Did you time the eclipse?

On August 12, 2026, many people timed eclipse contacts — on video, on a phone, or by eye. Every real instant you share is compared against our model, never blindly validated by it: the model and your observation are two different ways of measuring the same thing, each with its own margin of error.

This material fades with every passing week — videos get deleted, memories blur. If you have something to share, do it now.

Where you observed from

Address

Latitude

Longitude

How did you get this position?

Altitude (m, optional)

Which contact did you time?

Contact time (UTC)

In UTC, not your local time. On Aug 12, 2026 totality over Spain fell around 18-19h UTC (20-21h local).

How did you measure the instant?

How would you describe your measurement chain?

Pick whatever best describes how you got the time — it doesn't need to be perfect. Every class is welcome, even "by hand".

Your estimated margin of error (seconds)

Not sure what to put? Use the typical ceiling for your class: O-A ≈ 0.05s · O-B ≈ 0.3s · O-C ≈ 1s. A smaller margin needs to be backed by your clock's real uncertainty below.

Technical details (optional) — help justify a smaller margin of error

None of this is required. The more you fill in, the more defensible a small margin of error is — but an observation with none of it is still welcome.

Clock source

How it was synchronized

Real synchronization uncertainty (seconds)

Video frame rate

How the frame's instant was read

Exposure duration (ms)

What did you count as the exact instant?

Equipment used

Link to your evidence (public video, thread, etc.)

Link to your video or photo (optional)

Additional notes

You may publish my exact location (otherwise it's rounded to ~1 km in any public report)
