I thought about mentioning this, plus with the X5 today on top of the current activity it could get interesting.

I've been keeping an eye on this for the past few hours ever since Calsky sent me an alert. Even with the moon out there is a strong possibilty of aurora being seen as far south as the Midlands tonight.

Another CME is expected to hit tomorrow morning according to SpaceWeather.com -- News and information about meteor showers, solar flares, auroras, and near-Earth asteroids so there could be activity for a couple of nights.

Cool. I've been watching that offending sunspot for the last few days.

Please help me out here

What sort of times are they expected?

[Hypernova]

According to Space Weather the IMF (Interplanetary Magnetic Field) has switched its polarity to north which has reduced the chances of aurora for the time being. Recalling what I heard on last night's Horizon program is that a southern-polarity magnetic field has a better chance of producing aurora as it opposes Earth's own northern-orientated magnetic field.

According to the latest WSA-Enlil model, Earth arrival of this morning's CME is around 0900 UTC Thursday.

That is only run when a CME occurs.

So Horizon on the BBC last night was very well timed or what?
