'I took this picture from Svalbard, a group of isles about 1300 km south of the North Pole,' says Spijkers. 1st when she looked up at noon and saw the Northern Lights: Yet that is exactly what happened to Marjan Spijkers on Dec. Aurora alerts: SMS TextĭAYTIME AURORAS OVER 'THE ISLAND OF POLAR BEARS': It's not easy to see auroras in the middle of the day when the sky is suffused with sunlight. A glancing-blow CME may yet provide a light show. High-latitude sky watchers should nevertheless remain alert for auroras on Dec.

This is in response to the weaker-than-expected impact of solar wind flowing from a huge coronal hole. UPDATED GEOMAGNETIC STORM WATCH (G1): NOAA forecasters have downgraded the current geomagnetic storm watch from G2 (Moderate) to G1 (Minor).

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. Solar wind flowing from this large coronal hole should reach Earth on Dec. 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. Departing sunspot AR3500 has a 'beta-gamma' magnetic field that poses a threat for M-class solar flares.
