NASA SDO latest solar image
Updated every 15 minutes from Solar Dynamics Observatory. Each wavelength captures a different layer of the sun — 304Å the chromosphere, 171Å the quiet corona, 193Å hot corona and flare plasma, 211Å active regions in iron purple.

Kp is the global geomagnetic activity index, 0 to 9, updated every 3 hours from eight worldwide magnetometers. Above 5 and geomagnetic storms are in progress — aurora visible further south, HF radio communications degraded, GNSS precision reduced.
