NASA’s Webb Telescope Reaches Major Milestone as Mirror Unfolds

Saturday, 08 January 2022

NASA’s James Webb Space Telescope team fully deployed its 21-foot, gold-coated primary mirror, successfully completing the final stage of all major spacecraft deployments to prepare for science operations.

Solar Activity
Solar flare activity has been at low levels. There have been five C-class flares with most of the activity coming from newly numbered Region 3916 (S16E72, Cai/beta). Region 3906 (S16W76, Eko/beta-gamma) and Region 3912 (S05E11, Eai/beta) both produced C-class flares, the largest being a C6.1 at 03/0544 UTC from Region 3906. There have been no Earth-directed CMEs observed in available coronagraph imagery.
Solar Wind
Solar wind parameters reflected the arrival of a weak CME early in the period and have been enhanced since. Total magnetic field was between 12-14 nT early on and has remained around 10 nT for most of the period. The Bz component varied between -7 and 12 nT. Solar wind speeds have averaged around 420 km/s. The phi angle has been mostly positive (away from the Sun) but has had three transitions into the negative for about 2-4 hours at a time.
Energetic Particle
The greater than 2 MeV electron flux was at normal to moderate levels. The greater than 10 MeV proton flux remained at background levels.
