Display the latest Synoptic (isobaric) weather chart from the Australian Bureau of Meteorology https://f3rr3t.com/bomSynoptic.git/atom?h=master 2026-06-09T03:04:04Z 2026-06-09T03:04:04Z St33v github@f3rr3t.com 2026-06-09T03:04:04Z urn:sha1:f058e83da43b0b661b45a7bd4c82b49c57e61d93 radarFetch.sh fetches BOM IDR713 transparencies (24h cache) and the last six 6-minute echo frames, composites them via cached lower/upper plates, and publishes an APNG loop to /srv/www/radar/. systemd: radar.{service,timer} on a 6-min cadence, with retry units mirroring the synoptic pattern. nginx: new radar.pestrel.com vhost (still commented in setup.sh until DNS propagation is confirmed). setup.sh provisions radar dirs, installs radar units, enables timer. deploy.sh accepts synoptic|radar arg. Parameterised on product code; adding another radar is a one-line config change. Spec: doc/bom-radar-spec.md. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
