A G1 (Minor) Geomagnetic Storm Watch is in effect for the 29 October, 2022 UTC-day due to anticipated coronal hole high speed stream influences. An approaching co-rotating interaction region ahead of the first of three positive polarity coronal hole high speed streams (CH HSS) is anticipated to enhance and disturb the solar wind environment and lead to unsettled conditions, with a chance for active levels and slight chance of G1 storms as early as 27 October. CH HSS onset and enhanced influences on 28 October are expected to cause unsettled to active levels, with an increased chance of G1 storms. Another CH HSS is expected to begin influencing the solar wind field with additional enhancements on 29 October, leading to unsettled to active conditions, with likely periods of G1 storm levels. While the forecast for 30 October through 2 November is still being worked, it is anticipated that CH HSS influences will keep the solar wind field disturbed and enhanced throughout this period. Please continue to follow the nation's official source of space weather forecasts, warnings, and alerts at our website. Additionally, this will be a great period of time to check out our experimental Auroral Users' Dashboard and provide feedback.
