| Marie leak checks the star cameras. Note that Mark has "fixed" the leak checker(at right) by adding several more hoses and fittings, and another pump. |
| Marco and Matt working on electronics. |
| The X-Y stage rastering. It's very slow. A complete scan takes a few hours. Fortunately this video does not. |
| Mark's additions to the leak checker. |
| Matt tricks out one of Paul Devlin's camera. |
| The FTS opened up to check alignment. The beam enters at top left, where the laser is, goes around a corner (via a mirror) and hits the beam splitter in the middle. After this part of the beam hits the bottom mirror, is reflected back and then out the left hand side, while the other part hits the mirror on the right, which moves, and then recombines with the first one to produce the interference pattern. |
| Another shot of the FTS. Note the red laser spot on the mirror at top, and also on the beam splitter below it. We use the FTS to measure the frequency response of the bolometers (ie. which colours they can see). |
| Bert the fork lift. It moves very slowly. |
| Mark finally diagnoses the leak in the OSC: a bad valve on the end of the test plumbing. Not a piece that will fly and also an easy fix. |
| Marie and Chris check to see if the FTS works. |
| The movable mirror inside the FTS moving. Enzo is checking to see if it is aligned. |
| The X-Y stage scanning and cordoned off with white tape to prevent people from accidentally stepping in the cryostat beam while we're taking measurements. |
| A strange email about how the USAP is going to save money by renaming "Regulated Medical Waste" "Sanitary Waste", and also introduce a new category "Sharps" (ie. razor blades, &c.). The most interesting part of the email is the writer's slogan. (Look at the bottom.) |
| BLAST's chin rewelded. Hopefully it will fit. |
| Attaching the FTS. |
| The Supergauge, monitoring the evacuation of the FTS chamber. |
| Violent shaking of the hose and Supergague as the FTS is pumped down. |

| Marie runs the FTS attached to the cryostat. |
| A closer view of the FTS attached to the cryostat. Note the intricate use of lab jacks and lead bricks to get the FTS to the right height. |
| Getting on Ivan at the end of the day. |
| They're starting to lay the fuel line out to Willy Field, in preparation for opening the air field next month. Note the Kiwi road crossing the line out on the ice. |
| Looking down on the ice shelf. The Willy Field road, which can be seen crossing along the edge of the land at bottom, disappears off to the left before reappearing at left and heading rightwards towards the LDB camp in the distance. Total distance on the ice: about 8 miles. |
| Another view of the new fuel line. |
| Don't be a Watt Hog. |
| The driers in the dorm come with a "moisture monitor". It's unclear to me what sort of information this monitor tells me and whether I should care. |
| Gaelen and Nick face off in air hockey. Gaelen was to retire undefeated. |
