various frequencies for the latest 7 days. It
    has been very high in recent days due to the recent smaller storms. It will be
    interesting to watch the effects of the present storm over the coming days:
