The greater than 10 MeV proton flux remained at background levels during the same period.<\/p>\n<p>The 2 MeV electron flux is expected to remain elevated through February 4 as the positive polarity coronal hole high-speed stream (CH HSS) influence persists, though gradually diminishing. There is a slight chance for greater than 10 MeV proton levels to reach S1 \u2013 Minor storm levels between February 3 and 5.<\/p>\n<p>The solar wind environment continued under the influence of a positive polarity CH HSS in 24 hours to 00:30 UTC today. The total magnetic field strength averaged near 5 nT before increasing slightly to peak at 11 nT at 17:35 UTC on February 2. The Bz component varied between +\/-6 nT until around 16:00 UTC when it rotated mostly north.<\/p>\n<p>Solar wind speeds, as measured by the ACE spacecraft, began just under 700 km\/s and gradually declined to just over 500 km\/s by the end of the period. The phi angle remained predominantly in the positive sector until around 16:00 UTC, when it shifted to a negative orientation.<\/p>\n<p>Enhancements in solar wind parameters are expected to continue through February 3 and 4 due to the persistent yet weakening positive polarity CH HSS influence, along with the possible interaction of the January 31 CME on February 4. By February 5, solar wind parameters are expected to return to near-background levels as CH HSS and CME influences subside.<\/p>\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"865\" alt=\"rtsw 3 days to february 3 2025\" class=\"wp-image-215629 perfmatters-lazy\" src=\"https:\/\/watchers.news\/wp-content\/uploads\/2025\/02\/rtsw-3-days-to-february-3-2025-1024x865.webp\" srcset=\"https:\/\/watchers.news\/wp-content\/uploads\/2025\/02\/rtsw-3-days-to-february-3-2025-1024x865.webp 1024w, https:\/\/watchers.news\/wp-content\/uploads\/2025\/02\/rtsw-3-days-to-february-3-2025-300x253.webp 300w, https:\/\/watchers.news\/wp-content\/uploads\/2025\/02\/rtsw-3-days-to-february-3-2025-768x649.webp 768w, https:\/\/watchers.news\/wp-content\/uploads\/2025\/02\/rtsw-3-days-to-february-3-2025.webp 1158w\" data-sizes=\"(max-width: 1024px) 100vw, 1024px\"\/><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"865\" src=\"https:\/\/watchers.news\/wp-content\/uploads\/2025\/02\/rtsw-3-days-to-february-3-2025-1024x865.webp\" alt=\"rtsw 3 days to february 3 2025\" class=\"wp-image-215629\" srcset=\"https:\/\/watchers.news\/wp-content\/uploads\/2025\/02\/rtsw-3-days-to-february-3-2025-1024x865.webp 1024w, https:\/\/watchers.news\/wp-content\/uploads\/2025\/02\/rtsw-3-days-to-february-3-2025-300x253.webp 300w, https:\/\/watchers.news\/wp-content\/uploads\/2025\/02\/rtsw-3-days-to-february-3-2025-768x649.webp 768w, https:\/\/watchers.news\/wp-content\/uploads\/2025\/02\/rtsw-3-days-to-february-3-2025.webp 1158w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\"\/><figcaption class=\"wp-element-caption\">Image credit: SWPC<\/figcaption><\/figure>\n<\/div>\n<p>The geomagnetic field remained at quiet to active levels due to the ongoing influence of the positive polarity CH HSS.<\/p>\n<p>Active geomagnetic conditions are likely early on February 3, with a slight chance of isolated G1 \u2013 Minor storm conditions as the CH HSS influence continues.<\/p>\n<p>Further active conditions may develop late on February 4 if the January 31 CME interacts with Earth\u2019s magnetosphere.
