December 2016

Propagation Summary
on 07 Oct Solar activity was at very low levels with a few background flares observed.  The Solar Flux was at high levels on Oct 10-11, 16-18.
Geomagnetic field activity was mostly unsettled to active 03-05 Oct. A minor storm was observed early on 04 Oct. Mostly quiet levels were observed from 04-09 Oct with unsettled and active periods 07 and 08 Oct. The enhanced activity was due to coronal hole activity. Unsettled conditions prevailed 11-18 October
Propagation Forecast
Solar activity is expected to be at very low levels with a chance for C-class flare activity throughout the outlook period.   The solar flux is expected to be at high levels on 24-26, 30-31 Oct and 01-06 Nov, increasing to very high levels on 27-29 Oct. This is due to Coronal Hole High Speed Streams. A lesser disturbance is likely on 11-12 November.  Normal to moderate levels are expected for the remainder of the outlook period.
Geomagnetic field activity is expected to be at unsettled to active levels on 23-31 Oct and 01 Nov. G1 (Minor) field activity is possible on 23-31 Oct with G2 (Moderate) levels possible on 24-26 Oct. This activity is due to the anticipated influence of multiple, recurrent CH HSSs. Generally Quiet to unsettled conditions are expected for the remainder of the outlook period. 
The quietest days, propagation –wise are likely to be November 2-10.

Meteor Showers 
November 4-5 2016, South Taurids, November 11-12 2016 North Taurids, November 16-17, 2016 Leonids. December 13-14, 2016 Geminids.
The next propagation report will be in January.  Regular updates are posted on the BDXC News email group via Mike Terry. You can also subscribe to email alerts here:
