    And just to add to that Kevin , its a rather worrying time for operators of older high traffic birds. 
    There have been situations in the past where operators have closed down a number of transponders carrying "marginal" broadcasts during  the night to try and reduce the load on internal batteries. 
    
    I'm still stuck under this Orwellian cloud....which seems to be going on forever , so I'll have to rely on the RF effects at the peak of the outage period to check just how intense it is.
