Sometimes it puts us completely in the shade (5,7)
I believe the answer is:
total eclipse
'shade' is the definition.
(I know that total eclipse is a type of solar eclipse)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for total eclipse that I've seen before include "Astronomical event" , "leaves you completely in the dark" , "Celestial phenomenon" , "complete blackout" , "Period of darkness" .)
