Solar Storm
Right now
The most recent data we hold from NOAA Space Weather Prediction Center (GOES) arrived 21 hours 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) 47 days ago.
What the source measured
NOAA Space Weather Prediction Center (GOES) reported: M1.0 solar flare detected by GOES X-ray sensor. Peak flux: 1.04e-5 W/m². Moderate solar flare. Minor HF radio effects on sunlit side of Earth.
How we know
One source: NOAA Space Weather Prediction Center (GOES). Not yet confirmed by a second, independent source.
Our own score for this event is 22 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 v1. 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.

Urban PEI is distance-weighted and does not count unique people; zero does not establish that nobody is present. Model cards.

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 · 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.
