![]() The impact sparked a severe geomagnetic storm with auroras so bright they could be seen as far south as Texas. Each bar comes with a greeting card showing the soap in flight and telling the story of its journey to the stratosphere and back again.Īll sales support hands-on STEM educationĪ SUDDEN DECREASE IN COSMIC RADIATION: Last month, on April 23rd, a CME hit Earth's magnetic field. The students of Earth to Sky are selling space soap to support their cosmic ray ballooning program. Not only does the bar smell like the mint gardens of Vulcan, but also each side of the wrapper features hilarious Spock lore. This bar touched space on April 29, 2023, when it hitched a ride onboard an Earth to Sky Calculus cosmic ray balloon: SPOCK SOAP (VULCAN MINT SCENTED): It's the logical way to get clean: Vulcan-mint scented Spock Soap. Reversed polarity sunspots are therefore more likely to explode. According to a 1982 survey by Frances Tang of the Big Bear Solar Observatory, reversed polarity sunspots are more than twice as likely to develop complex magnetic fields, in which + and – are mixed together. ![]() In one important way, however, they are different. They have the same lifespan and size as ordinary sunspots. In most ways, reversed polarity sunspots are totally normal. Studies show that about 3% of all sunspots violate Hale’s Law. However, AR3296 is the opposite its polarity is reversed. That’s negative on the left, positive on the right. This magnetogram from NASA's Solar Dynamics explains the situation:Īccording to Hale's Law, Solar Cycle 25 sunspots in the sun’s northern hemisphere should have a -/+ polarity. The sunspot's magnetic field is flipped compared to other nearby sunspots in the sun's northern hemisphere. REVERSED POLARITY SUNSPOT: New sunspot AR3296 is breaking the law. Glare from a nearly full Moon will reduce visibility, but this could be offset by an extra dose of meteoroids nudged toward Earth by the gravity of Jupiter. Peak rates of 10 to 30 meteors per hour are expected on the night of May 6-7. METEORS FROM HALLEY'S COMET: Earth is entering a stream of debris from Halley's Comet, source of the annual eta Aquariid meteor shower. 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. Sunspot AR3293 has a 'delta-class' magnetic field that harbors energy for strong M-class solar flares.
