| GN-2008A-Q-8-4-003 | 2008-02-14 11:12:48 | The cirrus is definitely much thinner that it was when the standard star was taken. |
| GN-2008A-Q-8-4-004 | 2008-02-14 11:23:29 | Sky continues to clear, but from the guide trace there is still occastionally some cloud passing overhead so we will stay here for the time being. |
| GN-2008A-Q-8-4-005 | 2008-02-14 11:34:12 | more guide count fluctuations but still well withing CC70. |
| GN-2008A-Q-8-4-007 | 2008-02-14 11:49:25 | this exposure has significantly more clouds, CC90 at best. Setting to USABLE. |
| GN-2008A-Q-8-4-008 | 2008-02-14 12:12:34 | Resumed observation after waiting for clouds to pass but they came back through midway through the exposure. This observation is on the edge between CC70 and CC90, I'll pass it for now but if I get another exposure that's this affected by clouds I will take another image to compensate and bring up the signal to noise. |
| GN-2008A-Q-8-4-009 | 2008-02-14 12:23:16 | The counts were quite low for much of this exposure then they came up at the end. I'll set this one to USABLE and add another exposure to compensate. |
| GN-2008A-Q-8-4-011 | 2008-02-14 12:38:29 | counts started back up at max and fluctuations were much less severe, staying within CC70 until the last 30 sec when the dropped again, paused the sequence again and waited for the counts to come back up. |
| GN-2008A-Q-8-4-012 | 2008-02-14 12:49:34 | more thick clouds in this exposure, borderline CC70 |
| GN-2008A-Q-8-4-013 | 2008-02-14 13:00:16 | once more thick variable clouds interspersed with relatively clear patches. Since this exposure and 245 make up another pair of borderline CC70 observations I'll mark this one USABLE and take another to compensate. |
| GN-2008A-Q-8-4-015 | 2008-02-14 13:36:01 | highly variable counts for the first half but clear skies for the last two minutes. |
| GN-2008A-Q-8-4-016 | 2008-02-14 13:46:43 | counts were much more stable for this exposure, decreased throughout but never fell below 67% of max. CC70. |
| GN-2008A-Q-8-4-017 | 2008-02-14 13:57:25 | counts were stable for the first 3 minutes then rose during the last 2 minutes. Solidly CC70. |
