City sky
Aurora: The Practical Verdict
Aurora, a small city in Illinois, experiences high light pollution influenced greatly by the nearby metropolis of Chicago, situated approximately 60 km east-north-east. The sky here struggles for visibility, with Bortle 8 classification indicating poor astronomy conditions and the Milky Way entirely obscured.
From Aurora's sky, visual observations should focus on targets like the Moon, planets, and bright double stars. Deep-sky objects and faint nebulae are effectively drowned out by the urban glow. Narrowband imaging can be attempted, but gradients remain significant limitations for broadband photography.
Improved skies are achievable with travel. About 45 km west-north-west lies a moderately better site. For substantial upgrades, you might consider areas roughly 110 km south-south-west, providing a Bortle 5 sky.
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
- Limited nearby upgrade
- 108 km SSW is the strongest nearby option but remains Bortle 5; the improvement is real but modest.
- Good dark window
- Aurora's longest dark windows fall in December and January, with the shortest nights around June and July. Plan deep-sky sessions around the autumn and winter months for the best combination of long nights and true astronomical darkness.
Frequently Asked Questions
Can you see the Milky Way from Aurora?
No. Aurora is a Bortle Class 8 sky with SQM 18.21, 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 Aurora?
Aurora is Bortle Class 8 (SQM 18.21), a poor city sky for astronomy.
Is Aurora good for stargazing?
Not for serious deep-sky observing. Aurora is a poor city sky where the Moon, planets, and a handful of bright targets are the realistic options from the city itself.
Is Aurora good for astrophotography?
Broadband deep-sky imaging is heavily compromised from Aurora and a Bortle 4 or darker site is strongly recommended. Even narrowband imaging is difficult from Aurora without careful processing.
What can you observe from Aurora?
Primary targets from Aurora 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 Aurora?
The closest meaningfully darker mapped site is 46 km WNW, about 46 km west north west of Aurora, reaching Bortle 6.
When is the sky darkest in Aurora?
The sky over Aurora is darkest around January, December.
Is light pollution in Aurora getting better or worse?
Long-term light pollution over Aurora has been broadly stable across the available measurements.
north - marginal
Soft skyglow visible on the north horizon. Mid-brightness stars survive at low elevation; the faintest do not.
north-north-east - marginal
Noticeable glow on the north-north-east horizon. Stars below about 20 degrees in this direction are dimmed.
north-east - marginal
Noticeable glow on the north-east horizon. Stars below about 20 degrees in this direction are dimmed.
east-north-east - marginal
Soft skyglow visible on the east-north-east horizon. Mid-brightness stars survive at low elevation; the faintest do not.
east - marginal
Noticeable glow on the east horizon. Stars below about 20 degrees in this direction are dimmed.
east-south-east - marginal
A diffuse glow sits on the east-south-east horizon. Faint objects below 20 degrees in this direction are compromised.
south-east - marginal
The south-east sky shows a clear glow near the ground. Above about 20 degrees the sky returns to workable.
south-south-east - marginal
The south-south-east lower sky is measurably brighter than the darker quarters. Limit faint work to above about 20 degrees here.
south - fair
The south sky is broadly dark with a small amount of glow at the horizon. Most objects in this direction are accessible.
south-south-west - fair
Faint glow on the south-south-west horizon. Most stars are visible to low elevation; only the faintest near the ground are affected.
south-west - fair
Light glow detectable on the south-west horizon. The effect fades quickly with elevation and does not affect overhead work.
west-south-west - fair
Faint glow on the west-south-west horizon. Most stars are visible to low elevation; only the faintest near the ground are affected.
west - fair
A trace of skyglow near the west horizon. Stars are clear throughout this direction except very close to the ground.
west-north-west - fair
The west-north-west sky is broadly dark with a small amount of glow at the horizon. Most objects in this direction are accessible.
north-west - fair
A trace of skyglow near the north-west horizon. Stars are clear throughout this direction except very close to the ground.
north-north-west - fair
A trace of skyglow near the north-north-west horizon. Stars are clear throughout this direction except very close to the ground.
zenith - marginal
The zenith is brighter than natural. The Milky Way cannot be seen and faint deep-sky objects are not accessible.
