THIS ASTEROID IS HEADING FOR BETELGEUSE: Astronomers are excited. Minor G1-class geomagnetic storms are possible when the CME arrives. Updated forecast models suggest that a CME flung into space by the filament could graze Earth's magnetic field on Nov. 22 0600 UT), carving a deep ' canyon of fire' in the sun's atmosphere. SPECTACULAR 'CANYON OF FIRE' ERUPTION (UPDATED-AGAIN): A dark filament of magnetism erupted from the sun yesterday (Nov. 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 coronal holes on the Earthside of the sun.

Sunspot complex AR poses a continued threat for M-class solar flares.
