This is done to maintain health and trending data on both SSRs for the remainder of the mission, as well as lower thermal output during the “hot season”. For trending and analysis purposes, the swap will typically be aligned with the bi-annual report periods: Feb – July = SSR-B prime Aug – Jan = SSR-A prime However, operational conditions may dictate SSR swaps at other times as well.

Radiation (Geophysical Activity): The geomagnetic field is expected to be at quiet levels on days one, two, and three (02 Feb, 03 Feb, 04 Feb). Protons greater than 10 Mev have a slight chance of crossing threshold on days two and three (03 Feb, 04 Feb). Space Weather is unsettled. Region AR 4366 has had multiple significant flare events over the past 48 hours, four being X-class flares, one being an X8 flare around 7 pm, and a longer duration X1.6 flare this morning. As for CME's, there is now a faint partial halo CME associated with the X8 that predicts only a weak glancing blow arriving midday on February 5th. The X1.6 this morning has not yet been associated with any CME. We are currently at around a 40% chance for futher X-class flares. MP: TOO approved. Currently looking to schedule near the start of the FEB0926A loads. ENG: No issues. GOT: No issues.
