On Monday, Sept. 26th, the giant planet will be just 591 million kilometers away. Yes, that really is close. Look for Jupiter rising in the east at sunset shining four times brighter than Sirius, the brightest star in the sky. Through a backyard telescope it looks like this. SPACEX JELLYFISH: Up and down the US east coast, people are reporting a comet-like object in the sunset sky. "I saw it from the riverfront in Wilmington, North Carolina," says Conrad Pope, who had to combine four side-by-side exposures to capture the entire phenomenon: 
It was a SpaceX Jellyfish, created by the Saturday evening (7:32 pm EDT) launch of a Falcon 9 rocket from Cape Canaveral. Fifty-two new Starlink satellites were onboard. These formations appear almost every time SpaceX launches a new batch of Starlinks at dusk or dawn. Sunlight reaches up from below the horizon to illuminate the exhaust plume, making it extremely visible in the twilight sky. more images: from Dr. Gilbert Plumer of Rockledge, Florida; from Kevin R Witman of Georgetown, Maryland; from Alessandro Magli of Belmont, Massachusetts; from Brent of Orlando, Florida Realtime Starlink Photo Gallery
Free: Spaceweather.com Newsletter A GIANT PROMINENCE AND THE ISS: For days, solar astronomers have been monitoring a behemoth prominence on the sun's southeastern limb. Eduardo Schaberger Poupeau was watching yesterday when the International Space Station (ISS) flew by: 
"The huge prominence rising 100,000 km above the sun's surface was already a great spectacle," says Poupeau. "The addition of the ISS made it a special view indeed." The ISS is gone now, and so is the prominence. It erupted during the late hours of Sept. 24th. SOHO coronagraphs show a CME emerging from the blast site. The storm cloud will not hit Earth.

Free: Spaceweather.com Newsletter 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 Sep 24, 2022, the network reported 27 fireballs.
(27 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 September 25, 2022 there were 2294 potentially hazardous asteroids.

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. | | The official U.S. government space weather bureau | | | The first place to look for information about sundogs, pillars, rainbows and related phenomena. | | | Researchers call it a "Hubble for the sun."
