K-Index 7 (as shown for 'College') is pretty high I think, but the others - including 'estimated planetary' - are still at 6, wich is strong but not the end of the world. Happened earlier this year already.

Forgot to post the current sidc ticker:
The latest video from Adapt 2030 relates to this topic:
More signs that a dramatic shift is occurring in our atmosphere - and in those of other planets in our solar system. Some related articles published on SOTT include:
- Astonishing discovery: First-ever 'space hurricane' was observed in upper atmosphere above North Pole in 2014
- Super-cold thunderstorm sets temperature record, scientists note increase in last 20 years
- Cosmic climate change: 'Space plasma hurricane' observed in ionosphere above North Pole!
- Huge uptick in lightning over the Arctic in past decade
- Newnan tornado was only 10th rare EF4 twister in seven decades for Georgia
- Novel atmosphere phenomenon 'STEVE' makes ANOTHER appearance over Finland
- Pluto's strange atmosphere appears to have collapsed
- Astronomers have spotted a new type of storm on Saturn

Just for the record: There was a strong but short lived impact early on 25th (Something on 26th as well, don't know if that was from the same solar event).

Thanks for posting this information, mrtn.
KP7 scale is equivalent to a level G3 geomagnetic storm which can produce power outages, GPS problems, transformer failures/fires. Thinking with all the turmoil, folks who aren't familiar with Space Weather may spread rumors.
I'm linking a YouTube report from Ben Davidson.
Also a link from NOAA showing the various effects on systems of geomagnetic storm levels and how they relate to the KP index measurements. I find the PDF scale particularly helpful for understanding and highly recommend taking a look it if anyone hasn't seen it before:

When I click the link it shows a different Scale. Please click on the one that says "Geomagnetic Storms." That's the one I find most helpful. Sorry for the confusion!Thanks for posting this information, mrtn.

Is the Earth's magnetic field far weaker than we realised?
This is discussed in the recent article from electroverse.com:
The full article can be found here on sott.net:
Earth's magnetic field just struggled with a weak CME: Sign of the times
SLEEPING SUNSPOT WAKES UP: Formerly quiet sunspot AR2824 is suddenly crackling with solar flares. It's almost hyperactive. NASA's Solar Dynamics Observatory recorded seven C-class flares and two M-class flares during a 12-hour period on May 22nd:
These rapidfire explosions have hurled multiple overlapping CMEs into space. NOAA analysts are still untangling the clouds to determine if any might hit Earth. So far, none appears to be squarely Earth-directed, but glancing blows are possible in the days ahead. Stay tuned for updates.
The flares are strobing Earth with pulses of ultraviolet radiation. Waves of ionization rippling through Earth's upper atmosphere are causing intermittant shortwave radio blackouts. The deepest so far occured over North America on May 22nd (~1715 UT) during an M1.1-class flare: map. Ham radio operators, aviators and mariners might have noticed unusual propagation at frequencies below ~20 MHz. Solar flare alerts: SMS Text.
Cosmic Rays Solar Cycle 25 is beginning, and this is reflected in the number of cosmic rays entering Earth's atmosphere. Neutron counts from the University of Oulu's Sodankyla Geophysical Observatory show that cosmic rays reaching Earth are slowly declining--a result of the yin-yang relationship between the solar cycle and cosmic rays.
Oulu Neutron Counts
Percentages of the Space Age average:
today: +9.5% High
48-hr change: +1.0%
Max: +11.7% Very High (12/2009)
Min: -32.1% Very Low (06/1991)

heterodyne is a signal frequency that is created by combining or mixing two other frequencies using a signal processing technique called heterodyning, which was invented by Canadian inventor-engineer Reginald Fessenden.[1][2][3] Heterodyning is used to shift one frequency range into another, new frequency range, and is also involved in the processes of modulation and demodulation.[2][4] The two input frequencies are combined in a nonlinear signal-processing device such as a vacuum tube, transistor, or diode, usually called a mixer.[2]
In the most common application, two signals at frequencies f1 and f2 are mixed, creating two new signals, one at the sum of the two frequencies f1 + f2, and the other at the difference between the two frequencies f1 − f2.[3] The new signal frequencies are called heterodynes. Typically, only one of the heterodynes is required and the other signal is filtered out of the output of the mixer.
