In summary, the speaker is in Ottawa, Canada and noticing an unusually bright sky at almost 2 am. They are wondering why this is and someone suggests it could be due to a combination of heavy cloud cover and snow on the ground reflecting city lights. It is also mentioned that someone else had predicted the northern lights being visible further south, but it is unlikely that is the cause of the bright sky. The speaker also mentions light pollution being a factor.

Hello PF

I'm hoping someone can answer this for me.

I am in Ottawa, Canada and right now it is almost 2 am. I am about to go to sleep but can't help to notice why the sky is so unusually bright. It is a light peachy color. I can see the grass outside my house without any lights, it is that bright. I don't know why this is but I am curious. lol

Someone posted a thread sayings the northern lights would be visible much further south than normal (about a week ago maybe?) I wonder if that's what you're seeing. I don't think they're that bright though.

I think the cloud ceiling is either very low, or the clouds are unusually white. That way, more light from Ottawa's light bulbs would get reflected down to the ground.

Light pollution sucks, yo.

And it's back to normal tonight...

Did you move to Ottawa recently?

It's likely just a combination of heavy cloud cover and snow on the ground that helps reflect city lights (back and forth) and make for a bright night.

or maybe a light fog
 

Related to Why is the sky so bright here at night?

1. Why is the sky so bright here at night during a full moon?

During a full moon, the Earth is positioned between the sun and the moon, causing the moon to be fully illuminated by the sun's light. This reflected light from the moon can make the sky appear brighter at night.

2. Why does the sky appear brighter here at night than in other locations?

The brightness of the sky at night can vary due to a number of factors, such as the amount of light pollution in the area, the phase of the moon, and the position of the Earth in relation to the sun and moon. These factors can affect the amount of light that is able to reach our eyes and make the sky appear brighter or darker.

3. Does the weather affect the brightness of the sky at night?

Yes, the weather can have an impact on the brightness of the sky at night. Cloud cover can reflect light from cities or other sources, making the sky appear brighter. On clear nights, the lack of clouds can make the sky appear darker.

4. Why is the sky brighter here at night than it was in the past?

The brightness of the sky at night can change over time due to factors like urbanization and population growth. The increase in artificial light sources in cities can contribute to a brighter sky at night compared to previous years.

5. Is the brightness of the sky at night harmful to the environment?

The brightness of the sky at night, also known as light pollution, can have negative effects on the environment. It can disrupt the natural rhythms of wildlife and affect their behavior. It can also impact human health by disrupting sleep patterns and causing eye strain. Efforts to reduce light pollution can help mitigate these harmful effects.
