![]() Total eclipses make deep black shadows, in this case blacking out more than 70 miles of terrain. 21, 2017, looked like from the stratosphere over the Nebraska-Wyoming border: Note: We have photographed the shadow of an eclipse before. Just make a note in the COMMENTS BOX of your shopping cart: "Fly my pendant again!" Floating at an altitude 105,000 feet above Earth’s surface, it made contact with space, experiencing temperatures as low as -63 C.īuy the pendent now and for no additional charge we will fly it back to the stratosphere during the annular eclipse. The students launched this pendant on July 17th. You can support the flight by buying a Solar Eclipse Pendant: 14th, they'll launch a cosmic ray research balloon equipped with cameras to photograph the shadow zone of an eclipse over Nevada. SOLAR ECLIPSE PENDANT: The students of Earth to Sky Calculus are about to try something never done before-to photograph the shadow of an annular solar eclipse from the stratosphere. What will emerge from the glare next week? Stay tuned! At that time it will experience maximum solar heat, both evaporating and brightening furiously as it executes a hairpin turn around the sun. The comet may not be visible at all tomorrow morning as it rises above the Catalina Mountains 15 minutes later at 535AM in very bright twilight."Ĭomet Nishimura will make a 0.22 AU close approach to the sun on Sept. 11th at 1220UT (520AM) in bright orange twilight skies," says Olason. "The comet appeared above the Catalina Mountains on Sept. This morning, when Mike Olason of Tucson, Arizona, tried to photograph the comet, he could barely see it through the glare: ![]() Solar flare alerts: SMS TextĬOMET NISHIMURA IS NEARING THE SUN: Sundiving Comet Nishimura (C/2023 P1) is now deep inside the orbit of Mercury. However, a new NASA model shows that the CME will miss Earth. At first it appeared to be on the edge of the Earth-strike zone, set to land a glancing blow later this week. SOHO coronagraphs observed a fast-moving CME emerging from the blast site. 11th (0128 UT), producing an M1.3-class solar flare and a surge of plasma over the sun's northeastern limb: THIS ERUPTION WON'T HIT EARTH: New sunspot AR3429 erupted this morning, Sept. 28, 2023, as a show of thanks for years of service and hope for future daisies: Until then, we will maintain AIM's iconic "daily daisy," frozen at Feb. There may be some hope of a recovery as AIM's orbit precesses into full sunlight in 2024. As a result AIM is offline, perhaps permanently. What happened to NASA's AIM spacecraft, which has been monitoring NLCs since 2007? Earlier this year, the spacecraft's battery failed. As the season progresses, these dots will multiply in number and shift in hue from blue to red as the brightness of the clouds intensifies. For the rest of the season, daily maps from NOAA 21 will be presented here:Įach dot is a detected cloud. ![]() ![]() An instrument onboard NOAA 21 ( OMPS LP) is able to detect NLCs (also known as "polar mesospheric clouds" or PMCs). The first clouds were detected inside the Arctic Circle by the NOAA 21 satellite. The northern season for NLCs began on May 26th. There are no significant equatorial coronal holes on the Earthside of the sun. Switch to: Europe, USA, New Zealand, Antarctica ![]() 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 AR3423 has a 'beta-gamma' magnetic field that harbors energy for Earth-directed M-class solar flares. ![]()
