Now runs the complete production pipeline without east-frame verification: find last full moon → fetch NASA Dial-a-Moon render → render_phase_closeup → test_last_full_moon_out.jpg with caption (phase, % lit, local time, NASA attribution). Also retains the sun_events_in_range() call as a regression check for the sunrise_sunset() bare-topos fix. https://claude.ai/code/session_01JieSeNQZ3X6fhsb11YyJrK

"""test_last_full_moon.py — produce a full-moon close-up for the most recent full moon.
|
|
|
|
Runs the same NASA Dial-a-Moon fetch + render_phase_closeup pipeline that
|
|
moon-phase-monthly.sh uses, but bypasses the east-frame witness step so it
|
|
works any time without needing captured frames.
|
|
|
|
Also exercises sun_events_in_range() (the sunrise/sunset almanac call that
|
|
requires a bare topos, not an earth+topos observer) as a regression check
|
|
for that fix.
|
|
|
|
Output: test_last_full_moon_out.jpg in the sky-cam directory.
|
|
|
|
Run from the sky-cam directory:
|
|
|
|
python3 test_last_full_moon.py
