UNEXPECTED GEOMAGNETIC STORM: This was not in the forecast. An interplanetary shock wave unexpectedly hit Earth's magnetic field on June 7th (11:30 UT), sparking a G2-class geomagnetic storm. The shock wave might have been a previously unrecognized CME, either too faint to see or misclassified as a farside event. The storm, which lasted approximately 6 hours, is over now.

A NOVA WILL EXPLODE THIS SUMMER (PROBABLY): The night sky is about to get a new star. Sometime this summer, astronomers believe, a nova will explode in the constellation Corona Borealis (the Northern Crown). The exploding star will be bright enough to see with the naked eye even from light-polluted cities.

"It’s a once-in-a-lifetime event," says Rebekah Hounsell of NASA’s Goddard Space Flight Center. "I believe it will create a lot of new astronomers out there."
T Coronae Borealis (T CrB) is a binary system 3,000 light-years from Earth. It consists of a white dwarf orbiting an ancient red giant. Hydrogen from the red giant is being pulled down onto the surface of the white dwarf, accumulating toward a critical mass. Eventually, it will trigger a thermonuclear explosion.
The last time T CrB exploded was in 1946. About a year before that blast, the system suddenly dimmed--a pattern astronomers called the "pre-eruption dip." In 2023, T CrB dipped again, heralding a new eruption. If the 1946 pattern repeats itself, the nova should occur between now and September 2024.

The outburst will be brief. Once it erupts, the nova will be visible to the naked eye for a little less than a week – but Hounsell is confident it will be quite a sight to see. The expected magnitude is between +2 and +3, similar to stars in the Big Dipper.
"Typically, nova events are faint and far away," says Elizabeth Hays, chief of the Astroparticle Physics Laboratory at NASA Goddard. "This one will be really close, with a lot of eyes on it. We can’t wait to get the full picture of what's going on."

STERLING SILVER GEOMAGNETIC CAT: On May 10, 2024, a CME slammed into Earth's magnetic field, sparking the biggest geomagnetic storm in 35 years. Moments later, the students of Earth to Sky Calculus launched a cosmic ray balloon directly into the storm. The Geomagnetic Cat Pendant went along for the ride:
This sterling silver feline floated through the stratosphere for 3 hours during the storm, gathering radiation data for the students' monitoring program. Later, when the sun set and the sky grew dark, red and green auroras danced above the Sierra Nevada mountains of California where the balloon was launched.
You can have it for $219.95. The pendant comes with a greeting card showing the cat in flight and telling the story of its journey to the stratosphere and back. This is truly a once-in-a-lifetime gift.

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 Jun 07, 2024, the network reported 5 fireballs.
(5 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). [Larger image] [movies]
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 June 7, 2024 there were 2349 potentially hazardous asteroids.

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 (July 2022): Atmospheric radiation is decreasing in 2022. Our latest measurements in July 2022 registered a 6-year low:
What's going on? Ironically, the radiation drop is caused by increasing solar activity. Solar Cycle 25 has roared to life faster than forecasters expected. The sun's strengthening and increasingly tangled magnetic field repels cosmic rays from deep space. In addition, solar coronal mass ejections (CMEs) sweep aside cosmic rays, causing sharp reductions called "Forbush Decreases." The two effects blend together to bring daily radiation levels down.
.Who cares? Cosmic rays are a surprisingly "down to Earth" form of space weather. They can alter the chemistry of the atmosphere, 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. A number of controversial studies (#1, #2, #3, #4) go even further, linking 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 graph labeled "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.
