It's pretty well known there are various skip layers in the ionosphere. With solar flares, we sometimes get the layers energized, and they become like mirrors for radio-frequency waves. It's covered in a lot of sources, the ARRL handbook is a trusted one. This case probably used the F2 skip layer energized by a flare at the time. If you have a question, AMA, I'll be glad to help.
