TOTAL LUNAR ECLIPSE OF 2029 JUNE 26

The extremely deep total Lunar Eclipse of 2029 Jun 26 will be visible from the Americas, Europe, Africa and the Middle East with the Moon near the zenith as seen from Southeastern Brazil at greatest eclipse. During the event the Moon will probe the stratosphere over the Equator. A detailed eclipse figure made by Fred Espenak may be found here. The eclipse will be darker than expected for many observers, who have not yet realized that the primary mechanism that drives lunar eclipse brightness depends on how deeply the Moon goes into the umbra, rather than the absorption of sunlight by volcanic aerosols, that should be regarded as the second mechanism to be accounted for in case the event is preceded by any major stratospheric volcanic eruption. The author predicts that the visual magnitude of the Moon at mid-totality will be m=0.4±0.5 for an aerosol-free stratosphere. However, if major eruptions occur, additional darkening effects may have to be considered so that updated predictions for eclipse brightness will be posted here. The forementioned predicted magnitude for a clean atmosphere would correspond to a Danjon Number estimate of only L=1.4±0.2 (a dark red eclipse). Mid-totality Danjon Number evaluations as well as visual magnitude estimates of the Moon are welcome here. Download our Manual for further instructions.


Those willing to help determine the size of the umbra could use the following table, calculated by the author, as a guide for performing contact timings of limb and craters.

Also refer to the Manual on Lunar eclipse observation (Portuguese) or (English) for further instructions.
