Propagation Forecast up to 16 September
Solar activity is expected to be at low levels from 03-07 September with a chance R1and R2 (Minor to Moderate) activity from 08-16 September.
The Solar Flux is expected to reach high levels from 01-07 Sep, 11-13 Sep, and again from 15-16 Sep due to recurrent Coronal Hole High Speed Stream (CH HHS) activity.
Geomagnetic field activity is expected to be at unsettled to active levels from 8-9 Sep and 13-16 Sep due to recurrent CH HHS activity.  In conclusion the calmest HF conditions should be on Sep 3-7 and 10-12, and the most disturbed days are likely to be Sep1-2 and 14-16.
