Penumbral Lunar Eclipse of August 17, 2027
A subtle penumbral eclipse for all of North America and South America, most of Oceania and parts of Africa
On Tuesday, August 17, 2027 (UT) the Moon only enters Earth's faint outer shadow (penumbral magnitude 0.546). The dimming is far too slight to see with the eye; it is an eclipse on paper only. Anyone who can see the Moon sees the same eclipse at the same moment: the only questions are whether the Moon is above your horizon and what your clock says.
Computed on a 2° grid from the Moon's altitude (JPL DE440) at NASA's contact times. At the edges of the shaded area the Moon is low, rising or setting during the eclipse.

Watching it
We do not forecast the weather, and no one can this far ahead. Whether you see it will depend on the clouds on the day: check a local forecast a few days before and be ready to travel to a clearer sky. For long-term cloud statistics along eclipse paths, see the climatology by meteorologist Jay Anderson at eclipsophile.com.
Questions
Where is the penumbral lunar eclipse of August 17, 2027 visible?

Can I see it from the United States?
Yes: from 520 of our 520 US cities, 519 of them for the whole eclipse. US local dates may be the evening before the UT date.
Is it safe to watch?
Yes. A lunar eclipse is completely safe to watch with your eyes, binoculars or a telescope.
Will it be cloudy?
We do not forecast the weather. Check a local forecast a day or two before.
Eclipse predictions by Fred Espenak, NASA's GSFC: NASA Eclipse Web Site, Five Millennium Canon of Solar Eclipses and Catalog of Lunar Eclipses (Espenak & Meeus): Besselian elements, path of totality tables and lunar contact times. City times are computed by us from those Besselian elements with the standard method (Meeus, Elements of Solar Eclipses), using a current estimate of ΔT (Earth-rotation correction) instead of the Canon's older extrapolation; they agree with NASA's own calculator to 0.1 s and with an independent Skyfield/JPL DE440 computation to within 15 s. Times are for sea level and ignore the lunar limb profile (a few seconds near the path edges). Moon altitudes: Skyfield with JPL DE440, corrected for parallax. City coordinates: GeoNames (CC BY 4.0).
