Yes, but marginally: with 100% obscuration, the topographic horizon from Onda is very close to the Sun's altitude at the end.
Maximum occurs at 20:32 local time (18:32 UTC) in Onda.
Look WNW (azimuth 285°); the Sun will be 5° above the horizon at maximum from Onda.
Totality lasts 1 min 35 s in Onda (C2 to C3).
Onda will see totality (C2-C3) very close to the western horizon. The partial end (C4) falls below the horizon: you need a clear western view for an epic experience.
Yes, you need ISO 12312-2 certified eclipse glasses during every partial phase. Regular sunglasses do NOT protect. Glasses can only be removed during the totality phase (when the Sun is fully covered); never during annular or partial eclipses. Pages flagged "visible" assume a clear horizon, not a viewing recommendation.
For the August 12 eclipse. Recommended stay: Aug 10–14, 2026.
