City sky
Nairobi: The Practical Verdict
Nairobi, the bustling capital of Kenya, is cloaked under a significant urban light dome. Astronomy quality here is classified as a poor city sky, with extreme challenges faced by stargazers in capturing even moderately detailed cosmic vistas. The predominant limiting factor is the high level of light pollution.
The Milky Way is invisible against the urban brightness, making celestial features like galaxies and faint nebulae nearly impossible to spot. Observations are restricted to brighter celestial objects such as the Moon, planets, and some bright stars. For imaging purposes, narrowband techniques might still yield results, particularly for solar system events and double stars.
To truly indulge in deep-sky observing, a trip to Kcckambimbao, Nakuru, about 80 km north-west, is highly recommended. This location offers significantly darker skies, conducive for a more enriching astronomical experience.
At a Glance
- Overall
- Poor city sky - This is a poor city sky. The Milky Way is not visible and most deep-sky observing is unrealistic from the location itself.
- Milky Way
- Not visible - The Milky Way is erased by the bright urban sky background.
- Best targets from here
- Moon, planets, bright stars, double stars, solar system events, narrowband imaging only with care
- Do not prioritise
- visual deep-sky observing, broadband galaxies, reflection nebulae, widefield Milky Way
- Best nearby upgrade
- Kcckambimbao, Nakuru sits about 81 km north west and reaches Bortle 3, roughly 10x darker.
- Good dark window
- Nairobi retains astronomical darkness throughout the year, so seasonality is less extreme than at higher latitudes. The main limitation is light pollution, not the length of the dark window.
Frequently Asked Questions
Can you see the Milky Way from Nairobi?
No. Nairobi is a Bortle Class 8 sky with SQM 18.75, so the Milky Way is not visible from the city. For Milky Way photography, look for a Bortle 4 or darker site.
What Bortle class is Nairobi?
Nairobi is Bortle Class 8 (SQM 18.75), a poor city sky for astronomy.
Is Nairobi good for stargazing?
Not for serious deep-sky observing. Nairobi is a poor city sky where the Moon, planets, and a handful of bright targets are the realistic options from the city itself.
Is Nairobi good for astrophotography?
Broadband deep-sky imaging is heavily compromised from Nairobi and a Bortle 4 or darker site is strongly recommended. Even narrowband imaging is difficult from Nairobi without careful processing.
What can you observe from Nairobi?
Primary targets from Nairobi include Moon, planets, bright stars, double stars, solar system events. Targets such as visual deep-sky observing, broadband galaxies, reflection nebulae are not realistic from this sky.
Where are darker skies near Nairobi?
The closest meaningfully darker mapped site is Limuru East ward, Kiambu, about 26 km north north west of Nairobi, reaching Bortle 6.
When is the sky darkest in Nairobi?
The sky over Nairobi is darkest around April, September.
Is light pollution in Nairobi getting better or worse?
Long-term light pollution over Nairobi has been broadly stable across the available measurements.
north - good
Dark sky in the north direction with no obvious skyglow. Suitable for faint-object work at low elevation.
north-north-east - fair
The north-north-east sky is broadly dark with a small amount of glow at the horizon. Most objects in this direction are accessible.
north-east - fair
A trace of skyglow near the north-east horizon. Stars are clear throughout this direction except very close to the ground.
east-north-east - fair
Faint glow on the east-north-east horizon. Most stars are visible to low elevation; only the faintest near the ground are affected.
east - fair
A faint diffuse glow on the east horizon. Stars are visible to low elevation, with minor losses near the ground.
east-south-east - fair
A faint diffuse glow on the east-south-east horizon. Stars are visible to low elevation, with minor losses near the ground.
south-east - fair
Light glow detectable on the south-east horizon. The effect fades quickly with elevation and does not affect overhead work.
south-south-east - good
The south-south-east sky is dark to the horizon. Faint targets are accessible at all elevations here.
south - good
No noticeable light pollution to the south. The sky in this direction is dark to the horizon.
south-south-west - good
Dark sky in the south-south-west direction with no obvious skyglow. Suitable for faint-object work at low elevation.
south-west - good
The south-west horizon is dark. Faint stars are visible close to the ground.
west-south-west - good
Dark horizon to the west-south-west. Faint stars and extended objects in this direction behave much as they do overhead.
west - good
Dark horizon to the west. Faint stars and extended objects in this direction behave much as they do overhead.
west-north-west - good
No noticeable light pollution to the west-north-west. The sky in this direction is dark to the horizon.
north-west - good
Dark sky in the north-west direction with no obvious skyglow. Suitable for faint-object work at low elevation.
north-north-west - good
No noticeable light pollution to the north-north-west. The sky in this direction is dark to the horizon.
zenith - marginal
The zenith is brighter than natural. The Milky Way cannot be seen and faint deep-sky objects are not accessible.
