Northern lights may be visible from several US states Friday and Saturday as giant hole opens up in sun's atmosphere

A large hole opened up in the sun's atmosphere this week, spewing high-speed solar winds that will paint northern lights displays across several U.S. states this weekend.

#SpaceWeather : #Sun ☀️ activity jumped to moderate over the past day, with 24 total flares. Three of them were M, or moderate flares, and one was edging up toward being an X flare

Forecast:

📆 April 4 we might get more G1-G2 (minor-moderate) #geomagnetic storms
📆 April 5 possibly with more G1 enhancements
📆 April 6 unsettled-to-active conditions as effects from the solar wind stream and #CME start to subside

Unlike the easily predictable #radiation ☢️ exposures from flying through the Van Allen Belts or basking in the background flux of #galactic 🌌 cosmic rays, the dose an #astronaut gets from #solar ☀️ activity can vary enormously. Predicting #SpaceWeather remains a decidedly inexact 🔮 #science. High-energy #protons and #ions can tear through metal and flesh alike, damaging #DNA and other delicate cellular machinery. Typically, these showers are linked to #CME https://www.scientificamerican.com/article/space-weather-could-threaten-nasas-artemis-ii-astronauts-during-their-trip/

#SpaceWeather : The chance for strong flares ☀️ increased to 20%. The main driver is active region #AR4405

Forecast:

📆 April 1: A #CME may provoke enhancements up to G2 (moderate) geomagnetic storming late today

📆 April 2: G1 (minor) #geomagnetic storm levels expected

📆 April 3: Unsettled to active conditions may occur. A chance of G1 (minor) storm intervals exists if the next coronal hole’s fast solar wind stream arrives earlier than expected
