Current Space Weather Risk Console

A compact readout built from public NOAA/SWPC JSON products. Values refresh when the page loads and gracefully show unavailable if a source blocks or times out.

Sources: NOAA/SWPC GOES X-ray and particle flux, planetary Kp, real-time solar wind, active regions, and flare probability products.

Space Weather Overview

Click any panel to zoom the source image. These NOAA/SWPC products summarize current solar radiation, geomagnetic activity, and solar wind conditions without hiding the feeds inside a collapsible block.

SWPC Overview

How to read it: X-ray flux tracks flare class, proton flux shows radiation storm risk, and Kp summarizes global geomagnetic disturbance. A sharp X-ray rise followed by proton or Kp response can signal a more consequential solar event.

Station K Index

How to read it: K values are local, three-hour disturbance levels. They are useful for seeing whether geomagnetic activity is regional, rising quickly, or sustained across multiple observation windows.

Station A Index

How to read it: A values compress the day into a more linear activity estimate. Use it as the daily context behind shorter K-index changes and longer geomagnetic storm periods.

ACE MAG & SWEPAM

How to read it: Watch Bz most closely. A sustained negative Bz lets solar wind couple into Earths magnetic field; high speed and density can strengthen the geomagnetic response.

SDO Solar Wavelength Explorer

Flip through SDO wavelengths in one viewer. Each channel highlights a different solar layer, temperature range, or activity type. Magnetic field-line images are included for the selected wavelength where SDO provides a PFSS overlay.

Magnetic Field-Line Overlay

PFSS field-line overlays show modeled magnetic connectivity above the visible solar disk. They help connect loops, active regions, and coronal-hole structure with the selected wavelength.

Coronagraph Explorer

Coronagraphs block the bright solar disk so the faint outer corona and outward-moving CMEs can be seen. Use this viewer to compare GOES-19 CCOR-1, LASCO C2, and LASCO C3 in one place.

Sources: NOAA/SWPC CCOR-1 and SWPC-hosted SOHO/LASCO imagery. Coronagraph products update as source data is available.

Live Sunspot Watch

A modular view of visible-disk magnetic structure, NOAA-numbered active regions, and farside sunspot monitoring resources. Region numbers in the Active Region Watch table link to the NOAA region locator model below.

SDO HMI Magnetogram

Source Full Resolution

How to read it: HMI maps line-of-sight magnetic polarity. Bright contrasting patches mark active regions where complex magnetic fields can store flare-producing energy.

NOAA Active Region Locator

Model source: NOAA/SWPC solar_regions.json. This lightweight disk model plots current NOAA region numbers from the same feed used in the Active Region Watch table.

Far Side Sunspots

Stanford Farside Monitor

Far-side active regions are inferred using helioseismology: acoustic travel-time shifts reveal large magnetic regions before they rotate onto the Earth-facing disk. Use this as early context alongside NOAA numbered regions.

Satellite Charging Hazard

These SEAESRT products show the near-Earth radiation environment and spacecraft charging risk. Click any panel to zoom in for operational reading.

Orbit Environment

How to read it: Use this as the map/context layer. It helps relate spacecraft altitude and location to radiation belt structure and changing near-Earth particle conditions.

Charging Hazard

How to read it: Stronger hazard colors indicate a greater charging environment. Risk can rise during geomagnetic disturbances when energetic electrons are enhanced.

Hazard Quotient 0E

How to read it: Rising values mean the modeled charging hazard is increasing for that longitude sector. Compare sectors to see whether risk is localized or broad.

Hazard Quotient 90E

How to read it: This longitude slice helps identify whether hazardous charging conditions are rotating into or out of a particular orbital sector.

Hazard Quotient 180E

How to read it: Compare this panel with the other longitudes to spot delayed or sector-specific hazard increases after geomagnetic activity.

Hazard Quotient 270E

How to read it: Use alongside the other sectors to determine whether spacecraft charging risk is persistent, drifting, or tied to a specific longitude region.
