If you already used our 2026 eclipse dates page, the workflow is the same: trust the catalog for when the geometry peaks, then check whether the body is above your horizon. Penumbral lunar eclipses punish guesswork because the shading is faint. Pair these UT instants with Moon phase around the full Moon nights and the transit calendar if you batch sky watching with planet tracking.

NASA's opening table on the 2027 page is the spine for this article. Detailed maps and Besselian elements live on linked pages; here we keep the summary the site already tabulates.
Eclipse types you will meet in 2027
Annular solar. The 6 February event has catalog magnitude 0.92811, central duration 07m51s, and path width 282 km at greatest eclipse. The greatest-eclipse point is 31.3°S, 48.5°W with the Sun 73° above the horizon in the catalog entry. The "ring of fire" label refers to that uncovered solar rim.
Total solar (2 August). Magnitude 1.07903, central duration 06m23s, path width 258 km. Greatest eclipse occurs at 25.5°N, 33.2°E with the Sun 82° high in the NASA line. This is the only total Sun eclipse of the year on the list.
Penumbral lunar (three events). The Moon skirts Earth's penumbra without fully entering the darker umbra (and for the July event the catalog lists a negative umbral magnitude, meaning no umbral contact). Observers often miss penumbral shading without instruments or careful photography. NASA still lists beginnings, greatest, and ends for each.
Understanding the type keeps expectations honest. A penumbral entry is not a failed total eclipse; it is a different geometry listed separately in the Five Millennium Canon of Lunar Eclipses.
February 2027: Sun then Moon
The annular solar eclipse peaks at 16:00 UT on 6 February per NASA. Saros 131 member 51 continues a long series described on NASA's Saros 131 page linked from the catalog.
Twelve days later, on 20 February, a penumbral lunar eclipse greatest is at 23:13 UT. Published phases:
| Phase | Time (UT) |
|---|---|
| Penumbral eclipse begins | 21:12 |
| Greatest eclipse | 23:13 |
| Penumbral eclipse ends | 01:13 (21 February) |
Penumbral magnitude is 0.9266 and umbral magnitude -0.0569 at greatest eclipse in the catalog. The Moon at greatest eclipse is near 10.0°N, 15.0°E at zenith in NASA's summary.
July 2027: a short penumbral
The 18 July penumbral eclipse is unusual because NASA's phase table spans only twelve minutes of UT clock time:
| Phase | Time (UT) |
|---|---|
| Penumbral eclipse begins | 15:57 |
| Greatest eclipse | 16:03 |
| Penumbral eclipse ends | 16:09 |
Magnitudes are 0.0014 penumbral and -1.0680 umbral at greatest eclipse, with the Moon near 22.0°S, 121.0°E at zenith. Treat this as an astronomical footnote unless you are deliberately logging faint penumbral events.
August 2027: total Sun and penumbral Moon
2 August total solar greatest eclipse is 10:07 UT (Saros 136). 17 August penumbral lunar greatest is 07:14 UT with penumbral magnitude 0.5456 and umbral magnitude -0.5254 in the catalog.
August lunar phases from NASA:
| Phase | Time (UT) |
|---|---|
| Penumbral eclipse begins | 05:24 |
| Greatest eclipse | 07:14 |
| Penumbral eclipse ends | 09:03 |
The Moon at greatest eclipse is near 12.0°S, 108.0°W in the yearly summary.
Converting UT without extra folklore
NASA tells readers to convert UT to local civil time using standard zone offsets. India Standard Time remains UTC+5:30. Example for 20 February greatest lunar eclipse at 23:13 UT:
- 23:13 + 5:30 = 04:43 IST on 21 February
The UT date was still 20 February, but IST crosses midnight. That split is why festival bloggers argue, and why eclipse bloggers should show the math.
For 2 August solar greatest at 10:07 UT, IST is 15:37 on the same date. Whether you see any phase still depends on latitude and the eclipse path from NASA maps, not on the conversion alone.
Visibility versus catalog truth
NASA's yearly pages are predictions from the Five Millennium Canons (Espenak and Meeus), not a per-city timetable. A penumbral lunar eclipse can be "real" in the catalog while your Moon is below the horizon. A total solar eclipse can be total only on the narrow path whose width NASA quotes in kilometers.
This article does not score cities for partial solar percentage because those numbers belong on NASA's eclipse-specific map pages, not invented here. Our gap versus repost sites is the same as for 2026: primary NASA UT, explicit type definitions, phase tables where NASA prints them, and links to live Inner Light moon phase and transit calendar.
August cluster and planning rhythm
Three of five 2027 eclipses sit in August (one solar, two lunar if you count the July penumbral in mid-summer). Travel planners sometimes anchor vacations on the 2 August total solar track using NASA's linked map resources. Eclipse chasers planning photography should separate the 17 August penumbral Moon from the total Sun event two weeks earlier; they share a season but not geometry.
Eclipses near full Moon traditions
Many Hindu calendars tie festivals to tithi counted from Sun-Moon elongation. Lunar eclipses occur at full Moon in astronomy, but the civil festival date in India still follows sunrise tithi rules described in NASA's calendar help. When a relative asks "is eclipse day Amavasya or Purnima," answer from panchang for their city, not from the eclipse headline alone.
Annular solar of 6 February: catalog numbers
NASA's annular entry adds detail beyond the summary table. At greatest eclipse the catalog lists Delta T 75.7 s, Gamma −0.29515, and Saros 131. The eclipse belongs to the series documented on NASA's Saros 131 page linked from the yearly summary. Observers along the narrow annular track may see the ring for the published 07m51s central duration; outside that path the Sun may show a partial phase only, or no eclipse if the Sun is down.
Use those map pages when a reader asks "can I see it from Madrid or Mumbai?" This article stops at catalog geometry so we do not imply visibility scores we did not measure.
Checklist before you share a screenshot
Confirm you copied UT versus local. Confirm whether the event is penumbral (no umbral entry) so friends do not expect a blood Moon. Link the NASA GSFC 2027 eclipse page instead of reposting unattributed tables. If you write about sky mood around eclipses, label astrology as tradition; NASA times stay factual.
