What does it mean when you see a yellow flashes in a night sky?
Most likely an aurora, depending upon your latitude.
Does latitude affect how dark it gets?
No, but latitude affects how long it stays dark. For example: At 90 degrees latitude, either north or south, the sun will set and stay down for 6 months, then will rise and stay up for the next 6 months. Yes, latitude indeed affects how dark it gets. For example north of the Arctic Circle there is no night or even twilight and latitudes slightly below the Arctic Circle experience a night-long twilight.
What is used to find latitude?
There are several ways in which you can determine your latitude. 1. Use a GPS unit. It will read out your latitude, longitude and precise time. 2. Look on a map; most navigational and topographic maps are scaled in latitude and longitude. 3. Radio navigation beacons like LORAN or R_NAV can give you your latitude. 4. At night, and in the northern hemisphere north of about 15N, you can (weather permitting) take a celestial observation of the north star Polaris, and the sextant reading is, with a half-degree or so, your latitude.
A star that is always visible in the night sky is called?
A circumpolar staris a star that, as viewed from a given latitude on Earth, never sets.
How far from zenith is the celestial equator when it crosses the celestial?
The angle between the celestial equator and your personal zenith is equal to the latitude of your location. (Whether it's north or south latitude doesn't matter, and neither does your longitude or the time of day or night where you are.)
What is used to allow an explorer to sail accurately during the day and the night?
An Astrolabe. It measures latitude by thehorizon.
What determines the length of night on earth?
Depends on where you are (latitude) and the time of year.
Which two control measures do you combine for night attacks?
LD and PD
How long are the night and day in the desert?
The length of the day or night in a desert depends upon the location (latitude) of the desert and the season of the year.
What is the length of night on the desert?
The length of day and night depend upon the season of the year and the latitude of the desert. Over a year it averages 12 hours of day and 12 hours of night.
Why is 57 degrees north considered a high latitude - is it just because 'twilight' lasts all night at that latitude in summer?
That's less than ten degrees from the Arctic Circle.

How many degrees below the horizon does the sun go at night on the winter solstice at latitude 57 degrees north?
On the winter solstice at a latitude of 57 degrees north, the sun will be about 33 degrees below the horizon at night. This is because the tilt of the Earth causes the sun to not rise above a certain angle during the winter months at this latitude.
How can i know what I am seeing in the night sky's above me at night?
You can search online for a chart that allows you to feed in your latitude and the date and that will tell you. Or like me, you can use a Planisphere for your latitude. Any good astronomy supply shop (including Amazon) will be able to help you with one).
What is hamsters characteristic?
Hamsters are usually very active at night and sleep during the day, little explorers, and they are shy! Hope I helped!
What is the length of night and day in the desert?
That depends upon the season of the year and the latitude. However, the hours of day and night in the desert are no different that those in other non desert areas at the same latitude and during the same season. Over a period of a year the average is 12 hours of day and 12 hours of night.
