Did you know? Here's a space weather and radio propagation educational tidbit -- from http://nw7us.us/swc -- at 14:00 UTC on 2015-03-28:

The ionosphere's D-region lies between abt 50 and 90 km, and is 'strongest' during daytime. The ionosphere's D-region is ionized by high-energy cosmic rays and with hard x-rays.

Cosmic rays occasionally follow strong solar proton flares, ionizing the D-region. Hard x-rays are also known as Lyman Alpha radiation; this ionizes the D-region.
