The Moon appeared red and became much darker in the late-August night sky.
This phenomenon was a partial lunar eclipse, but at its maximum, it looked close to a total lunar eclipse.
Here is what to know about why the Moon looked red and what to keep in mind when viewing it with the naked eye.
3-Line Summary
1. The partial lunar eclipse was not a total lunar eclipse
2. About 93% of the Moon was obscured at maximum
3. A lunar eclipse is not harmful to the eyes even when viewed with the naked eye
It Was a Partial Lunar Eclipse in Which Up to 93.2% Was Obscured
According to a report by Infobae (an Argentine media outlet), during the partial lunar eclipse that continued from August 27 to 28, 93.2% of the Moon’s surface entered Earth’s umbra at maximum. Although it was not a total lunar eclipse, in which the entire Moon is immersed in shadow, only a very small portion remained in direct sunlight, so it could appear as though almost the entire Moon were covered.
Telemundo Miami (a regional broadcaster in Florida, U.S.) likewise reported that about 93% of the Moon was obscured in Miami, making it look similar to a total lunar eclipse at times. The observation locations mentioned in that report were Miami-Dade, Broward, and Palm Beach.
A lunar eclipse begins when the Moon first enters the penumbra, the outer region of Earth’s shadow. The change at this stage can be subtle to the naked eye. Then, during the partial phase, when the darker umbra begins covering the lunar disk, the dark shadow becomes distinct. Even if the Moon appeared almost to disappear in photographs, when determining the type of eclipse, the percentage obscured should be considered before its red color.
The Red Glow Was Not a Change in the Moon’s Own Color
The reason the Moon appeared red, copper-colored, and sometimes orange at maximum was Earth’s atmosphere. Telemundo Miami explained that as sunlight passes through Earth’s atmosphere, blue-spectrum light is scattered more easily, while more red- and orange-spectrum light continues on to the Moon’s surface.
Thus, even inside Earth’s deep shadow, the Moon may not appear completely black. Infobae reported that this phenomenon is also popularly called a “blood moon.” However, the name does not mean that the Moon actually turned to blood; it is better understood as a term referring to the colors that may appear during a lunar eclipse.
This lunar eclipse was not an event limited to one specific city. Infobae reported that it could be observed in the Americas, Europe, and Africa, while Telemundo Miami separately reported on viewing conditions in southern Florida, U.S. Because the Moon’s altitude in the sky and cloud conditions vary by location, the same phenomenon may be experienced differently.
No Special Filter Was Needed for Naked-Eye Viewing
Unlike a solar eclipse, a lunar eclipse is not harmful to the eyes when viewed with the naked eye, Infobae reported. Special protective glasses or equipment were not required. Binoculars or a basic telescope can help viewers see lunar craters and color tones in greater detail, but they are not required for observation.
For better viewing, a location with little strong artificial lighting, such as streetlights or billboards, and an unobstructed view is preferable. The maximum time cited for Argentina in the report was 1:14 a.m., while the maximum time given in the Miami report was 12:12 a.m. These times are local to their respective locations and should not be applied directly to other regions.
The key point of this event is that it was classified as a partial lunar eclipse, rather than simply that it looked red. A red Moon can result from sunlight passing through the atmosphere. When viewing the next lunar eclipse, it is better to check the local time, sky conditions, and how much of the Moon is obscured together, rather than rely on a single photograph.
A Guide for Reading the Next Announcement
It is difficult to draw a conclusion about eclipse hoy-related news from a single number or sentence alone. The meaning becomes clearer if you distinguish who made the announcement, whether it describes something already implemented or a plan for the future, and whether the target and timing are specified concretely.
Even within the same material, an explanation of necessity, discussion, an implementation plan, and actual implementation may represent different stages. Even if an announcement appears large in scope, you should also check what it covers and what procedures remain so that you do not exaggerate or understate the current situation.
In the next update, compare whether the new announcement repeats existing content or whether the target, schedule, or implementation status has actually changed. Reviewing the related reports below as well can help identify differences in wording that are easy to miss from the headlines alone.
