| | 353 | Clear, warm (11 deg), and no wind at 5 UT. Winds gradually picked up (<4 m/s) from the N-NW. Followed DNSM star list; closed down at 14 UT. |

| | 363 | Shift started out with clear skies, winds from the NE at 2-3 m/s. Temp was 5 C with 3 % humidity. |
| | 364 | At midnight winds are around 6-8 m/s. DIMM seeing is not good. |
| | 365 | |
| | 366 | Locked onto Sirius at 0455. On to Spica at 1005 On to Arcturus at 1130. The telescope did not recognize this star as pre-programmed # 147. Wind is affecting data collection now. At 1345 to Vega. The scope was having tracking problems on Arcturus which was near zenith. Retried Arcturus but still having near zenith tracking problems. A quiet night otherwise. |

| | 375 | A start of shift, skies are clear, wind 4 to 6 m/s from the ENE. Humidity5%, temp 7. Winds decrease after midnight. Seeing 1" to 1.5" most of the night. Supposedly, seeing conditions (tonight and especially last night) were affected by a 100+ mph sub tropical jet in the free atmosphere. |
| | 376 | |
| | 377 | Locked onto Sirius at 0654. On to Procyon at 1010. PS1 has been doing non stop engineering from start of shift to 1028. |
| | 378 | Onto Arcturus at 1110. Arcturus lost track at zenith (its keyhole) so onto Antares at 1355 to end of tracking period at 1533. |

| | 387 | A variable weather night that started out with with mostly clear skies except for a little bit of cirrus. Wind were 3-6 m/s from the NE. The subtropical jet affects seeing again. |
| | 388 | Clouds thicken a lot around 0930. Humidity rises (70's), PS1 closes due to sudden drop of visibility. Clouds are nearby but lower in elevation. At 1050, a little fog blows through. Clouds, humidity and periods of fog end the night about an hour early as PS1 is closed again. |
| | 389 | |
| | 390 | A problem at start up. The telescopes 18v power supply was dead. It was replaced with another power supply from Haleakala's Amateur Astronomer's (Rob) surplus parts department. Locked onto Sirius at 0515. Lost track once due to clouds. To Procyon at midnight. Clear skies again. To Arcturus at 1110. Due to tracking problems with Arcturus at zenith, moved to Antares at 1345. Humidity and clouds again. PS1 closes. RoboDIMM closes at 1420. |
