on 1 April and is current for 2-3 Apr. Maximum useable frequencies 
for HF communications are expected to be around predicted monthly 
values to slightly depressed today. The ionosphere may be slightly 
to moderately disturbed today and tomorrow due to weak geomagnetic 
storm possibly causing minor disruption in HF communication particularly 
at higher latitudes.
