[PPRAANet] Where have all the sunspots gone?

[John Bloodgood]

Another good resource is https://www.swpc.noaa.gov/  .  The "Dashboards" have a good display of current status.  

Here is today's Solar Geophysical Activity Report:  

Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 347 Issued at 2200Z on 13 Dec 2019

IA.  Analysis of Solar Active Regions and Activity from 12/2100Z to
13/2100Z: Solar activity has been at very low levels for the past 24
hours. There are currently 0 numbered sunspot regions on the disk.
IB.  Solar Activity Forecast: Solar activity is expected to be very low
on days one, two, and three (14 Dec, 15 Dec, 16 Dec).

IIA.  Geophysical Activity Summary 12/2100Z to 13/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 416 km/s at 12/2345Z. Total IMF reached 6 nT at
12/2103Z. The maximum southward component of Bz reached -4 nT at
13/0439Z.

IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one, two, and three (14 Dec, 15 Dec, 16
Dec).

Subject: [PPRAANet] Where have all the sunspots gone?
 

We are about to set a new record for the lack of sunspots.  If we don't

get some short skip or have some coronal holes this weekend, the 

10-meter contest (which starts today local time) will have to be renamed 

the 10-meter ground-wave contest.

  From https://spaceweather.com/ yesterday:

"The sun has been blank (no sunspots) for 266 days so far in 

2019--including the last 29 days in a row. If this continues for only 3 

more days, 2019 will break the Space Age record for blank suns in a 

calendar year. The previous mark (268 spotless days) was set in 2008 

during an historically deep Solar Minimum. The Solar Minimum of 2019 is 

shaping up to be even deeper"

I used to religiously follow solar activity during the sunspot maxima.  

Some of the sites I went to were:

https://www.raben.com/maps/    (The sun is so blank, that it looked like

someone forgot to populate the sun with data).

https://dx.qsl.net/propagation/  I don't think the SFI can get much

lower than presented on this page.  And look at the Xray flux chart.  It 

looks like an ECG of a dead person.

http://sprg.ssl.berkeley.edu/dst_index/page1.html  This shows the

current geomagnetic-storm low is very low.

Only cosmic rays are increasing, because the CMEs that normally sweep 

them aside are nonexistent.

I know we're in a solar minimum, but this is ridiculous.
