Another overcast night visually - but again 
I think the cloud was thin enough for the 
SDI to discern direction information.  The 
wind and temperature data both look good.  
The CME launched on April 27 hit SOHO & ACE  
at 0800 and 0845 UT respectively.  Ground 
effects (mag, VHF radar) appeared about 0945. 
However, the ground impact was abysmal - no 
decent disturbance.
