[01:47:47] Clouds have begun to obscure the target
[01:56:01] Captures of Iota Her completed
[01:56:40] Waiting until the target is visible again to brgin next capture
[02:39:29] Alpha lac is visible but is going in and out
[02:39:58] Completely obscured now. Waiting until 0300 to call it
[02:41:16] Starting captures of Alpha Lac
[02:58:26] Getting some semi-consistent visibility on the targets.
