August 2026 Skywatch: Total Solar Eclipse, Blue Moon, and More

August 2026 promises a spectacular display of celestial phenomena, including a total solar eclipse, a partial lunar eclipse, the Perseid meteor shower, and a Blue Moon. However, skywatchers in Indonesia will have a limited view of these cosmic events due to their geographic location and the timing of the occurrences.

Astronomer Avivah Yamani of the South Sky astronomy community in Bandung explained that while some of the month's most anticipated events will be outside Indonesia's viewing range, others can still be enjoyed from various parts of the country. The Total Solar Eclipse, expected around August 12-13, will trace a path across the Arctic, Greenland, Iceland, Spain, Portugal, and Russia, with partial visibility in parts of North America, Africa, and Europe. Unfortunately, Indonesia lies far outside this path, making it impossible to witness either the total or partial phases.

The Partial Lunar Eclipse on August 28 will grace the skies over the eastern Pacific, the Americas, Europe, and Africa. For Indonesia, however, this event coincides with daylight hours, rendering it unobservable. Similarly, the peak of the Perseid meteor shower, expected on the night of August 13 with up to 100 meteors per hour, will be missed. The meteors, originating from Comet Swift-Tuttle debris, appear to radiate from the Perseus constellation, which rises only after midnight in Indonesia, making the peak display effectively unobservable.

Despite these limitations, several celestial events remain accessible to Indonesian observers. On August 9, the star Elnath will disappear behind the Moon, an occultation visible from southern Papua, while elsewhere in Indonesia, the Moon will appear close to Beta Tauri. On August 16, Venus and the Moon will form a striking pair above the western horizon after sunset. Later, on August 21, the Moon will be seen near the bright star Antares in the southwestern sky. The month will also feature a New Moon on August 13 and a Full Moon on August 28, which, being the second Full Moon in August, is known as a Blue Moon, though it will not appear blue.

The next Total Solar Eclipse will not occur until two years from now.
