Space Weather News for April 20, 2015

   High-latitude sky watchers should be alert for auroras this week when a solar   
   wind stream and a faint CME are expected to hit Earth's magnetic field in   
   quick succession.  NOAA forecasters estimate a 45% to 65% chance of polar   
   geomagnetic storms on April 21-22.   
       
   At the same time, Earth will be passing through a stream of debris from Comet   
   Thatcher, source of the annual Lyrid meteor shower.  Sky watchers are already   
   seeing a smattering of late-night fireballs as Earth approaches the diffuse   
   core of the debris stream.  Meteor rates are expected to crest on April 22-23   
   with as many as 20 Lyrids per hour.
