2. FORECAST (11 MARCH - 17 MARCH)
Solar: 
Predominately low, chance of M class flare activity (ASWAS R1-R2).

Geomagnetic:  
Geomagnetic storm may occur late on 13 March, with storm activity on 14 March, 
due to a coronal mass ejection late on 10 March, otherwise quiet to unsettled
conditions.

Frequencies:  
Ionospheric MUFs possibly depressed 15-30% 14-15 March in association with
possible
geomagnetic storm activity otherwise MUFs expected to be about near to 15% above

near predicted monthly values.
