Built for the moments around totality

Umbra Nomads is a field logging tool for solar eclipse observers.

Record the details that appear in the seconds around totality, from shadow bands and Baily's Beads to the diamond ring, corona activity, chromosphere observations, and temperature changes.

Keep each sighting in context

Create an observation with its eclipse phase, visibility, surface, location, conditions, tags, and field notes.

Photos can be attached to individual observations so the visual record stays with the sighting.

Follow the pulse of totality

Use the Totality Pulse timeline to record readings from the minute before totality through the minute after it.

Log timing offsets and field readings as the eclipse unfolds, then return to them later as part of the same observation record.

Prepare for the next event

The Eclipse Calendar keeps upcoming events and reminders together so future observations can be planned in advance.

Your observations stay yours
