Solar Storm
Right now
The most recent data we hold from NOAA Space Weather Prediction Center (GOES) arrived 4 minutes ago, and this point is not in it. We record detections, not passes: an absence is not proof that nothing is there.
Reported by NOAA Space Weather Prediction Center (GOES) 4 days ago.
What the source measured
NOAA Space Weather Prediction Center (GOES) reported: M1.9 solar flare detected by GOES X-ray sensor. Peak flux: 1.90e-5 W/m². Moderate solar flare. Minor HF radio effects on sunlit side of Earth.
How we know
2 recorded sources include NOAA Space Weather Prediction Center (GOES); independence is not established by this count.
Our own score for this event is 31 out of 100.
This is our versioned heuristic index, not source severity or a calibrated probability. Urban PEI does not count unique people.
Computed under scoring rules v5. Rows carrying other versions were judged by different rules and are not directly comparable.
Series begins 8 March 2026. Comparisons refer to that period only. Collection gap: 14-26 August 2026.
This data is aggregated algorithmically from scientific sources. Not a replacement for official emergency warnings.

Safety information
What to do in a solar storm
A solar storm is not dangerous to people on the ground: it can disturb power, radio and satellite navigation. What to do, from FEMA’s Ready.gov.
For this reportSolar Storm
Nothing to fear outdoors
The atmosphere protects people on the ground; you may even see an aurora.
NOAA SWPCBe ready for a power cut
Torch, batteries, charged phone, and a plan for medical devices that need power.
Ready.govDo not rely only on GPS
Satellite navigation and radio can be wrong or drop out for a while.

Before, during, after. Here it is “after”.
Before · When a storm is forecast
Charge what matters
Phones and power banks.
Medicines and devices
Ask your doctor how to store medicines and run devices without power.

During · During the storm
Save electricity
If authorities ask, to avoid rolling blackouts.

After · After a long power cut
Check the food
Throw away what stayed above 4 °C for more than two hours.

Questions people ask
Is a solar storm dangerous for my health?
No, not on the ground. It concerns power grids, satellites, radio and, at high latitudes, aircraft crews. Source: NOAA Space Weather Prediction Center.
Will I see the northern lights?
In strong storms the aurora can be seen far from the poles. Look north (south in the southern hemisphere) on a dark, clear night.
