Antisolar rays - 27.4.2017 at 19.00 Turku Observation number 63565

Visibility III / V

Paula Mattila, Ursa (Länsi-Suomi)

On the sea side, the sky was already cloudless, but over the inland there were plenty of clouds. Rays of cloud cover were visible again, but despite the clear rain, there was no rainbow, even though the sun was shining directly in the direction of the rain. However, a clear clearing was visible at the low point of the rainbow, can it appear almost colorless if the rain does not come but water as granules or slush?
