Mission Operations Update #3

Winds and UV products all published

The MIGHTI 2.1 Line-of-Sight winds and 2.2 Cardinal winds have been updated to v4 and are now available out to November 13 2020. The version resolves a disagreement between the green and red winds that became apparent in the June 2020 timeframe, and extends the set.

Some gaps will be apparent in this set and they are due to 3 things, that the image below describes.

Data gaps in v4 winds

Data excluded for Lunar contamination are recoverable, and will be processed with new L1 files and v5 L2 processing early next year. Data absent during the star tracker anomaly were not taken. Data excluded for solar contamination are partially recoverable, and will be addressed to the degree possible with new L1 files and v5 L2 processing early next year. An example link is reported below.
