Current GOES X-ray flux class

Solar wind speed and magnetic field strength indicate current space weather activity. Elevated or storm-level readings can disrupt satellites, GPS accuracy, and power grids. This is a planetary-scale signal, not specific to this location — typical quiet conditions run under 400 km/s wind speed and under 5 nT magnetic field.

Source: NOAA SWPC (planetary signal, same for every location)

Sources: USGS (earthquakes), Open-Elevation (terrain), Open-Meteo (weather). Illustrative estimate, not a certified engineering or actuarial assessment.

No country-specific deep dive built yet for Cuba. Global baseline data above still reflects real, live USGS and elevation data for this exact coordinate.
