What was significant in the recently published study was how the radiocarbon content of trees in Lapland differed from that of trees at lower latitudes.

The Sun’s Little-Known 100-year “Gleissberg Cycle” is Waking Up
You’ve probably heard of the 11-year sunspot cycle. The Gleissberg Cycle is a slower modulation, which suppresses sunspot numbers every 80 to 100 years. For the past ~15 years, the…
Major (and unusual) Solar Flare and CME
h/t Roy W. Spencer March is a peak month for auroras, and this should be a good one in the coming days. A strong X-class solar flare lasting 5 hours…
New Sunspot may Hurl Dangerous Solar Flare at Earth
SpaceWeather reports: One of the biggest sunspots in years has just rotated over the sun’s northeastern limb. AR3112 has a mixed-polarity magnetic field that harbors energy for strong X-class solar…
The Solar Storm That Nearly Sparked A Nuclear Confrontation
On May 23rd, 1967, a solar storm took place that was so powerful, it jammed radar and radio communications in polar regions and the US Air Force actually began to…
X-Class Solar Flare
Even though the responsible sunspot was located behind the edge of the sun, enough radiation reached our planet to cause a strong shortwave radio blackout.
Massive X-CLASS SOLAR FLARE Hurls a CME Towards Earth
Via SpaceWeather.com Earth-orbiting satellites have just detected an X1.3-class solar flare (March 30 @ 1737 UT). The source is active sunspot AR2975–the same sunspot that has already hurled at least two CMEs toward…
Huge sunspot may launch solar flares toward Earth in the next two weeks
One of the biggest sunspots in years is emerging on the sun today. Hours ago it produced a C-class solar flare and a minor radio blackout over the Indian Ocean.…
The Carrington Event: September 1st, 1859
In fact, it was this same time of year back in 1859 when a super solar storm – now known as the “Carrington Event” – took place during another weak…
NASA sun data helps new model predict big solar flares
Using data from NASA’s Solar Dynamics Observatory, or SDO, scientists have developed a new model that successfully predicted seven of the Sun’s biggest flares from the last solar cycle, out…
NASA’s SDO Sees New Kind of Magnetic Explosion on Sun
from NASA Dec. 17, 2019 NASA’s Solar Dynamics Observatory has observed a magnetic explosion the likes of which have never been seen before. In the scorching upper reaches of the…
This kind of solar storm could be devastating in today’s world…”The Carrington Event” of 1859
Guest post by Paul Dorian Overview The sun continues to be very quiet and it has been without sunspots this year 70% of the time as we approach what is…
Three solar storms headed for Earth
NOAA forecasters say there is a 55% to 60% chance of geomagnetic storms on May 15th and 16th when a series of coronal mass ejections (CMEs) could hit Earth’s magnetic…
Huge new sunspot may hurl flares towards Earth
Sunspot AR2736, which hurled a Coronal Mass Ejection toward Earth yesterday, is growing larger and crackling with C-class solar flares. The active region now sprawls across more than 100,000 km…
Monster solar storm that hit Earth discovered in the past
Something this big today would surely fry electrical grids, GPS, and communications. It may be bigger than the Carrington Solar event of 1859. Scientists have found evidence of a huge…
Declassified report shows solar flares detonated mines
By Jonathan Griffin A strong solar storm in 1972 caused widespread disturbances to satellites and spacecraft, and may have led to the detonation of mines during the Vietnam War, according…
Bad timing: Solar flares disrupted radio communications during September 2017 Atlantic hurricane relief effort
From the AGU: WASHINGTON — An unlucky coincidence of space and Earth weather in early September 2017 caused radio blackouts for hours during critical hurricane emergency response efforts, according to…
New discovery – 'magnetic cages' on the sun sometimes save us from massive solar eruptions
NASA’s SDO Reveals How Magnetic Cage on the Sun Stopped Solar Eruption A dramatic magnetic power struggle at the Sun’s surface lies at the heart of solar eruptions, new research…
SUNSPOT EXPLODES, HURLS GIANT SOLAR FLARE AT EARTH
We first reported on this possibility a few days ago. On Feb. 12th, the magnetic canopy of sunspot AR2699 exploded–for more than 6 hours. The slow-motion blast produced a C1-class solar flare and hurled…
Study: When the sun pulses X-rays, Earth’s ionosphere pulses in sync
A team of scientists led by solar physicist Laura Hayes investigated a connection between solar flares and Earth’s atmosphere. They discovered pulses in the electrified layer of the atmosphere –…
