 Solar activity is picking up (as noted by the noise bursts above). The
 flux near mid September was the highest for any Sept since 1974. If such
 levels can be maintained, the fall F2 VHF season may be the best in the
 last few years. (The flares associated with the solar noise bursts above
 did cause blackouts on h.f., i.e., D-region absorption of signals preven-
 ting their reaching the E or F layers).

 With this in mind, it is important that members who can monitor for
 US F2 effects (i.e., 33-MHz fire, 35-MHz pagers, etc.) carefully log
 and report the DX they get. Even approximate ID's (states etc.) are
 of some use in calculating MUF's.
