The Moon, slightly too small to cover the Sun, will leave a ring of it for 5 min 27 s, from 18:49:58 to 18:55:26 (local time in Porto-Novo). At maximum, at 18:52:42, the Sun will stand 1° above the horizon, towards the west-south-west.

|---|---|---|---|
| First contact — the Moon touches the Sun | 17:43:41 | 16:43:41 | 17° |
| Annularity begins | 18:49:58 | 17:49:58 | 2° |
| Maximum | 18:52:42 | 17:52:42 | 1° |
| Annularity ends | 18:55:26 | 17:55:26 | 0° |
| Last contact — the Moon leaves the Sun | 19:54:09 | 18:54:09 | below the horizon |
Mind the altitude of the Sun: it will stand only 1° above the horizon, towards the west-south-west. You need a completely clear view that way — a hill, a building or a line of trees is enough to hide everything.
That day the Moon is slightly too far from the Earth to cover the whole Sun: at maximum it leaves a bright ring. The sky darkens noticeably but never becomes night, and eye protection remains necessary from start to finish, ring included.
The annular phase lasts 5 min 27 s, from 18:49:58 to 18:55:26; the partial phase ends at 19:54:09.
Times and geometry computed by Novilune for the point 6.3677° N, 2.4253° E (altitude 6 m), from the Jet Propulsion Laboratory's DE441 ephemeris, with ΔT = 69.2 s. The uncertainty on ΔT (± 5 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 Porto-Novo (UT +01:00).
Novilune draws this eclipse as it will be seen from Cotonou — 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.
