Sunspots
27th October 2003
The following images were captured at noon on the 27th October
2003 by Graham Ensor. He used a Mavica digital camera to photograph the image of the Sun projected
by his 3-inch Watson and Sons 'Century' refractor. The image was then processed in Photoshop.
Sunspot numbers are given. The ring shaped circular sunspot group 488 produced a major solar storm which
caused enhanced aurorae, radio disruption and the malfunction of two Japanese satellites.
