SDO Day 44: Spacecraft Jitter Tests
Fri, 26 Mar
Thursday was spent testing the "jitter" of the observatory. Why do we care? SDO needs to keep its imaging telescopes pointed at the Sun with a steady hand. Our pixels image an area of the Sun that is about 0.5" across. While that's a patch the size of New Mexico on the Sun, it easier to think of it in terms of a quarter. Check log of events so far here
