In terms of monthly mean sunspot numbers, solar activity is pretty much on the floor with February and July this year both seeing a mean SSN under 1.

How's that graph trending, over a couple decades?
(acknowledging how tiny a few decades is, to the sun)

Edited graph to include back to January 1960, see post above.

Interesting update to this chart tracking SC24, only runs to Jan 2019 and is a 13 month smoothed mean so the past few quiet months are not represented. Our current progression (SC25) is shown on the green line.

We've now matched 2009 as far as percentage of spotless days, will be interesting to see if we match 2008 next week.

Tell me about it, not a good time for Amateur radio Propagation, though there are good openings at times, a few weeks ago I was chatting away to a Guy in Chile and Brazil the other night all with just 100 watts of RF !

' 2019 IS A DEEP SOLAR MINIMUM: Today, the sun racked up its 198th spotless day of the year. So far in 2019, the sun has been blank 73% of the time. This is the same percentage as the year 2008--previously the least sun-spotty year of the Space Age. If Solar Minimum continues to deepen, 2019 will soon claim the undisputed throne of Space Age spotlessness, marking it as a century-class minimum in solar activity. '

Also from spaceweather, the previous record for cosmic rays was set in late 2009-early 2010.


Quote:
COSMIC RAYS ARE NEARING A SPACE AGE RECORD: Solar Minimum is underway, and it's a deep one. Sunspot counts suggest it is one of the deepest minima of the past century. The sun's magnetic field has become weak, allowing extra cosmic rays into the solar system. Neutron monitors at the Sodankyla Geophysical Observatory in Oulu, Finland, show that cosmic rays are percentage points away from a Space Age record:

DEEP SOLAR MINIMUM: Solar Minimum is underway, and it's a deep one--perhaps the deepest of the Space Age. So far this year the sun has been without sunspots 73% of the time, matching the record previously set in the year 2008. If the sun remains blank for the rest of this week, 2019 will edge past the Space Age record for sustained spotlessness. Keep an eye on the spotless days counter for updates.
