Why don't we hear more about what Geomagnetic Storms (often from the sun) do to technology on earth?

I can't speak for the whole world but in the U.S. it is about liability. So, it is not in the interests of any company big or small to tell the public something bad has happened unless it is something like a severe power outage that affects everyone locally. And even then they say as little as possible.

So, whether it is hacking or the sun or Geomagnetic storm or solar storm (just expect many more problems electronically now that our magnetosphere is so compromised so many places on earth and also expect ongoing genetic damage to some of the life on earth exposed to these cosmic rays and solar storms etc.

But, don't expect to hear much about it because companies and even governments usually stay pretty mum. Now, with Trump they are busy erasing all scientific knowledge about Global Warming for instance and getting rid of government paid scientists to study this kind of thing. Which is crazy because this just means millions are going to die worldwide during the next century but that's what's happening in the Trump administration now.

So, don't expect governments to tell you anything or companies either for that matter.

CASSINI DIVES TOWARD SATURN: Next month, NASA's Cassini spacecraft will end its 13-year mission to Saturn by plunging into the body of the ringed planet. But first.... Cassini is going to skim the atmosphere of Saturn five times. This will alter the spacecraft's orbit in preparation for its suicide plunge while giving researchers an opportunity for point-blank study of the planet's gases. The first graze occurs on Aug. 14th. Get the full story from JPL.
A HOLE IN THE SUN'S ATMOSPHERE: A hole has opened in the sun's atmosphere and it is turning toward Earth. NASA's Solar Dynamics Observatory is monitoring the structure, which straddles the sun's equator just behind sunspot AR2670:
This is a "coronal hole", a region where the sun's magnetic field has peeled back and allowed gaseous material to escape. A stream of solar wind flowing from this hole should reach our planet during the early hours of August 12th. Enhanced magnetic fields at the leading edge of the stream will interact with our planet's magnetosphere, possibly sparking mild geomagnetic storms.

Coincidentally, the solar wind will arrive during the peak of the Perseid meteor shower. High-latitude sky watchers might detect the green glow of auroras in their photos of disintegrating meteoroids. Free: Aurora Alerts
SOLAR ECLIPSE IN A VEGETABLE STEAMER: During the Great American Solar Eclipse on Aug. 21, 2017, only a narrow slice of the USA will experience totality--the magical moment when the disk of the Moon completely covers the sun. The rest of the country will see a partial eclipse. But wait. How do you actually see it? Believe it or not, you probably already own a partial solar eclipse viewer. Just go into your kitchen and find the vegetable steamer. John Stetson of Maine demonstrates:
"During the eclipse on the 21st, sunbeams projected through holes in the steamer will appear as crescents," says Stetson. "It will be a good day to walk around with your vegetable steamer."

"The Chinese were the first to record the use of pinhole projection to observe eclipses in 500 BCE," he adds. "At the beginning of Western Civilization, Aristotle also wrote about this phenomenon."
Don;t have a vegetable steamer? Colanders work, too! Even a tree will do the trick.  Sunbeams lancing through gaps in the leafy canopy form crescent shaped spots on sidewalks and other surfaces. "Here is my son, Charley, standing behind a bush on June 10, 2002 during a partial eclipse," says Stetson. "Crescents may be seen projected onto his shirt."
SOLAR ECLIPSE PENDANTS: Would you like to support our Solar Eclipse Balloon Network? Here's one way: Buy a space pendant. This solar eclipse-themed necklace flew to the stratosphere on July 2, 2017, attached to the payload of an Earth to Sky Calculus space weather balloon:
The payload contained more just like it. If you buy one now for $89.95, we will fly it back to the stratosphere during the Great American Solar Eclipse on August 21, 2017, where it will be enveloped by the Moon's cool shadow above our launch site in Oregon. No additional charge! Just make a note in the COMMENTS BOX of the shopping cart: "Please fly my pendant into the eclipse!" Each pendant comes with a greeting card showing the jewelry in flight and telling the story of its journey to the stratosphere and back again.

All Sky Fireball Network
Every night, a network of NASA all-sky cameras scans the skies above the United States for meteoritic fireballs. Automated software maintained by NASA's Meteoroid Environment Office calculates their orbits, velocity, penetration depth in Earth's atmosphere and many other characteristics. Daily results are presented here on
On Aug. 10, 2017, the network reported 38 fireballs.
(24 sporadics, 12 Perseids, 1 Southern delta Aquariid, 1 alpha Capricornid)
In this diagram of the inner solar system, all of the fireball orbits intersect at a single point--Earth. The orbits are color-coded by velocity, from slow (red) to fast (blue). [Larger image] [movies]
Near Earth Asteroids
Potentially Hazardous Asteroids (PHAs) are space rocks larger than approximately 100m that can come closer to Earth than 0.05 AU. None of the known PHAs is on a collision course with our planet, although astronomers are finding new ones all the time.
On August 10, 2017 there were 1803 potentially hazardous asteroids.

Cosmic Rays in the Atmosphere

Readers, thank you for your patience while we continue to develop this new section of We've been working to streamline our data reduction, allowing us to post results from balloon flights much more rapidly, and we have developed a new data product, shown here:
This plot displays radiation measurements not only in the stratosphere, but also at aviation altitudes. Dose rates are expessed as multiples of sea level. For instance, we see that boarding a plane that flies at 25,000 feet exposes passengers to dose rates ~10x higher than sea level. At 40,000 feet, the multiplier is closer to 50x. These measurements are made by our usual cosmic ray payload as it passes through aviation altitudes en route to the stratosphere over California.
What is this all about? Approximately once a week, and the students of Earth to Sky Calculus fly space weather balloons to the stratosphere over California. These balloons are equipped with radiation sensors that detect cosmic rays, a surprisingly "down to Earth" form of space weather. Cosmic rays can seed clouds, trigger lightning, and penetrate commercial airplanes. Furthermore, there are studies ( #1, #2, #3, #4) linking cosmic rays with cardiac arrhythmias and sudden cardiac death in the general population. Our latest measurements show that cosmic rays are intensifying, with an increase of more than 13% since 2015:
Why are cosmic rays intensifying? The main reason is the sun. Solar storm clouds such as coronal mass ejections (CMEs) sweep aside cosmic rays when they pass by Earth. During Solar Maximum, CMEs are abundant and cosmic rays are held at bay. Now, however, the solar cycle is swinging toward Solar Minimum, allowing cosmic rays to return. Another reason could be the weakening of Earth's magnetic field, which helps protect us from deep-space radiation.
The radiation sensors onboard our helium balloons detect X-rays and gamma-rays in the energy range 10 keV to 20 MeV. These energies span the range of medical X-ray machines and airport security scanners.
The data points in the graph above correspond to the peak of the Reneger-Pfotzer maximum, which lies about 67,000 feet above central California. When cosmic rays crash into Earth's atmosphere, they produce a spray of secondary particles that is most intense at the entrance to the stratosphere. Physicists Eric Reneger and Georg Pfotzer discovered the maximum using balloons in the 1930s and it is what we are measuring today.
