 The 27 October 2023 Flight Engineer Report indicates that aircraft descending to 19.5 kft at 11:01 UTC to sample clouds at the -10 ºC level. A 19.5 kft sample is conducted at 11:12 (40,320 sfm) UTC. After missing the cloud at 11:14 pass, the same clouds is sampled at 11:16 (40,560) UTC at 21.0 kft. Hence, there are two passes of cloud 20231027A. A new clouds is located at 11:23 UTC. Cloud 20231027B is sampled at 22 kft  at 11:33 (41,580 sfm) UTC, at 23 kft at 11:37 (41,820) UTC, and at 24 kft at 11:42 (42120) UTC. The 27 October 2023 Flight Engineer Report indicates that aircraft descending to 19.5 kft at 11:01 UTC to sample clouds at the -10 ºC level.
