The Observatory places masts, radiometers and acoustic arrays on buildings and film sets, reads them every second for weeks, and returns a log your engineers and your cinematographer can act on. The field behind this page is a live model of tonight. Scroll, and the night advances.

02  /  ONE CASE

‘The Long Shore’ — night exterior, Sognefjord. Eleven nights. This is night seven.

A feature shot on a jetty in October. Mast W3 on the jetty, the array on the ridge, the radiometer on the crane. We logged the night; the crew planned by it. The field replays it as you scroll.

GAFFER

Blue hour called for 04:52 at midnight. Rigged by 04:00.

1ST AD

Wind alarm at 20 kn; rain hold and restart from the log, not the sky.

  1. 22:00

    Crew call. 1008 hPa and falling; the log already says the front lands before one.

  2. 22:40

    Camera rolls. 9 kn from 214°, LAeq 46 dB — the array puts the generator at 118°; it moves.

  3. 23:50

    Front arrives. 22 kn gusting 31. Cranes lowered at the wind alarm, not at the guess.

  4. 01:05

    Rain hold. 58 dB of rain on the jetty; the set is struck under cover.

  5. 02:50

    Pressure bottoms at 991 hPa. Wind veers north-west; the clearing is on the log two hours before the sky.

  6. 04:20

    Clearing. Second unit resumes on the ridge.

  7. 04:52

    Blue hour: 14 lx, 9 800 K. The gaffer rigged for this at midnight. Last take.

  8. 05:40

    Wrap. Night log signed and delivered before breakfast.

Tonight’s conditions, from the field you scrolled through.

This panel is read from the model behind the page at the moment you arrived here — the hour, the wind, the pressure under the pointer. Take it with you, or ask for a station on your site.
