2. FORECAST (08 MAY - 14 MAY)
Solar: 
R0, with a chance of R1 solar flare activity is forecast for 
08-May, increasing to R1, with a chance of R2 on 09-May as 
a probable active region rotates onto the front side of the
solar disk. R1, with a chance of R2 is then forecast for the
rest of the week due to this region.

Geomagnetic:  
G0, with a chance of G1 is forecast for 08-May due to 
geomagnetic activity from a recurrent coronal hole. G0 is 
forecast on other days this week.

Frequencies:  
Maximum Usable Frequencies may become depressed by 10-15% 
on 08-May. MUFs near predicted monthly values on other days.
