The sun has been blank for 32 consecutive days, a stretch that enters the SIDC record books as one of the longest ‘periods with spotless days’ since 1849, and it ain’t over yet. In addition, the highly active region turning around the limb –expected to spoil the party this week– has turned out to be “all sizzle”.
All sizzle, and no sunspot, writes Dr Tony Phillips of spaceweather.com. We expected a sunspot. Instead, we have plage. French for “beach,” a plage is the bright magnetic froth that surrounds many big sunspots. In this case, however, there are no sunspot:
Dr Phillips continues: This frothy network of white-hot plage is emerging over the sun’s northeastern limb underneath a canopy of sizzling magnetic arches. Usually, such a canopy would herald an active sunspot group. So far, however, no dark cores are visible, he writes.
The sun has been blank for 32 days and counting, which sees it enter the SIDC record books as one of the longest ‘periods with spotless days’ since 1849:
As visible in the above SIDC table, recent years are increasingly making the mark.
The Solar Minimum of Cycle 23 (2008-09) was the deepest of the past 90 years: referring to the table above, the minimum achieved a 32 spotless day run between July 31 and Aug 31, 2009; as well as a 31 day run between July 21 and Aug 20, 2008.
The Solar Minimum of Cycle 24 comfortably surpassed Cycle 23 in both weakness and duration: the minimum achieved an impressive 40 spotless day run between Nov 14 and Dec 23, 2019 and then a 34 day run between Feb 2 and Mar 6, 2020.
Today’s stretch of 32 spotless days is potentially even more impressive though: this year, solar Cycle 25 has shown clear signs of firing-up but the fact that we’re still able to experience a month-long spell of blank solar discs is quite remarkable. SC25 should be upon us, yet instead we’re suffering an extended and historically prolonged Solar Minimum. This all further supports the forecast that the period we’re entering is indeed the next ‘full blown’ Grand Solar Minimum:
This interval has pushed the current Solar Minimum into historic territory, writes Dr Phillips. Since 2016, there have been 825 spotless days. To find a lull in the solar cycle with more spotless days, you have to go back to the years around 1913 when the sun racked up 1023 spotless days (the years around 1913 fell within the Centennial Minimum).
We are now experiencing a century-class Solar Minimum, concludes Dr Phillips.
The COLD TIMES are returning, the mid-latitudes are REFREEZING, in line with historically low solar activity, cloud-nucleating Cosmic Rays, and a meridional jet stream flow. Both NOAA and NASA appear to agree, if you read between the lines, with NOAA saying we’re entering a ‘full-blown’ Grand Solar Minimum in the late-2020s, and NASA seeing this upcoming solar cycle (25) as “the weakest of the past 200 years”, with the agency correlating previous solar shutdowns to prolonged periods of global cooling here.
Prepare for the COLD— learn the facts, relocate if need be, and grow your own.
