The spacecraft is performing well and all systems are operating nominally. We continue to have frequent periods of uplink receiver bitlock. The teams at Orbital and LASP are working on the On-Board Computer patches that will be loaded to the Electronically Erasable Programmable Read-Only Memory (EEPROM) over the next few weeks. This patch load will continue to improve our operations and help mitigate the lack of uplink receiver bitlock.
The SOFIE instrument continued nominal operation and 100% collection of science measurements. Data quality is excellent and unchanged. Successful adjustment of sun sensor integration time for center pixels was accomplished Saturday the 19th to improve the linearity of sun sensor measurements. These data are used for inferring stratospheric transmission profiles, which are incorporated in the edge detection algorithm.
Processing of 2 days, April 11 and 12, was delayed due to an error in ephemeris data, which has been resolved. Processing of those days is expected early next week. All algorithm improvements are on schedule.
No problems are anticipated and nominal operations are expected to continue indefinitely.
CIPS continues to provide excellent science data from all four cameras. Further, our analysis of on-orbit calibration data shows that camera sensitivity has changed less than 0.5% since launch. CIPS data sequencing automatically switched from the Southern to Northern Hemisphere on the first day of spring, as planned
CDE is on and collecting dust impact data following the completion of the Recovery ATS. Temperatures and voltages are nominal. CDE Version 2 data processing is being implemented for Levels 1 (Charge) and 2 (Mass).
