According to a study from the Harvard T.H. They can alter the chemistry of the atmosphere, trigger lightning, and penetrate commercial airplanes. Who cares? Cosmic rays are a surprisingly "down to Earth" form of space weather. 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. 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 cup in flight and telling the story of its trip to the stratosphere and back again.Īll sales support hands-on STEM education It's Peanuts for a cup from space! The students are selling Snoopy cups to support their cosmic ray monitoring program. Here is astronaut Snoopy floating more than 105,315 feet above Earth's surface: On July 16th, the students of Earth to Sky Calculus launched everyone's favorite Beagle onboard a cosmic ray research balloon. "It might be the last time this year we see the two together," says Kranich.Ī BEAGLE AT THE EDGE OF SPACE: Snoopy has been to the stratosphere. NLCs fade near the end of summer, while auroras regain visibility vs. "Soon after, I also discovered noctilucent clouds (NLCs) very close to the horizon."Īt Arctic latitudes, this mixture can only be observed at the boundary between seasons. "I saw some green auroras in the ongoing midnight twilight," says Kranich.
Laura Kranich photographed the transition on Aug. Northern summer is coming to an end as autumn approaches. Solar flare alerts: SMS TextĪURORAS AND NOCTILUCENT CLOUDS: Seasons are changing. We'll keep an eye on AR3088 to see what happens next. What's going on? Something unusual may be happening to the sun's magnetic dynamo beneath the surface where this sunspot is growing. This is a rare "perpendicular sunspot," with magnetic poles orthogonal to the sun's equator. Instead, they are rotated 90 degrees positive (+) is on top and negative (-) is on the bottom. According to Hale's Law, the sunspot's magnetic poles should be arranged +/-, that is, positive (+) on the left and negative (-) on the right. Shown above is a map of magnetic fields on the sun. Stay tuned.Ī STRANGELY MAGNETIZED SUNSPOT: New sunspot AR3088 is emerging in the sun's southern hemisphere. Satellite observers are keenly interested to see how it looks in the night sky. Designed to supply 4G cell phone signals from space, Bluewalker 3 will unfurl a large, bright antenna spanning 64 square meters. 7th, SpaceX will launch an unusual satellite: BlueWalker 3. 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.

On their road to becoming accepted, they encounter many hilarious obstacles, which gives the movie an overall sense of silliness.AR3088 is a "perpendicular sunspot." It's magnetic field is rotated 90 degrees compared o other sunspots. Their living and breathing creation is a gorgeous woman, Lisa, whose purpose is to boost their confidence level by putting them into situations which require Gary and Wyatt to act like men. Their desperation to be liked leads them to "create" a woman via their computer. Two unpopular teenagers, Gary Wallace and Wyatt Donnelly, fail at all attempts to be accepted by their peers.
