Sorry, the CME has failed to produce any excitement for us on Earth. The IMF Bz has remained in positive territory most of the day and Earth seems to have failed to make it into the core magnetic structure of the CME.

If anything changes I'll try to announce it here.

Rocket Launch Livestream for NASA's Artemis II Moon Mission YouTube video by Stefan Burns

On April 1st, 2026, NASA plans to send 4 astronauts on the first manned Moon mission in ~55 years, exploring deeper into space than ever before. This comes just as the Earth-facing side of the Sun is covered with numerous active sunspots, and a sungrazer comet that could provoke them.

Will it be a GO or NO GO for the #ArtemisII mission today? 🚀🌚

#NASA teams are 80% confidence that weather will play nice. But what about the other 20%? @CW39Houston

#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 3: Unsettled to […]

#solarstorm update — the CME-driven shock arrived at Earth at ~11:30 UTC on Apr 1, significantly later than predicted. Likely a flank encounter: L1 solar wind measurements show total magnetic field strength <15 nT with a speed of ~500 km/s, resulting in no significant disturbances 😴 #SpaceWeather

The earlier mentioned coronal hole just to the west of the flare location is restraining the westward extent of the CME. We'll see the fast solar wind from the coronal hole in a couple of days.

Could a solar storm derail the Artemis II mission? Solar particle events are an ever-present risk to space travellers venturing beyond Earth orbit.

An article from my research group about the risks of space weather and radiation for the Artemis missions was released this morning. Do give it a read! #Artemis #SpaceWeather

Late as usual, the CME has arrived at L1. Effects at Earth should be expected in 45-60 minutes. Bz is currently slightly southward.

HF #Propagation Report - We are still expecting a CME to arrive. Geomagnetic activity will remain mostly quiet; upon the CME’s arrival, G1–G2-class storms (Kp 5–6) are possible. Solar activity is currently low, with an increasing risk of flares (M 55% X 20% Proton 20%). #spaceweather #hamradio #hamr

Fireball sightings across the USA and the whole world have increased dramatically since the beginning of March, a month with no known regular meteor stream.

Earth may catch the edge of the one of the "legs" of the CME, which stretch al; the way back to the sun as the CME expands outwards into the solar system.

382E-418-Fireball II Recently there were four fireball meteors, brighter than the planet Venus, which exploded over Germany, France, Ohio, and Arizona within the space of only 10 hours. A total of 1320 individuals were treated to light shows and reported their observations to the American Meteor Society. The one which exploded over Arizona was probably several feet in diameter and entered the Earth's atmosphere over Flagstaff. This event was observed in Arizona, California, Nevada, Utah, New Mexico, and Colorado. It was recorded by numerous electronic security and dashboard cameras and was visible for from 3 to 7 seconds. This meteor also produced a booming sound which was reported by about a dozen different observers. The fireball was last seen over Happy Jack, Arizona and is likely to have produced meteorite fragments which are scattered along Interstate 17 somewhere in the rugged country between Phoenix and Flagstaff. There are likely to be on the order of 1,000 fireball events over the Earth every day. Most of them occur over the oceans or during the day and pass unobserved by humans. During the first 10 months of 2017 the most energetic fireball event occurred when a meteoroid entered the Earth's atmosphere at 8.5 miles/second above the ocean between Australia and Antartica. If you record a fireball with your dash cam or security camera report it to the American Meteor Society. Your data will be very important in finding out where it came from in the solar system as well as to indicate where it might be possible to find pieces of it on the ground.

A G2 geomagnetic storm watch is in effect until 00h UT tonight.

A G1 watch is in effect for 01 and 02 April.

We're expecting a glancing blow from the CME launched by yesterday's X1.5 flare.

The CME launched by this morning's X1.5 flare is likely to give Earth a glancing blow late on 31 March or early 01 April.
