The Sun is Still Active

The sun has been active after the Fall Equinox. Not a lot of sunspots, but lots of geomagnetic activity.
A and K Indices have been elevated for a couple of weeks. The result is some nice propagation on 10 Meters at times. October usually is a good month in years of high solar activity. It looks like it won't disappoint us.
All of the following maps are 24 hour captures on 10-Meter WSPR.
I took a few days off.

10/12/2016 Nice opening to Australia and New Zealand.
10/13/2016 Despite a G1-G2 Geomagnetic Storm.
 I have been off for a few days. Despite low solar activity, it is still open.

I am always amazed how the band changes day to day. Yesterday, VK, ZL & an E5 filled the waterfall during the afternoon.

The Sun has been quiet for the remainder of November. There has been a couple of days with activity, but overall DX has been limited.  Today the first good Fall/Winter opening on 10-Meters occurred. For about 6 hours there was occasional paths in all directions. I strongly believe that meteor showers are an influence. It isn't a meteor that causes it, but residual ionization left by them that stirs up the Es layer.

I have replaced the desktop computer running WSPR and have had issues with the rig interface. Meanwhile in order to utilize the computer, I have switched back to PropNET (PSK31 Realtime Propagation Reporting).
5 Days

7 Days.
F2 opportunities were nil as solar activity was very low. I would call this propagation chordal interaction of the E and F layers. Openings were short in duration, but pretty good when it opened up. They occurred usually late morning, mid-day and late afternoon.
I noticed that some of these openings occurred just prior to a geomagnetic disturbance. Despite low sunspot numbers, several large coronal holes continue to produce streams to later disturb the ionosphere. Trans-Equatorial propagation is a usual result.

As I have said many times...
Don't give up on this band.
