I have two questions:
How many hours of light and darkness are there in June at regions south of the Antartic Circle (dotted line in Southern Hemisphere)?
Six months later, when the earth is at the December position, is the situation in the Antartic the same or is it the reverse?
Isn't that winter in the Southern Hemisphere, when the night is 24 hours?
Six months after winter, ....the sun does not set. Very hard to get to sleep.
To determine the hours of light and darkness in June at regions south of the Antarctic Circle, you need to consider the specific location within the region. However, generally speaking, the Antarctic Circle marks the area where there is at least one day per year with 24 hours of continuous daylight (around the December solstice) and one day per year with 24 hours of continuous darkness (around the June solstice).
In June, which is winter in the Southern Hemisphere, it is indeed common for regions south of the Antarctic Circle to experience long periods of darkness. However, the exact duration of darkness may vary depending on the specific location within the region. Some areas might experience several weeks of continuous darkness, while others may have a few hours of twilight or scattered sunlight during the day.
Now, as for the situation in the Antarctic during December (six months after June), it varies because the Antarctic experiences a phenomenon called the "midnight sun." The midnight sun occurs when the sun remains visible at midnight or for a continuous 24-hour period. In December, regions south of the Antarctic Circle will experience this phenomenon, meaning they will have 24 hours of daylight.
So, to summarize:
- In June, regions south of the Antarctic Circle will generally have long periods of darkness, including the possibility of 24 hours of continuous darkness.
- In December, regions south of the Antarctic Circle will experience the midnight sun, with 24 hours of continuous daylight.
It's important to note that the exact specifics of light and darkness duration will depend on the location within the Antarctic region.
