2. FORECAST (06 MARCH - 12 MARCH)
Solar: 
Generally R0 level solar flare activity is expected over the
week of 06-12 Mar. There is a chance of R1 level activity
over this period due to several small active regions on the
solar disk with beta magnetic complexity.

Geomagnetic:  
Mostly G0 geomagnetic activity is expecter over the week of
06-12 Mar. There is a chance of G1 over 06-08 Mar due to 
anticipated coronal hole high speed wind stream effects.

Frequencies:  
MUFs are expected to be near predicted monthly values, with
enhancements of up to 15% for most of the week. MUFs may be
reduced over 08-10 Mar due to possible geomagnetic activity 
over 07-09 Mar.
