28, 2023, as a show of thanks for years of service and hope for future daisies:īIRTH OF A NEW METEOR SHOWER? A new preprint by respected meteor forecaster Jeremie Vaubaillon and colleagues urges sky watchers to be alert for a new southern hemisphere meteor shower in Dec. 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.

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.

Nw sunspot AR3513 is rapidly growing and crackling with M-class solar flares.
