This behavior is expected in cold attitudes, since camera body heater is now off. The survival heater toggles off and on, the yellow limit violations are an indication of this toggling. - Had another incidence of FID light dropout, as reported in Flight Note 464. SSWG will look at this and update the flight note if necessary. SOT/Radiation: - ACE solar protons are very low (< 100). - Solar Activity Forecast: Solar activity is expected to be very low. - Geophysical Activity Forecast: The geomagnetic field is expected to be quiet to unsettled with isolated active levels at mid-latitudes and isolated minor to major storm conditions at high latitudes for day one (10 April), due to persistent effects from the high speed stream. Conditions should return to quiet to unsettled levels for day two (11 April) as the influence of the high speed stream is expected to wane. Conditions should be predominantly quiet on day three (12 April).
