Clouds and other weather phenomenon.

Rainbow. 24th March 2005 at 17.30 hrs. An arch in the sky consisting of a series of concentric arcs of the colours red, orange, yellow, green, blue, indigo, and violet. They form especially opposite the Sun by refraction,reflection, and interference of light rays in raindrops and spray. The raindrops act like tiny prisms. As in this picture a double rainbow may often appear.

On the evening of March 13th 1989 the Aurora Borealis, the northern lights were seen as low as Latitude +48. (north). A truly wonderful display. They are caused by incoming electrons from powerful solar emmisions such as SMC's ( solar mass ejections). They arrive at our upper atmosphere at speeds of many 100's of km's per hour. The electrons excite the molecular gases in Earths upper atmosphere such as oxygen and nitrogen. These encounters occurs at between 80 and 1000 km altitude. The red and green glows are from the excited oxygen, the blue from the interactions with the nitrogen. Taken by myself at my Mount Tuffley Observatory. IAU code J93, and Tuffley Weather station.
