EPH temp 57.17 F NOTES/ISSUES/PROBLEMS From the 9am status meeting: Two supports in the preceding 24 hours. No issues. CAP 940 was executed to replace the on-board loads with the new OCT0704B ToO loads. Three load segments were uplinked, on-board loads good until 284:23:42. OCT1104B will be re-run for continuity today, products out for an email review by the end of the day. There will be fire alarm testing today.
