Rainbow

A natural phenomenon

October experienced a mix of sunny and rainy days. Several rainbows appeared during the month. To see a rainbow, the sun needs to be positioned behind a person with water droplets (rain, mist, etc.) in front. Rainbows are generally seen as incomplete circles from the ground because the horizon blocks the lower half from view. However, viewed from an aeroplane a complete circle may become visible. A rainbow does not occupy a specific location in the sky; it is an optical illusion which can never be approached or touched. Since it depends on individual's perspective, no two people see exactly the same rainbow.
