Space weather today: observations versus active alerts
Today's space-weather view is built around two clocks: when a physical metric was observed and when an official product was issued or expires. A page-load timestamp cannot substitute for either one. The view also avoids describing conditions as quiet when the observation feed or alert feed has failed, because absence of evidence is not a measured low value.

Current evidence
Latest verified observation and alerts
The current panel will show an observed K-index separately from active G, S, or R products, retaining the official timestamps and product codes. Each feed can fail independently.
The latest normalized NOAA products are unavailable through the public read boundary. No current K-index, active-alert count, or quiet-condition statement is displayed until both provenance and freshness can be verified.
Latest observed conditions
Why an alert and an observation are not interchangeable
An observation reports a measured value for a completed interval. An alert, watch, warning, or summary can describe expected or ongoing conditions using a product-specific lifecycle. Combining them into one unlabeled number would erase whether a claim was observed, issued, updated, or expired.
A reliable daily view preserves this lifecycle and shows partial availability when only one feed succeeds. It does not recycle yesterday's alert as active or infer calm conditions from an empty response. Operational users should consult NOAA SWPC directly because this page is explanatory and not a replacement for product delivery.
Methodology
Today's evidence checklist
Observation time
The physical measurement interval determines freshness, not the time the page was opened.
Product lifecycle
Issue, update, and expiry fields determine whether an official alert remains active.
Partial availability
One successful product cannot hide a failure or delay in another required feed.
Freshness state
What makes today's conditions stale
Observed metrics and alerts use separate freshness checks. A delayed feed is labeled and reduces completeness; an expired product is removed from current interpretation instead of being carried forward.

The public source registry is unavailable. Source decisions remain fail-closed.
| Source | Rights decision | Production state | Attribution and limits |
|---|---|---|---|
| NOAA Space Weather Prediction Center | Approved | Not enabled for production | Space-weather observations and alerts are attributed to NOAA SWPC with issue, observation, and expiry times where supplied. Approved production products. Conditions can change quickly, so delayed or missing observations cannot be described as quiet space weather. |
