Sunspots

For the past two Thursdays I have been demonstrating the Solar Prominences experiment in first year lab. Amazingly, both weeks have been cloud free (well amazing for Manchester) so they were able to take images of the Sun both weeks. The first week was disappointing because there weren't really any sunspots visible. However, on Thursday we were able to observe one of the largest groups of sunspots seen for years - the first years are supposed to calculate the rotation rate of the Sun from measurements of the position of sunspots over time. Unfotunately their images from this Thursday don't show the sunspot group as they didn't save them properly.

The current large group will probably have moved out of sight by the time the next group start next Thursday so I might go in to the department to take an image tomorrow if the weather improves.
