Crescent Moon + Coronal Mass Ejection

As last night Jupiter, Venus and the crescent Moon were bright in the sky. When I looked tonight they were no longer in line. Venus appears much nearer to the Moon in the sky:

A bit more of the Moon was visible and I could still make out its full circular shape, which was difficult to capture with the camera: You can just make it out on the first photo.

Coronal Mass Ejection (CME)
I have just seen a report that a CME from the Sun will hit the Earth's magnetic field on Feb 26th at 13.30 UT +/- 7 hours. This could cause a G2 class magnetic storm with Auroras seen as far south as 55 degrees North.

    The last couple of posts are really good quality. Have you tried bracketing at -1 to +1? It should work in Photomatix.

    I hadn't even thought of that Adrian. Will see whether there is another clear night tonight.
