GLANCING-BLOW CMEs: In recent days, the sun has produced multiple coronal mass ejections (CMEs). None of them is heading directly toward Earth; nevertheless, they might touch our planet. Glancing blows are possible on Jan. 23rd, 24th, and 25th. The impacts, if they occur, are not expected to cause geomagnetic storms but could brighten auroras inside the Arctic Circle. Aurora alerts: SMS Text.
A SUNSET FROM TONGA? When the sun goes down tonight, take a look at the fading sky. If the twilight turns purple, you might have spotted a "Tonga sunset." Heiko Ulbricht photographed this example last night in Großopitz, Germany:
"A strong purple light appeared 26 min after sunset," says Ulbricht. "This could be aerosols from the eruption of the Hunga Tonga-Hunga Ha' apai volcano earlier this month."
Indeed it could. On Jan. 15th, the volcano hurled 400 million kilograms of sulfur dioxide into the upper atmosphere, reaching altitudes never before seen by NASA's fleet of Earth-orbiting satellites. A huge cloud of sulfurous aerosols passed over Australia and has since been spreading around the world through the stratosphere.
Purple sunsets may be a sign that these aerosols have reached you. Volcanic aerosols in the stratosphere scatter blue light which, when mixed with ordinary sunset red, produces a purple hue.
But purple isn't the only thing to look for. In addition, sky watchers should be alert for a bright yellow twilight arch, fine cloud structures in the arch, and long purple rays. These are all potential signs of a "Tonga sunset." If you see one, submit your picture here.

VALENTINE'S SPACE PUP: You've heard of Aphrodite, the Greek goddess of love. Now let us introduce you to Aphrodoggy. This lovable puppy just traveled to the stratosphere onboard an Earth to Sky Calculus cosmic ray research balloon:
You can have it for $109.95. The students are selling plush pups to support their high-altitude ballooning program. Holding a red rose for Valentine's day, each snuggly canine comes with a greeting card showing the 9-inch tall puppy in flight and telling the story of her journey to the stratosphere and back again.

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 Spaceweather.com.
On Jan 22, 2022, the network reported 4 fireballs.
(4 sporadics)
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).

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 January 23, 2022 there were 2255 potentially hazardous asteroids.

Cosmic Rays in the Atmosphere |
SPACE WEATHER BALLOON DATA: Almost once a week, Spaceweather.com and the students of Earth to Sky Calculus fly space weather balloons to the stratosphere over California. These balloons are equipped with sensors that detect secondary cosmic rays, a form of radiation from space that can penetrate all the way down to Earth's surface. Our monitoring program has been underway without interruption for 7 years, resulting in a unique dataset of in situ atmospheric measurements.
Latest results (Nov. 2021): Our balloons have just measured a sudden drop in atmospheric radiation. It happened during the strong geomagnetic storms of Nov. 3-4, 2021. Here are the data:
This is called a "Forbush decrease," named after American physicist Scott Forbush who studied cosmic rays in the early 20th century. It happens when a CME from the sun sweeps past Earth and literally pushes cosmic rays away from our planet. Radiation from deep space that would normally pepper Earth's upper atmosphere is briefly wiped out.
We have measured Forbush decreases before. For example, here's one from Sept. 2014. The Forbush Decrease of Nov. 3-4, 2021, was the deepest in the history of our 7-year atmospheric monitoring program. Radiation levels in the stratosphere over California dropped nearly 20%, more than doubling the previous record from our dataset.
En route to the stratosphere, our sensors also pass through aviation altitudes, so we can sample radiation where planes fly. This plot shows how the Forbush decrease was restricted to the stratosphere; it did not affect lower levels of the atmosphere:
The dose rates shown above are expressed 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. The higher you fly, the more radiation you will absorb.
.Who cares? Cosmic rays are a surprisingly "down to Earth" form of space weather. They can seed clouds, trigger lightning, and penetrate commercial airplanes. According to a study from the Harvard T.H. Chan school of public health, crews of aircraft have higher rates of cancer than the general population. The researchers listed cosmic rays, irregular sleep habits, and chemical contaminants as leading risk factors. Somewhat more controversial studies (#1, #2, #3, #4) link cosmic rays with cardiac arrhythmias and sudden cardiac death.
.Technical notes: 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.
Data points in the first graph ("Stratospheric Radiation") correspond to the peak of the Regener-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 Regener and Georg Pfotzer discovered the maximum using balloons in the 1930s and it is what we are measuring today.
