Sunspot AR2816 has produced another solar flare–this time a C3.8-class eruption on April 22nd (0435 UT). A pulse of X-rays and UV radiation ionized the top of Earth’s atmosphere, producing a minor shortwave radio blackout over southeast Asia. NASA’s Solar Dynamics Observatory recorded a shock wave rippling away from the blast site; this suggests a CME is heading our way.
Stay tuned for updates.
