Big sunspot AR1520 unleashed an X1.4-class solar flare on July
12th at 1653 UT. Because the sunspot was directly facing Earth at
the time of the blast, this is a geoeffective event. Stay tuned
for updates about possible CMEs and radio blackouts. <strong></strong></p>

of extreme ultraviolet radiation from the blast site:</p>

partially ionized Earth's upper atmosphere on the dayside of our
planet, disturbing the normal propagation of radio signals.<br>
