But an eclipse does not last for very long so the effect will be very small. Granulation has a lengthscale of around 700 km, so that is quite small. Spacelab II, operated by the Lockheed group, managed to observe granules with a 25cm aperture telescope, but that was from space. I would have thought the chances would be small. I have heard that solar flares tend to run in cycles.
Solar flares run with the solar cycle.
As for prominences, some eclipses show prominences and others don't. That's all the time we have for questions today for Jack Ireland. Check there often and we hope to see all of you at other events. Thanks for being with us. That's all the time we have for questions today for Jack Ireland.
