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.
There is no better way to make a sunspot flare than headlining a news item "Failure to Flare." Solar flare alerts: SMS Text. If so, the apparent magnetic complexity of AR3112-i.e., the quality that makes it dangerous-may be a sham. Is this the calm before the storm? Another possibility exists: NOAA analysts suggest that AR3112 could be 2 or 3 separate sunspots traveling together, masquerading as a single behemoth. The giant sunspot has been strangely quiet since it rotated over the sun's eastern limb last week.
7th by Apollo Lasky of Naperville, Illinois It possesses all the ingredients for a big solar storm. The briefing will be broadcast live on NASA TV.įAILURE TO FLARE: Sunspot AR3112 is big, it is magnetically complex, and it is directly facing Earth.

How much damage did DART do? And was the asteroid's trajectory altered? NASA will answer these questions during a mission update on Tuesday, 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.ĭART MISSION UPDATE: Last month, NASA's DART spacecraft deliberately collided with asteroid moon Dimorphos. Credit: SDO/HMIĬosmic Rays Solar Cycle 25 is beginning, and this is reflected in the number of cosmic rays entering Earth's atmosphere. Sunspot AR3112 is strangely quiet despite having a delta-class magnetic field that seemingly harbors energy for strong solar flares.
