Time to call a Congressional hearing? See for yourself: A point-like object emerged from the glare of the sun, quickly reversed course, then headed back from where it came. 21st weren't sure what they had just seen. It will not hit Earth.Ī WEIRD COMET JUST BUZZEDTHE SUN: Citizen scientists watching SOHO's coronagraph feed on Aug. Indeed, SOHO coronagraphs have detected a bright CME emerging from the blast site. Update: This was a long duration flare that had plenty of time to lift a CME out of the sun's atmosphere. The sun's rotation will turn the blast site toward us in a few days. Neither NASA's Perseverance Mars rover (which has a direct view of the area) nor helioseismic echoes of the sun's farside indicate a sunspot at that location-so it's a bit of a mystery. The source of the flare is hidden behind the sun's eastern limb, so we can't see it from Earth. Here is the spray of debris flying up from the blast site: 26th (2250 UT), but we're not sure what caused it. 'M' IS FOR MYSTERY (UPDATED): Earth-orbiting satelites detected an M1-class solar flare on Aug. 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 AR3415 has a 'beta-delta' magnetic field that harbors energy for M-class solar flares.
