Proton flux started rapidly rising at 07:30 UTC on February 12, 2024, following what appears to be an eruption from the old Region 3575 – now traversing the farside of the Sun.
A newly-discovered asteroid designated 2024 CY1 flew past Earth at 07:24 UTC on February 12, 2024, at a distance of 0.31 LD / 0.00081 AU (121 148 km / 75 278 miles).
A moderately strong M6.5 solar flare erupted from Active Region 3576 at 03:48 UTC on February 12, 2024. The event started at 03:23 and ended at 03:53 UTC.
Forecasters at the National Weather Service (NWS) issued a warning on February 11, 2024, about a significant winter storm impacting the Southern Rockies and High Plains, moving northeast towards the Northern Mid-Atlantic, New York, and New England. Expected heavy snowfall, powerful winds, and potential coastal flooding are set to disrupt travel and cause power outages across affected regions.
A strong solar flare measuring M9.0 erupted at 23:07 UTC on February 10, 2024 from geoeffective Active Region 3576. The event started at 22:56 and ended at 23:14 UTC.
A strong earthquake registered by the USGS as M5.7 (downgraded from M6.3) hit the southeastern flank of Mauna Loa volcano in Hawaii at 20:33 UTC on February 9, 2024. The agency is reporting a depth of 36.8 km (22.8 miles).
Data released by the Icelandic Met Office (IMO) shows that about 15 million cubic meters (530 million cubic feet) of lava flowed in the first seven hours of the eruption near Grindavik on February 8, 2024. The eruption has since decreased significantly but is still not over.
A powerful solar flare measuring X3.3 erupted behind the SW limb of the Sun (AR 3575) at 13:14 UTC on February 9, 2024. This solar flare is the second most intense in Solar Cycle 25, following an X5.0 flare that occurred on January 31, 2023.
Researchers from Penn State and Brown University have uncovered how rocks from ancient subduction zones can forecast tectonic behaviors between significant earthquakes, enhancing our ability to predict such natural disasters.
A strong and shallow earthquake registered by the USGS as M6.1 hit Kermadec Islands, New Zealand at 10:57 UTC on February 9, 2024. The agency is reporting a depth of 10 km (6.2 miles).
