New sunspot AR3372 is seething with activity.

The CME was hurled into space on July 11th by an erupting magnetic filament in the sun's southern hemisphere. The glancing blow could spark minor G1-class geomagnetic storms with high-latitude auroras. NOAA and NASA analysts agree: A CME will hit Earth's magnetic field on July 14th or 15th. 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.

New sunspot AR3372 poses a threat for strong M-class solar flares.
