4/15/2023 0 Comments Meteoroid gif![]() 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. The 10mm cultured white pearl, surrounded by a crystalline splash of spring-green cubic zirconia, spent more than 2 hours in the stratosphere as sensors in the payload measured cosmic rays.Įach purchase comes with a greeting card showing the pearl in flight and telling the story of its journey to the stratosphere and back again.Īll sales support hands-on STEM education Here it is, floating 111,202 feet above the Sierra Nevada mountains of central California: THE VERNAL EQUINOX PEARL: Are you looking for a far-out gift? Consider the Vernal Equinox Pearl, launched to the edge of space onboard an Earth to Sky Calculus cosmic ray balloon. The sunspot will turn to face Earth this week. It is the likely source of several jets and plumes of hot plasma flying over the sun's southeastern limb during the past 24 hours. Their latest map reveals a farside sunspot: However, researchers using a technique called "helioseismology" can make crude maps of the sun's hidden hemisphere. Solar flare alerts: SMS Text.įARSIDE SUNSPOT : You might suppose that the farside of the sun is hidden from view. Any explosions will be geoeffective as the sunspot is turning to face Earth. Almost certainly, the source would be sunspot AR3272, which has an unstable 'beta-gamma' magnetic field. 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.ĬHANCE OF FLARES TODAY : NOAA forecasters say there is a 30% chance of M-class solar flares today, April 9th. NOTE: Due to a temporary technical malfunction at the source, daily values of TCI are not available this week.Ĭosmic Rays Solar Cycle 25 is intensifying, and this is reflected in the number of cosmic rays entering Earth's atmosphere. Sunspot AR3272 has a 'beta-gamma' magnetic field that poses a threat for M-class solar flares. ![]()
