NOCTILUCENT CLOUDS FROM SPACE: This week, sky watchers near the Arctic Circle have reported nightly displays of bright noctilucent clouds.  The silvery ripples of NLCs look amazing from the ground, but they look even better from space. 

Regular readers of Spaceweather.com have been waiting for this image since June. Normally, AIM  transmits pictures of NLCs every day, but the regular flow of data was interrupted months ago. The reason has to do with the spacecraft’s orbit. Since AIM was launched in 2007, its orbit has been precessing–that is, slowly rotating with respect to the planet below. Eventually, accumulated changes in AIM’s orbital elements required a new way of pointing the spacecraft’s instruments. Mission controllers have been working on that problem all summer long–and it has finally been solved.
