After the Perseids in August, the September sky also has a nice surprise in store for us! On Sunday, September 7, 2025, as soon as night falls, you’ll be able to observe a total lunar eclipse. This famous Blood Moon reveals a phenomenon in which our satellite is draped in a captivating reddish color, visible from Toulouse and a large part of France. This exceptional event, visible to the naked eye, will bring together astronomy enthusiasts!
Will the Blood Moon on September 7 really be red?
This famous phenomenon dubbed the “Blood Moon” intrigues many. But will we really be able to see a red moon in the Toulouse sky on September 7? The answer is yes, but with nuances. When the Moon passes into the Earth’s total shadow, it does not suddenly disappear. Sunlight – filtered and refracted by our atmosphere – breaks down and colors the lunar surface in tones ranging from brick-red to deep copper.
This hue also varies according to atmospheric pollution and local weather conditions. In this way, the Moon can oscillate between an intense dark red and a more subtle orange, sometimes even slightly coppery. This spectacular color is precisely what fascinates astronomy enthusiasts. So get ready to look up, because yes, the Blood Moon will offer you its fascinating red glow, even from Toulouse.
Lunar eclipse: a not-to-be-missed event for sky lovers
From 9.10pm on Sunday September 7, the Moon will slowly begin to darken. The total eclipse, when our satellite is entirely in the Earth’s shadow, will begin at around 10.10pm and last for around an hour. This precise moment when the Moon turns red, nicknamed the “Blood Moon”, is caused by the scattering of sunlight through the Earth’s atmosphere. This rare phenomenon is repeated every two years or so, but for many it retains a mysterious, almost mythical aura.
Good news, then! Anyone can observe this lunar eclipse. No need for sophisticated equipment: the spectacle is perfectly visible to the naked eye or with binoculars, from a clear spot. In Toulouse, why not take advantage of green spaces such as the Jardin des Plantes or the heights of Pech David to get the best view? The sky promises a beautiful show, and who knows, a few shooting stars along the way! Enough to make your back-to-school wishes come true.
