Previous eruptions in July and October caused the comet to sprout horns-but not this time. THE COMET REPORT: Ice volcanoes on Comet 12P/Pons-Brooks erupted again this week, brightening the comet 100-fold. Fainter photographic auroras (best seen using cameras) may cross the US-Canadian border, dipping into states from New York to Washington. During such storms, naked-eye auroras typically fill the Arctic Circle. NOAA forecasters say that G1-class geomagnetic storms are possible when the CME arrives on Nov. 16th, hurling a CME almost directly toward Earth:

GEOMAGNETIC STORM WATCH (G1): A magnetic filament on the sun erupted yesterday, Nov. 2023 is not a great year for Leonid meteors. This is a far cry from the Leonid meteor storms of 19-2002 when hundreds to thousands of meteors appeared. Peak rates of 10 to 15 meteors/hour are expected overnight from Nov. LEONID METEOR SHOWER THIS WEEKEND: Earth is entering a stream of debris from Comet 55/Tempel-Tuttle, source of the annual Leonid meteor shower. 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. 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.

These two sunspots are stable and quiet, posing no threat for strong solar flares.
