The greater than 10 MeV proton flux remained at background levels during this period.<\/p>\n<p>The greater than 2 MeV electron flux is forecasted to be at moderate to high levels on December 9 and 10, influenced by the coronal hole high-speed stream (CH HSS). On December 11, moderate electron flux levels are expected. The greater than 10 MeV proton flux is anticipated to persist at background levels from December 9 through 11.<\/p>\n<p>Solar wind parameters continued to decline over the period. The solar wind speed decreased from about 485 km\/s to nearly 425 km\/s. The total field ranged from 1 to 4 nT, with the Bz component oscillating between +\/-3 nT. The Phi angle was predominantly negative.<\/p>\n<p>Solar wind parameters are expected to remain at or near nominal levels on December 9 and 10. A weak enhancement is likely on December 11, attributed to the onset of a positive polarity CH HSS.<\/p>\n<p>The geomagnetic field was quiet and is expected to remain mostly quiet on December 9 and 10. On December 11, quiet to unsettled levels are expected, likely due to CH HSS activity.<\/p>\n<p>References:<\/p>\n<p><sup>1<\/sup> Forecast Discussion \u2013 Issued: 2023 Dec 09 0030 UTC \u2013 Prepared by the U.S. Dept. of Commerce, NOAA, Space Weather Prediction Center<\/p>\n<p class=\"has-theme-palette-6-color has-text-color has-link-color wp-elements-29935f230babc2a8fb9b7ce8f80522a5\"><em>Featured image credit: NASA AIA\/131, The Watchers<\/em><\/p>\n<p><center><\/p>\n<p>If you value what we do here, create your ad-free account and support our journalism.<\/p>\n<p><\/center>\n<link rel=\"stylesheet\" id=\"kadence-blocks-tabs-css\" data-pmdelayedstyle=\"https:\/\/watchers.news\/wp-content\/plugins\/kadence-blocks\/dist\/style-blocks-tabs.css?ver=3.1.26\" media=\"all\"\/>\n<!-- [element-170997] --><\/p>\n<div class=\"ultp-shortcode\" data-postid=\"170999\">\n<div class=\"wp-block-kadence-tabs alignnone\">\n<div class=\"kt-tabs-wrap kt-tabs-id_d8b568-69 kt-tabs-has-3-tabs kt-active-tab-1 kt-tabs-layout-tabs kt-tabs-tablet-layout-accordion kt-tabs-mobile-layout-accordion kt-tab-alignment-center kt-create-accordion\" style=\"max-width:none\">\n<div class=\"kt-tabs-content-wrap\">\n<div class=\"wp-block-kadence-tab kt-tab-inner-content kt-inner-tab-1 kt-inner-tab_bb21d2-0d\">\n<div class=\"kt-tab-inner-content-inner\">\n<div class=\"wp-block-ultimate-post-post-list-3 ultp-block-beba19\">\n<div class=\"ultp-block-wrapper\">\n<div class=\"ultp-block-items-wrap ultp-block-row ultp-block-column-1 ultp-block-content-middle ultp-layout1\">\n<section class=\"ultp-block-item ultp-block-media post-id-178390\">\n<div class=\"ultp-block-content-wrap\">\n<div class=\"ultp-block-content\">\n<h3 class=\"ultp-block-title \">Multiple CMEs heading toward Earth, G3 \u2013 Strong Geomagnetic Storm Watch in effect<\/h3>\n<p><span class=\"ultp-block-date\">Wednesday, November 29, 2023<\/span><\/p>\n<\/div>\n<\/div>\n<\/section>\n<section class=\"ultp-block-item ultp-block-media post-id-178306\">\n<div class=\"ultp-block-content-wrap\">\n<div class=\"ultp-block-content\">\n<h3 class=\"ultp-block-title \">M9.8 solar flare erupts from geoeffective Region 3500, Earth-directed CME likely<\/h3>\n<p><span class=\"ultp-block-date\">Tuesday, November 28, 2023<\/span><\/p>\n<\/div>\n<\/div>\n<\/section>\n<section class=\"ultp-block-item ultp-block-media post-id-177509\">\n<div class=\"ultp-block-content-wrap\">\n<div class=\"ultp-block-content\">\n<h3 class=\"ultp-block-title \">Large filament eruption produces partial-halo CME, impact to Earth expected on November 5<\/h3>\n<p><span class=\"ultp-block-date\">Saturday, November 4, 2023<\/span><\/p>\n<\/div>\n<\/div>\n<\/section>\n<section class=\"ultp-block-item ultp-block-media post-id-176288\">\n<div class=\"ultp-block-content-wrap\">\n<div class=\"ultp-block-content\">\n<h3 class=\"ultp-block-title \">Strong M8.7 solar flare erupts from Region 3435<\/h3>\n<p><span class=\"ultp-block-date\">Thursday, September 21, 2023<\/span><\/p>\n<\/div>\n<\/div>\n<\/section>\n<section class=\"ultp-block-item ultp-block-media post-id-176253\">\n<div class=\"ultp-block-content-wrap\">\n<div class=\"ultp-block-content\">\n<h3 class=\"ultp-block-title \">Strong M8.2 solar flare erupts from Region 3435<\/h3>\n<p><span class=\"ultp-block-date\">Wednesday, September 20, 2023<\/span><\/p>\n<\/div>\n<\/div>\n<\/section>\n<section class=\"ultp-block-item ultp-block-media post-id-176138\">\n<div class=\"ultp-block-content-wrap\">\n<div class=\"ultp-block-content\">\n<h3 class=\"ultp-block-title \">G2 \u2013 Moderate to G3 \u2013 Strong geomagnetic storm conditions forecast for September 19<\/h3>\n<p><span class=\"ultp-block-date\">Monday, September 18, 2023<\/span><\/p>\n<\/div>\n<\/div>\n<\/section>\n<section class=\"ultp-block-item ultp-block-media post-id-175267\">\n<div class=\"ultp-block-content-wrap\">\n<div class=\"ultp-block-content\">\n<h3 class=\"ultp-block-title \">Major X1.5 solar flare erupts from Region 3386<\/h3>\n<p><span class=\"ultp-block-date\">Monday, August 7, 2023<\/span><\/p>\n<\/div>\n<\/div>\n<\/section>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<p><!-- [\/element-170997] --><\/div>\n<p><br \/>\n<br \/><a href=\"https:\/\/watchers.news\/2023\/12\/09\/impulsive-m5-4-solar-flare-erupts-from-region-3511-multiple-filament-eruptions\/?rand=772108\">Source link <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>An impulsive solar flare measuring M5.4 erupted from Active Region 3511 at 23:07 UTC on December 8, 2023.
