![]() 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 pendant in flight and telling the story of its journey to the stratosphere and back againĪll sales support hands-on STEM education The students of Earth to Sky Calculus are selling space pendants to support their cosmic ray ballooning program. Space Snoopy makes a great birthday, anniversary or Mother's day gift. This sterling silver pendant flew to the stratosphere on April 15, 2023, floating on a cosmic ray balloon 117,400 feet above the Sierra Nevada mountains of central California: SILVER SNOOPY SPACE PENDANT: Snoopy has touched space. Between now and then, we might see some nice farside CMEs in SOHO coronagraph images. The sun's rotation will turn it to face Earth late next week. Sunspots on this scale are usually active. The black blob is a sunspot group-big enough to alter the way the sun vibrates. Their latest map reveals a huge farside active region: However, researchers using a technique called "helioseismology" can make crude maps of the sun's hidden hemisphere. Aurora alerts: SMS Text.īIG FARSIDE SUNSPOT: You might suppose that the farside of the sun is hidden from view. ![]() A bit of a dud, the impact sparked only a minor G1-class geomagnetic storm and no widespread auroras. "DUD" CME IMPACT SPARKS MINOR STORM: A CME hit Earth's magnetic field on May 12th at 0635 UT, deflecting magnetometer needles at the Ottawa Magnetic Observatory by 34 nT. 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. Credit: SDO/HMIĬosmic Rays Solar Cycle 25 is intensifying, and this is reflected in the number of cosmic rays entering Earth's atmosphere. Sunspots AR3296 and AR3297 have 'beta-gamma' magnetic fields that harbor energy for M-class solar flares.
