![]() ![]() 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 greeting card showing the heavy-duty ceramic cup in flight and telling the story of its journey to the stratosphere and back again.Īll sales support hands-on STEM education The students are selling Spock cups to support their cosmic ray ballooning program. The students of Earth to Sky Calculus flew this cup to the stratosphere onboard a cosmic ray research balloon: of brew, and comes from the edge of space. You can now give dad the gift of coffee in a Mr. SPOCK COFFEE CUP: Father's Day is coming. That's too dim to see with the unaided eye, but, as Murtagh's photo shows, it is an easy target for backyard telescopes even in urban areas. The expanding fireball has since brightened 40-fold to magnitude +11. A shock wave escaped the dying star on May 19th (Earth time), creating a 15th magnitude fireball first noticed by Koichi Itagaki of Yamagata, Japan. SN 2023ixf is a Type II supernova caused by the core collapse of a massive star. "I had great views of the supernova through my EVscope Equinox 2," he says. "The supernova was easily visible in my telescope despite the bright lights of the city," reports Terence Murtagh. Turns out, that's bright enough to see from downtown London. Solar flare alerts: SMS TextĪ SUPERNOVA IN LONDON: A week after it exploded in a spiral arm of the Pinwheel Galaxy (M101), new supernova SN 2023ixf has finally peaked in brightness at magnitude +11. Studying the fine structure of sunspot cores may help predict when they will flare-a key goal of space weather forecasting. It is currently the largest solar telescope in the world with a unique ability to photograph the sun in unprecedented detail. Inouye Solar Telescope is a four-meter solar telescope on the island of Maui, Hawai’i. The same kind of motions can be seen in a pan of water boiling on a hot stove. Researchers believe they are turbulent convection cells, which dredge up heat from ~1000 km below. These are known as " umbral dots"-incandescent balls of plasma rising and falling in the otherwise dark heart of the sunspot. They show bright dots speckling the core of sunspot AR3053: In a May 19th press release, the National Science Foundation released new high-resolution images from the Daniel K. IN THE DARK HEART OF A SUNSPOT: Sunspots may not be as dark as we thought. At most, minor G1-class geomagnetic storms could result from the close encounter. ![]() It was hurled into space four days ago by an M1.9-class flare from sunspot complex AR3311-12. G LANCING-BLOW CME POSSIBLE TODAY: NOAA forecasters say that a CME might pass near Earth (or maybe deliver a glancing blow) today, May 26th. 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 AR3311 has a 'beta-gamma' magnetic field that harbors energy for M-class solar flares. ![]()
