Solar Stormwatch Community Poster

SSW_thumb

As part of the Zooniverse’s Advent Calendar we’ve been producing massive, author posters, built up of the names of the people who take part in our various projects. Solar Stormwatch’s community poster is Day 14 of our calendar and features an image not from STEREO but from NASA’s Solar Dynamics Observatory (SDO).

This image was taken about 17:50 UT on December 6th this year. The prominence seen in this image is nearly a million kilometers across! Although the entire Earth would be just a few pixels tall on this image, the 25,000 volunteers who gave their permission to have their names published by the project are found written larger than this in 12pt font!

You can download the image in a large 5000-pixel size (22 MB) or in a smaller 3000-pixel size (8 MB).
