Quick answer

Sunspot Region 4549, a fast-growing group facing Earth, produced an M1.4 solar flare at 2:10 AM ET and an M1.8 at 4:05 AM ET on October 6, 2026, according to NOAA. A Type II radio burst at 947 km/s during the first flare suggests a coronal mass ejection may have launched, but none aimed at Earth is confirmed. NOAA has issued no geomagnetic storm watch.

Evidence
Verified

Region 4549 produced an M1.4 flare peaking at 06:10 UTC and an M1.8 flare peaking at 08:05 UTC on October 6, 2026.

Verified

A Type II radio emission with an estimated velocity of 947 km/s began at 05:59 UTC on October 6; such emissions typically indicate a coronal mass ejection.

NOAA's 3-day forecast issued at 00:30 UTC on October 6, before the two flares, expects a maximum Kp of 4 and no G1 storm for October 6 to 8; an Earth-directed CME is not confirmed.

A sunspot group that emerged only in the past few days fired two M-class solar flares within two hours before dawn on Tuesday, October 6. NOAA's Space Weather Prediction Center recorded an M1.4 flare peaking at 2:10 AM ET and an M1.8 at 4:05 AM ET, both from Region 4549, which sits near the center of the Sun's disk and faces Earth. During the first flare NOAA also logged a radio burst that often accompanies a coronal mass ejection (CME). As of this writing, no geomagnetic storm watch has been issued and no Earth-directed CME is confirmed.

What happened on the Sun

The sequence began on Monday afternoon. According to NOAA's Forecast Discussion issued at 00:30 UTC on October 6, neighboring Region 4545 produced an M1.0 flare at 18:48 UTC on October 5 (2:48 PM ET) after a phase of rapid growth. The same discussion noted that Region 4549 was gaining spots and had developed a mixed-polarity magnetic layout with a weak "delta," and the joint USAF/NOAA Solar Region Summary classed it beta-gamma-delta, the most complex category on the scale. At that point NOAA put the chance of further M-class flares at 15 percent.

Region 4549 then beat those odds twice. NOAA's event list for October 6 shows a long M1.4 flare that began at 05:38 UTC, peaked at 06:10 UTC and ended at 06:51 UTC, a span of 73 minutes. At 05:59 UTC, in the middle of that flare, ground stations picked up a Type II radio emission with an estimated speed of 947 km/s (NOAA alert ALTTP2, serial number 1530). A second, sharper flare followed: M1.8, peaking at 08:05 UTC and over within 26 minutes.

An M1 flare corresponds to an R1 (Minor) radio blackout on NOAA's five-step scale, meaning brief degradation of shortwave radio on the sunlit side of Earth. At 2 AM and 4 AM Eastern, the sunlit side was Asia, the Indian Ocean and East Africa, not North America. EarthSky's daily Sun report for October 6 places the blackouts over the Indian Ocean and the Arabian Sea and says analysts are modeling the flares to see whether any launched a CME with an Earth-directed component. Spaceweather.com describes the region as growing rapidly and absent from the disk shortly before.

Why forecasters are watching this one

Three details make Region 4549 more than a routine entry in the log. First, its position: NOAA listed it at N10E15 on Monday night, close to the middle of the disk, so anything it throws out has a direct line toward Earth for the next several days. Second, its magnetic complexity. Third, the Type II radio emission. NOAA explains in its alerts that these emissions occur in association with eruptions on the Sun and typically indicate that a CME accompanied the flare. The direction of any cloud still has to be worked out from coronagraph images.

Known Two M-class flares from Region 4549 on October 6; Type II radio burst at 947 km/s; region faces Earth
Not yet known Whether a CME left the Sun, and whether any part of it is aimed at Earth
Official outlook NOAA's 3-day forecast (issued 00:30 UTC, before the two flares): highest expected Kp 4, no G1 storm expected October 6 to 8

If a CME is confirmed and aimed our way, such clouds usually need one to three days to cross the distance, which would put any effect in the second half of this week. Flares of this size pose no danger to people on the ground. The stream of fast solar wind behind the G2 geomagnetic storm of October 4 is fading at the same time, so Earth's magnetic field is calming down just as the Sun becomes more active.

What it means spiritually

Facts first: a solar flare is a burst of radiation, measured by satellites, and nothing in the data says it shapes anyone's mood, luck or decisions. What follows is tradition and interpretation.

In astrology the Sun stands for vitality, will and the visible self, and it is currently in Libra, the sign of the scales. Readers who work with that language may enjoy the picture: a new, tangled knot of energy appears on the face of the Sun and discharges in the very week the Moon thins toward the new moon in Libra on October 10. Many traditions treat the dark of the Moon as a time to release tension before something begins, and the image of a sunspot shedding stored magnetic stress fits that mood well. Whether solar activity is felt in the body is a separate question that we cover, with the studies, in Do Solar Storms Affect Your Body?

What you can do now

  • Check the official word tonight. NOAA updates its Forecast Discussion twice a day. If a watch is issued, it will appear on the SWPC homepage first.
  • Keep Thursday and Friday night loosely free. No aurora is forecast right now. If that changes, the timing is kind: the Moon is a thin waning crescent and new on Saturday, so skies are dark.
  • Look at the Sun safely. NASA's Solar Dynamics Observatory posts fresh images around the clock at sdo.gsfc.nasa.gov. Never look at the Sun directly or through unfiltered optics.
  • Try a five-minute discharge practice. Write down one tension you have been carrying in a tangle, name its two opposing pulls, and decide which small action would let some of it go this week.
  • Stay with the numbers. M1.8 is a moderate flare. Headlines that promise blackouts or disaster from this event are not supported by the data.
