The Sun emitted a strong solar flare on June 3, peaking at 7:28 a.m. ET. NASA’s Solar Dynamics Observatory captured an image of the event, which was classified as X1.0. https://go.nasa.gov/3Q2vtEJ

Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth’s atmosphere to physically affect humans on the ground. However — when intense enough — they can disturb the atmosphere in the layer where GPS & communications signals travel.

To see how such space weather may affect Earth, check out NOAA NWS Space Weather Prediction Center, the U.S. government’s official source for space weather forecasts, watches, warnings, and alerts.

: Eyewitnesses in Ohio and Michigan reported a bright meteor on Monday, June 1, at 10:41p.m. EDT. The data puts first detection of the fireball above the Ohio area near Lima. The meteor moved north-northwest at approximately 49,900 mph before disintegrating above the area just west of Lansing, Michigan.

UPDATE: NASA - National Aeronautics and Space Administration can confirm a fireball over New England at 2:06 p.m. EDT on Saturday, May 30, 2026. The meteor was about 5 feet (1.6 meters) in diameter with a mass of 5.6 metric tons and entered Earth’s atmosphere at roughly 42,000 mph.

The meteor traveled through the atmosphere from northwest to southeast for 26 miles before breaking up at an altitude of 31 miles and producing a meteorite fall into Cape Cod Bay.

Based on the latest data, the energy released at breakup is estimated to be equivalent to about 230 tons of TNT, which accounts for the sonic boom.

It’s ! Here’s your space weather report for the week of May 22 - 28:
• 1 M-class flare
• 0 C-class flares
• 46 coronal mass ejections
• 0 geomagnetic storms

This video from NASA’s Solar Dynamics Observatory (SDO) shows the week’s activity. Most of the action this week was on the far side of the Sun, out of SDO’s view. However, we do see a good example of a prominence beginning at about 20 seconds into the video on the lower western limb (right side edge) of the Sun. Prominences are huge clouds of electrified gas called plasma suspended in the solar atmosphere.

: Eyewitnesses in New England and National Oceanic and Atmospheric Administration (NOAA)'s GOES-19 satellite reported a bright fireball on Saturday, May 30, at 2:06 p.m EDT accompanied by a loud noise. The meteor appears to have fragmented at an altitude of 40 miles over northeastern Massachusetts and southeastern New Hampshire. The energy released at breakup is estimated to be equivalent to about 300 tons of TNT, which accounts for the loud noise.

It’s ! Here’s your space weather report for the week of May 15 - 21:
• 4 M-class flares
• 3 C-class flares
• 35 coronal mass ejections
• 1 geomagnetic storm

This video from NASA’s Solar Dynamics Observatory (SDO) shows the week’s activity.

It was a fairly calm week on the Sun. A coronal mass ejection last week reached Earth on May 15, triggering a minor geomagnetic storm and leading to aurora sightings across the northern U.S.

On May 20, SDO's Helioseismic and Magnetic Imager (HMI) paused normal science operations for a series of routine calibration maneuvers — measurements that keep the instrument's magnetic field and Doppler velocity data scientifically accurate. You can see these maneuvers starting at about 2:29 in the video.

It’s ! Here’s your space weather report for the week of May 8 - 14:
•1 M-class flare
•1 C-class flare
•31 coronal mass ejections
•0 geomagnetic storms

This video from NASA’s Solar Dynamics Observatory (SDO) shows the week’s activity.

The active region we spotted last week (which erupted with an M-class flare and a CME last Sunday) has moved across the Sun and is now center-disk. It’s right next to a coronal hole that unleashed a stream of fast solar wind to Earth. We’ll be watching both regions for continued activity this week.

It’s ! Here’s your space weather report for the week of May 1 - 7:
•2 M-class flares
•2 C-class flares
•29 coronal mass ejections
•1 geomagnetic storm

This video from NASA’s Solar Dynamics Observatory (SDO) shows the week’s activity.

It has been a relatively quiet week on the Sun, with the two M-class flares erupting off the Sun’s western limb (right side from SDO’s view) and not producing much impact on Earth. However, a large active region will soon be rotating into Earth’s view — you can see it toward the end of this video emerging from the eastern limb (left side from SDO's view). Keep an eye out in the coming week for potential solar activity!

It’s ! Here’s your space weather report for the week of April 24 - 30:

• 2 X-class flares
• 14 M-class flares
• 18 coronal mass ejections
• 0 geomagnetic storms

This video from NASA’s Solar Dynamics Observatory (SDO) shows the week’s solar activity. Two X-class flares erupt on the right side of the disk at the beginning of the week. On April 29, a few spacecraft calibration maneuvers make it look like the Sun is dancing.

: Eyewitnesses in Oregon and Washington and the Canadian province of British Columbia reported a bright fireball on Wednesday, April 29, at 12:12 a.m. PDT. The meteor was first visible over Oktwanch Peak on Vancouver Island. It moved southwest at 66,000 mph before fragmenting above the Pacific Ocean, about 20 miles west of the town of Yuquot.
