# rsutcliffe/nightwatch

> Silent macOS menu-bar app that tells you when tonight is clear enough for telescope imaging and what to point at. Works with any telescope.

- Magnitude: 3.2 out of 10 — Steady
- Stars: 50 total · +36 stars measured 2026-10-05, 19:03–21:24 UTC, ≈ 40 by evening
- Star trust: star growth looks organic
- Category: Science & research · Language: Swift · License: MIT · Created: 2026-09-25 · Last push: 2026-10-05
- GitHub: https://github.com/rsutcliffe/nightwatch · Homepage: https://delphi-dolphin.com/nightwatch · Page: https://gitnova.dev/en/r/rsutcliffe/nightwatch

## Useful for

- Check the clear-sky forecast for the next ten nights and pick the best one for imaging
- Plan a target's shoot with the right filter, exposure and frame count for the clear window
- Find darker sites nearby and compare them with your current location

## Why it’s here

- Star-counter measurements on 2026-10-05 (UTC), 19:03–21:24: 14 → 50 stars (+36). This is the change over that interval.
- Estimated end-of-day forecast: about +40 stars, using observed gains and the previous day.
- The repository is 10 days old and already has 50 stars. With less than two weeks of history, there's no usual pace to compare the spike against yet.

## Star trust

Star growth looks organic.

Star-trust labels are heuristics based on the repository’s behavior, not a check of every stargazer.

## Numbers

- Forks: 1
- Issues and pull requests: 145
- Watchers: 0
- Average over the last week: 6 per day
- Usual pace: too little history (under two weeks)
- Stars in the last hour (measured): 12
- Latest release: v1.4.0 (2026-10-05)

## Stars per day, last 16 days (oldest → newest, today is partial)

2026-09-20 … 2026-10-05: 0, 0, 0, 0, 0, 0, 0, 0, 2, 0, 0, 0, 0, 0, 0, 36

Magnitude (0–10) measures how fast and how unusually interest in a repository is growing right now. It is not a quality score.
Days are UTC. “So far today” is a fact; “expected by the end of the day” is a forecast.
Summaries and use cases are written by an LLM (DeepSeek V4.1 Flash) from the README and may be inaccurate: verify specific claims (benchmarks, speed, hardware) in the repository itself.
