[quote:joinca:MV8xMzgyOTUyXzc2NTc1OTcyX0FDRkI2NzMx] Saturday, Dec. 14, 2019 [b]COSMIC RAY UPDATE: Something ironic is happening in Earth's atmosphere. Solar activity is low--very low. Yet atmospheric radiation is heading in the opposite direction. Cosmic rays percolating through the air around us are at a 5 year high.[/b] Take a look at these data gathered by cosmic ray balloons launched by Spaceweather.com and the students of Earth to Sky Calculus almost weekly since March 2015: Radiation levels have been increasing almost non-stop since the monitoring program began, with recent flights registering the highest levels of all. What's happening? The answer is "Solar Minimum"--the low point of the 11-year solar cycle. During Solar Minimum (underway now) the sun's magnetic field weakens and allows energetic particles from deep space to penetrate the Solar System. As solar activity goes down, cosmic rays go up; yin-yang. [b]When cosmic rays hit the top of Earth's atmosphere, they produce a spray of secondary particles and photons that rain down on Earth's surface. This is what our balloons measure--the secondary spray. We use X-ray and gamma-ray detectors sensitive to energies in the range 10 keV to 20 MeV. This type of radiation, which you can also find in medical X-ray machines and airport security scanners, has increased more than 20% in the stratosphere.[/b] The full article: https://spaceweather.com/ :hiding: [/quote]

We have just had another huge X flare measuring at a X8.2 originating from sunspot 2673
On September 11, 2017

ALL flares recorded ARE Earth facing regardless of where the sunspot is located
-----------
CME FROM X9 HAS ARRIVED!
Issue Time: 2017 Sep 07 2242 UTC
WARNING: Geomagnetic Sudden Impulse expected
Valid From: 2017 Sep 07 2255 UTC
Valid To: 2017 Sep 07 2330 UTC
IP Shock Passage Observed: 2017 Sep 07 2229 UTC
On September 6th we have had 2 X flares! A X2.2 at 09:10 utc & a secend larger flare just a few hours later of X9.3 at 12:02 utc. There is a large widespread Earth directed CME associated with this latest X flare as we can see here

An update as to the arrival time of this CME will be added once all data has been reviewed.
The X9.3 flare is the 14th largest X flare ever recorded!
On September 4th we had 7 M flares from fast growing sunspot 2673, with at least 1 large dense Earth directed CME. This CME will arrive late in the day on Wednesday September 6th.
There is now a 25% chance for X flares over the next 24hrs & 71% chance for M flares
We have a Long Duration M2.4 Solar Flare starting
01:05 UTC July 14th 2017
There was a full halo CME observed with this solar flare. The associated CME is Earth Directed. See discussion on the last page for all updates!
