Total solar eclipse · 2 August 2027
Guides built on the same data as the app: the IGN verdict for every Spanish municipality, contact times to the second, and the AEMET cloud record. Written to be checked, not skimmed. The 12 August 2026 guides are kept below as a record of that day.
The band over the Strait, plotted to scale with the IGN durations. And why no map settles the Almería case, which misses at magnitude 1.00.
Only 102 of 7,528 municipalities are inside the band, all of them south of Sevilla. Ceuta gets 4 min 49 s, Tarifa 4 min 38 s, and Almería misses at magnitude 1.00.
Maximum falls between 10:46 and 10:59 local across fifteen cities, with the Sun 37 to 46 degrees up. Nothing is lost to sunset, unlike 2026.
Totality at the Strait on 2 August 2027, then the ring of fire over 3,078 municipalities at sunset on 26 January 2028. After that, nothing until 2030.
From 12 August 2026 — kept as a record of that eclipse
The umbra enters Galicia at 20:27 CEST and leaves over the Balearics six minutes later. The 22 provincial capitals inside the band, and why Madrid misses by the width of a suburb.
Contact times for A Coruña, Burgos, Madrid and Palma, and why in 6,060 of 7,531 municipalities the Sun sets before the eclipse finishes.
The surviving sliver of Sun is still around 400 times brighter than a full Moon. No corona, no darkness, and the glasses stay on.
ISO 12312-2 filters pass 0.00004 to 0.0032 percent of visible light. When they come off, how to spot untested glasses, and what to do without any.
Azimuth 283 degrees, west-northwest, with the Sun 2 to 12 degrees up. At 2 degrees a 20 metre building blocks it from 573 metres away.
AEMET gives the Cantabrian coast 30 to 50 percent clear sky at eclipse hour against 50 to 70 percent inland, plus what wildfire smoke does to a low Sun.
400 to 600mm frames the whole corona. Exposure bracketing, filter timing, and an argument for not photographing your first eclipse at all.
The app answers that one question for every Spanish municipality, with the IGN's own verdict, contact times to the second and a compass. The 2027 and 2028 eclipses are both bundled, and it works with no signal.
