Comet 13P/Olbers tonight
Is comet 13P/Olbers visible now?
Comet 13P/Olbers now has a magnitude of around 8 and is getting fainter by the day. It remains visible with powerful binoculars or a telescope under dark skies in both hemispheres, with the best view in the Northern Hemisphere. Also note that comets look fainter than stars with similar magnitudes, because the magnitude scale measures the total light spread out over the object, and in comets’ case this light is diffuse.
Where and when to see comet 13P/Olbers?
Comet 13P/Olbers is now in the constellation Coma Berenices and is visible on the western horizon for about 2 hours after sunset. Note that the exact position of the comet and the observation window depends strongly on your location.

13P/Olbers visibility forecast for 2024
Now let's take a look at the major points the comet will cross before it disappears.
- *August 30: mag ~9.0, passes the globular cluster M53;
- September 7: mag ~9.0, enters Bootes;
- September 10: mag ~10.0, enters Virgo;
- October 15: mag ~11.0, passes possibly naked-eye comet C/2023 A3 (Tsuchinshan-ATLAS), near the globular star cluster M5, but is poorly visible.
What is comet 13P/Olbers?
Comet 13P/Olbers is a Halley-type comet with an orbital period of 69 years. Like the other comets, it's an object composed of ice, rock, and dust. Because of this composition, comets are sometimes called "dirty snowballs" hurtling through space. That may sound unattractive, but it doesn't really make them look any worse to us on the Earth.

Comet 13P/Olbers name
The name of the comet contains data about where and when it was first seen:
- The letter P means the comet is periodic (a comet that takes less than 200 years to orbit the Sun);
- The number 13 means that comet Olbers was the 13th comet identified as periodic.
- Olbers indicates the name of the comet's discoverer, Heinrich Olbers.
Discovery and previous appearances
The comet was discovered in 1815 by the German astronomer Heinrich Wilhelm Matthäus Olbers, who is also famous for the formulation of the dark sky paradox. In the year of its discovery, 13P/Olbers reached a maximum magnitude of 5.
Then 13P/Olbers appeared in 1887, reaching magnitude 9 at its brightest. It went unnoticed for a while until another famous astronomer, William Brooks, accidentally found it on August 25.
In 1956, the comet returned once more. It reached a maximum magnitude of 6.5, while the tail reached a maximum length of one degree. The next time the comet will return to perihelion is on June 30, 2024, when it's expected to reach a magnitude of 6.5.

When is the next comet 2024?
When comet Olbers is gone, keep your eyes on the sky! A potential "comet of the century," C/2023 A3 (Tsuchinshan-ATLAS), is set to approach the Earth in October 2024. Optimistic predictions suggest it could shine as bright as magnitude 0. To learn more about this exciting space traveler, check out our dedicated article.
Both comets, Tsuchinshan-ATLAS and 13P/Olbers, can be tracked in the Sky Tonight app. You can follow their paths and set up alerts for their upcoming passages. So, let's enjoy the humble beauty of comet Olbers and hope for an even more spectacular display with Tsuchinshan-ATLAS!
