> One of the most powerful solar flares of the current solar cycle, rated at X4.9, erupted at 0057 UTC on Tuesday. Now comes this bulletin from the Geophysical Institute at the University of Alaska Fairbanks:

> 
> A very large solar event took place early on the 25th of February.  It  
> was located near the east limb of the sun facing away from the Earth,  
> so the effect on the Earth may be diminished somewhat.  However, we  
> expect enhanced auroral activity when the disturbance arrives late in  
> the evening of the 26th of February UT.  For North America, this means  
> aurora may reach index Kp=5 or more so as to be visible over the  
> northern half of the US during the night of the 26th/27th.  Activity  
> could also be high on the night of the 27th/28th.
