The color of the sunset has to do with the way light from the sun enters
the atmosphere. When the sun is overhead and the angle that the light
enters is small, the shortest wavelength light (violet and blue) are bent
slightly and are scattered by the air molecules and dust in the air to give
us a blue sky. If there is a lot of dust in the air, more light is
scattered making the sky appear less blue and sometimes even close to
white.
So where's all the dust coming from?
Spring planting.
Farm machinery is running day and night lately...
