The Moon, slightly too small to cover the Sun, will leave a ring of it for 4 min 04 s, from 12:15:24 to 12:19:28 (local time in Buenos Aires). At maximum, at 12:17:26, the Sun will stand 63° above the horizon, towards the north-east.

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 4 min 04 s, from 12:15:24 to 12:19:28; the partial phase ends at 14:00:18.
Times and geometry computed by Novilune for the point 38.7177° S, 62.2655° W (altitude 23 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 Buenos Aires (UT -03:00).
Novilune draws this eclipse as it will be seen from Bahía Blanca — 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.
