The sun's strengthening and increasingly tangled magnetic field repels cosmic rays from deep space. Solar Cycle 25 has roared to life faster than forecasters expected. What's going on? Ironically, the radiation drop is caused by increasing solar activity. Our latest measurements in July 2022 registered a 6-year low: Latest results (July 2022): Atmospheric radiation is decreasing in 2022. Our monitoring program has been underway without interruption for 7 years, resulting in a unique dataset of in situ atmospheric measurements. 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. SPACE WEATHER BALLOON DATA: Almost once a week, and the students of Earth to Sky Calculus fly space weather balloons to the stratosphere over California. 'Lunar Distance.' 1 LD = 384,401 km, the distanceīetween Earth and the Moon. Each one comes with a greeting card showing the bird and red lily in flight, and telling the story of their trip to the stratosphere and back again.Īll sales support hands-on STEM education The students are selling hummingbird pendants to pay the helium bill for their cosmic ray ballooning program. 22, 2022, the students of Earth to Sky Calculus launched the sterling silver pendant to the stratosphere onboard a cosmic ray research balloon, more than 117,710 feet high: STERLING SILVER HUMMINGBIRD PENDANT: This hummingbird has touched space. More images: from Andrea Aletti of Campo dei Fiori Mount, Italy How much is left? Was its trajectory altered? The broadcast will be streamed live starting at 2pm EDT on NASA TV. 11th, NASA will hold a media briefing to reveal what happened to Dimorphos. Little Dimorphos is only 170 meters across, but its tail stretches 10,000 kilometers into space. This happened via the same process that gives comets their tails: Radiation from the sun pushes material into a stream behind the main body of the object. Much of that cloud has since stretched into a tail behind the asteroid. Images taken immediately after the collision showed a huge cloud of dust surrounding Dimorphos. 'Almost two weeks after impact, the dust trail is still visible-amazing!' 'This is a 14x180 second exposure captured using the iTelescope T72 in Chile,' says Herman. Amateur astronomer Eliot Herman photographed the tail of Dimorphos on Oct. THE TAIL OF ASTEROID DIMORPHOS: Last month when NASA slammed the DART spacecraft into asteroid Dimorphos, something unexpected happened. Confirmation awaits fresh data from SOHO coronagraphs. The explosion lasted more than 3 hours, plenty of time to lift a CME out of the sun's atmosphere. Aviators, mariners and ham radio operators may have noticed fading and other unusual effects at frequncies below 15 MHz.

Radiation ionized the top of Earth's atmosphere, producing a shortwave radio blackout over the South Pacific: map. 10th (0047 UT), producing an M1-class solar flare: LONG DURATION SOLAR FLARE: Underachieving sunspot AR3112 finally exploded on Oct. High-latitude sky watchers should be alert for auroras. 10th, in response to sustained pressure from a high-speed stream of solar wind. GEOMAGNETIC STORM WATCH: NOAA forecasters say there is a chance of minor G1-class geomagnetic storms today, Oct. 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.

Sunspot AR3112 has a delta-class magnetic field that harbors energy for strong solar flares.
