Loads good through: 2026:293:10:42:01 TECH DR's Created: Problem| Impact| Cause| Resolution ---|---|---|--- Out of the building for AOS/BOT due to an unannounced building fire alarm test, and CC EHS account had to be rebooted for commanding to work. Delayed 12 minutes before sending our first successful command. (OC account)| Building fire alarm testing occured 2 minutes prior to AOS (alarms as well as lights). Evacuated the building for ~9 minutes. Upon return, the CC EHS machine had to be rebooted to send commands. (OC machine sent initial commands to keep support moving SOH, Backstop checks, and SSR P/B. Radiation (Solar Activity): Solar activity is expected to be low with a slight chance for an M-class flare on days one, two, and three (16 Oct, 17 Oct, 18 Oct). Radiation (Geophysical Activity): The geomagnetic field is expected to be at quiet to unsettled levels on day one (16 Oct) and quiet levels on days two and three (17 Oct, 18 Oct). MP: OCT1926 loads were approved. ENG: No issues. GOT: No issues.
