Eclipse 2027 in Mostaganem, Algeria
5m 02sof totality, from 09:52:06 to 09:57:09 local time
Mostaganem is inside the path of totality: the Moon covers the Sun completely and the corona appears — between second and third contact, and at no other point in the day.
Totality
5m 02s
Obscuration
100%
Magnitude
1.073
Sun altitude at max
44°
Magnitude is the fraction of the Sun's diameter the Moon covers; obscuration is the fraction of the Sun's area hidden. Near this path magnitude barely changes city to city, so the numbers that actually tell you what you'll see are duration (in the path) and obscuration (a partial).
Contact times in Mostaganem
Local times are Africa/Algiers (UTC+1 on 2 August 2027), converted from the app's fixed UTC instants with the IANA time zone database, release 2026c. The UTC instant is printed beside each one.
08:45:0807:45:08 UTC
Partial begins (C1)
The Moon first touches the Sun's edge. The partial phase starts — glasses on.
09:52:0608:52:06 UTC
Totality begins (C2)
Only inside the path of totality. The Moon fully covers the Sun; the corona appears.
09:54:3708:54:37 UTC
Maximum eclipse (Max)
Greatest coverage for your location — deepest partial, or the middle of totality.
09:57:0908:57:09 UTC
Totality ends (C3)
The Sun's disc begins to reappear. Protection back on immediately.
11:10:3410:10:34 UTC
Partial ends (C4)
The Moon leaves the Sun's disc. The eclipse is over.
The lit run is totality — 5m 02s of it, second contact to third.
These times are for Mostaganem. Eclipse 2027: Local Times counts them down wherever you actually stand on the day, with no signal needed, and wakes you at third contact so the glasses go back on in time.

Has the sky been clear?
In late July and early August, a given spot in Mostaganem has had the Sun in clear sky on about 8 days in 10 (80%), at the satellite pass nearest the eclipse, which comes about an hour and a half after it here. Good odds, not a certainty.
These are the only figures on this page that are not the app’s own. The times above are computed and can be checked to the second; this is measured, and it is history rather than a forecast. NASA’s MODIS instruments map cloud every day in 5 km squares, and the figure is the average share of clear sky over the land within about 12 km of Mostaganem, every day from 18 July to 17 August, 2001 to 2025 (775 days observed). That makes it the chance a spot there had the Sun in clear sky at that pass. On a partly cloudy day it counts the share of the sky that was clear, so it is the odds for one spot, not a count of clear days. It cannot tell one street from the next, and a satellite pass is not the minute of the eclipse.

When it is safe to look
Never look at the partially eclipsed Sun without certified solar-viewing filters — eclipse glasses that meet the ISO 12312-2 standard, or a safe solar telescope/camera filter. Ordinary sunglasses are not safe. Looking through binoculars, a telescope or a camera without a proper solar filter can cause permanent eye injury in an instant.
Only during totality — and only if you are inside the path of totality — is it safe to look with the naked eye, from C2 until C3. The moment the Sun's bright edge returns at C3, put protection back on.
Where these numbers come from
Contact times, magnitudes, obscurations and Sun altitudes are computed from the official NASA/GSFC Besselian elements for this eclipse (Fred Espenak) and cross-checked against independent published predictions; they agree to within a few seconds. Times shown are converted from fixed UTC instants into each city's local time. “Eclipse Predictions by Fred Espenak, NASA's GSFC.” This is a reference and planning tool — verify critical timings independently before travelling.
NASA/GSFC Besselian elements · Espenak · ΔT 71.7 s bridges UT and TDT (greatest eclipse 10:06:38 UT, not the 10:07:49 TDT some sources quote) · agrees with independent predictions within a few seconds.
Every figure on this page is lifted from Eclipse 2027: Local Times’s own shipped table by a script, and a test re-reads the app’s source to prove each one before this page deploys. Nothing here was written for the web.
