2. FORECAST (28 AUGUST - 03 SEPTEMBER)
Solar: Moderate activity possible for 28-29 August as recent
active region 2403 transits of the visible disk. Otherwise Low
solar activity expected.

Geomagnetic: Active to possible Storm periods on 28Aug-29Aug 
due to coronal hole effects. Otherwise Quiet to unsettled on 
other days.

Frequencies: MUF's depressed by 20%-40% for the forecast week 
due to recent persistent Active geomagnetic conditions. 
Ionospheric recovery expected to be slow due to Low solar activity.
