Novilune — solar eclipses: history, astronomy, observing
Solar eclipse · Wednesday 26 January 2028 · Cayenne, French Guiana

Partial eclipse in Cayenne, 26 January 2028

The Moon will cover at most 84% of the solar disc (magnitude 0.906), at 12:09:43 (local time in Cayenne). The Sun will then stand 65° above the horizon, towards the south-south-east. There is no totality here.

The path near you
Cayenne lies outside the path of annularity. Its edge runs 69 km towards the south-east — that is where you have to stand to see the ring close.

For about two hours the Moon eats into the solar disc and then releases it. To the naked eye the drop in light is hardly noticeable until three quarters of the Sun are covered; here, at maximum, 84% of the disc will be hidden. The drop in light will be noticeable to anyone paying attention, no more than that.

To see totality you must be inside the path of totality — the eclipse map and the list of cities on the eclipse page show where it runs.

In Cayenne, on 26 January 2028, there is no moment at which the Sun can be looked at without protection: eclipse glasses (ISO 12312-2) or projection onto a sheet of paper, from first to last contact.

Where these figures come from

Times and geometry computed by Novilune for the point 4.9372° N, 52.3259° W (altitude 7 m), from the Jet Propulsion Laboratory's DE441 ephemeris, with ΔT = 69.3 s. The uncertainty on ΔT (± 6 s) shifts all the times together by a few seconds at most; atmospheric refraction is not applied (it does not change the contact times appreciably at this altitude of the Sun).

Times are given in local time in Cayenne (UT -03:00).

In the app

Novilune draws this eclipse as it will be seen from Cayenne — the two discs at maximum, the Moon's path, the map of the path of totality — and does the same for every new moon from 2000 BC to AD 3000, for any place on Earth, offline.
