Third weakest solar cycle since 1755

The Sun has been spotless for two weeks straight, says meteorologist Anthony Watts. This makes it the longest stretch with zero sunspots since April 2010

Solar cycle 24, the solar cycle we are now in, has been historically weak, says Watts. “There have already been 26 spotless days in 2017 (34% of the entire year) and this follows 32 spotless days last year which occurred primarily during the latter part of the year.

“The blank look to the sun will increase in frequency over the next couple of years leading up to the next solar minimum – probably to be reached in late 2019 or 2020.”

Third weakest solar cycle since 1755

“By one measure, the current solar cycle is the third weakest since record keeping began in 1755 and it continues a weakening trend since solar cycle 21 peaked in 1980.

“One of the impacts of low solar activity is the increase of cosmic rays that can penetrate into the Earth’s upper atmosphere and this has some important consequences.”

  1. Some food for thought. We’ve had weak cycles like this before and unfortunately during one of them with over 400 days without sunspots, the Carrington Event occurred. Let’s hope it’s just a cool down instead of that.

  2. 26 days is 34% of the days already passed this year (not of the entire year). Thus 26 divided by 78 multiplied by 100 equals 33.3% (includes Sunday 19th March).

  3. 15 days today
    2009 was THE biggie for absence prior
    i found it funny then as it was the COP event
    raving warming then as we reached a solar low.

    with weakening mag fields ON earth as well as the battering the thinning shield around us is getting, incoming increases in radiation etc
    anything large CME wise sure would knock us around;-/

  4. See, 17 days spot less , with four years yet to run in this solar cycle.
    Eventually Anthony Watts will have to accept that this cycle 24 and the next SC25 for part of the predicted Grand Solar Minimum, as predicted by Landscheidt.

  5. Gotta love the selective application of science here. Great read and whoever writes here should really start writing for the onion.

  6. No sign of any cold weather here in Lowestoft. Not even getting frosts now. Arctic sea ice look as though it has peaked at its lowest ever level on record. Could be that sea surface temperatures haven’t responded to lower solar activity and it might take 2 or 3 yrs then I think it will turn much colder.

  7. Hi Paul,

    If you look at this site:
    Daily Mean Temperatures in the Arctic 1958 – 2017
    For the 2017 spring period you should be able to notice the peaks of less cold and the dips towards mean, and then look at the 2016 page, you should be able to see similar peaks and troughs for the previous spring period and the violent peaks and troughs prior the end of year in 2016.
    This activity is due to Meridional Jet Streams driving warm wet air into the Arctic Ocean region, around Scandinavia and then driving south into Central Europe and Middle East dumping vast amount of snow as it went. This air stream has been stuck for weeks on end with a few week breaks in between the next stuck session.
    Indecently the first early winter peak were the remains of the last Hurricane of the season, which parked its self on Greenland and dumped vast quantities of snow in the process.
    The source of the Meridional nature of the Jet streams is reduced EUV from the Sun, the source of the Heat was the recent high strength El Nino. With the worlds heat engine following its normal process of moving heat from a hot zone to a cold one where it is radiated into space via IR radiation and giving us weather in the process.

  8. I’m looking for a drop in temperature in Tropical waters as it contains the most energy to feed upon. It’s looking like another El Niño this summer is in the cards. Remember this too that the oceans store 1000 times more heat energy than the land does. So how does an ice age begin? I think we are seeing the very beginnings of it right now. First, it’s always hottest before the cold one just has to look towards colonial America. You had the droughts in France and heat waves that were leading to the French Revolution yet, in winter the cold was so brutal in the US even the Delaware River was freezing over completely so Washington could cross it. Remember too Russia during this time was having particularly brutal winters. When Napoleon did try to invade Russia the Russians didn’t even bother fighting. They burnt down every available resource and let the poorly equipped French troops freeze to death. Our future is written in our past all you gotta do is look for it.

    So we have had increased volcanic activity and lowered solar activity. The solar minimum has already had a profound effect on Texas in 2014 and California this year by ending massive droughts. The cosmic rays rode in with atmospheric compression events ending really damaging droughts. This year we have a record snow extent for the Northern Hemisphere due to the Meridonal Jet Streams. They say that the oceans trail solar activity by about a decade give or take. For the oceans to lose that latent heat the water vapor must fall as precipitation so enjoy the upcoming massive storms that in the short term will just keep breaking records.
