Storms, data-analysis and fruitcake
Thanks to everyone who helped track the most recent bunch of solar storms. Several of them came by Earth but their magnetic fields were mostly the same polarity as Earth’s and when this happens, just like in the school experiment, the two magnetic fields just bounce off each other. I was amazed that we could track an Earth-directed storm at all from where the spacecraft are now, particularly with the gaps now appearing in the data coverage in incoming-traceit. You are really showing us what the limits are on our mission! Keep tracking the real-time events though. Even if we can’t track them to Earth very easily we can still test out our tracking skills by watching them go by other planets. We have spacecraft around all the inner planets at the moment:- Messenger at Mercury, Venus Express at Venus, the sister-craft to Mars Express which (amongst others) is orbiting Mars.
Thanks to your efforts we now have two publications that used your clicks to help track storms and dust. The next task we’re aiming to do is to analyse the huge amount of data you have processed in the trace-it archive. With this dataset we hope to track each storm in detail as it expands out into the solar wind. Experts like Solar Stormwatch’s own Neel Savani can turn your clicks into a comprehensive survey of all the storms we have seen. Not only will this analysis tell us how fast and how big each storm was, it should also reveal how much it was distorted by the solar wind into which it was expanding – vital information in tracking their progress towards our planet.
So, please keep clicking on trace-it archive data too. The real time stuff may be the most exciting but the careful consideration of the archived data will be an important part of the Solar Stormwatch legacy too.
And the fruitcake? Ah… I appear to have eaten the last photograph of one that Jules posted to the forum… sorry.
Thanks once again for all your enthusiasm, time and efforts. It really is a privilege working with you all.
