Hi eneryone,
I need some help with this question:
"The period when the altitude of the Sun lies beween 0◦ and −6◦ is defined as ‘civil twilight’.
Calculate at what latitude it is still just twilight at midnight on the summer solstice."
Is it to do with the Earth's tilt of approximately 23◦ and the tropic of cancer (for N hemisphere), giving me an answer of about 23.5 ◦?
Thanks.![]()
