The emergence of multiple new sunspots on the solar disk plus a new farside sunspot rotating over the sun's eastern limb is driving the sunspot number back up to 100. SUNSPOT NUMBERS ARE BOUNCING BACK: After a two week decline, which reminded some observers of Solar Minimum, sunspot numbers are bouncing back. 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. Switch to: Europe, USA, New Zealand, AntarcticaĪ new coronal hole is emerging over the sun's southeastern limb. 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 AR3474 has a 'beta-gamma' magnetic field that harbors energy for M-class solar flares.
