COMMENT: Ionospheric support for HF propagation is expected to 
remain near monthly predicted values. The 10.7 cm solar flux 
was 123 on June 19 but may increase further as the next major 
solar active region continues to rotate around the south east 
limb. This may lead to a small increase in ionospheric support 
for higher frequencies.
