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/
Space weather could threaten NASA’s Artemis II astronauts during their trip to the moon

A major solar storm during the Artemis II mission could harm astronauts. Here’s how NASA is protecting them

Scientific American

#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

ASWFC PRELIMINARY HF RADIO COMMUNICATIONS WARNING 26/30 ISSUED AT 0049UT/31 MARCH 2026 BY THE AUSTRALIAN SPACE WEATHER FORECASTING CENTRE.

A Coronal Mass Ejection has been observed, and is expected to impact Earth at 31/1600UT +/- 10 hours. Maximum Usable Frequencies are expected to become depressed over the following 72 hours.

DEGRADED HF PROPAGATION CONDITIONS EXPECTED FROM 31 MARCH 2026 TO 02 APRIL 2026
