[QUOTE="m0lsx, post: 165495, member: 29323"] When I took my full (Advanced) Amateur Radio exam a sizeable percentage of the questions related to the Ionosphere & how radio waves behave within it. And part of the how & why of the Ionosphere is Solar Weather. The sun not only warms us up, it also warms the Ionosphere up & when it does the Ionospheres F1 & F2 layers separate & make very long distance shortwave transmissions possible. To give some idea of what space weather is. In 1941 a massive soalr geomagnetic storm hit the world knocking out shortwave transmissions, causing beautiful Northern Lights & resulting in power levels surging within electrical networks. It was the most powerful storm ever recorded. In March 1989 during an incredibly cold period in Canada an electromagnetic storm hit the earthjs atmosphere, causing a 9 hour power outage in the Quebec area. Solar weather has the power to heavily effect us here on Earth. The Northern Lights may look beautiful. but the cause, Solar (electromagnetic) winds, have the power to blow power stations electrical systems, knock satellites & even aircraft out of the sky & black out mobile phone & internet communication. Dr Tamitha Skov is the Space Weather Woman & she makes some fascinating reports on her youtube channel.
