Sun - 19.5.2017 at 18.20 Espoo Observation number 64044

Visibility IV / V

Tommi Ropponen, Ursa (Etelä-Suomi)

There were 2 spots in the sun, so something small is happening after all. At the time of filming, a thin cloud of gauze was constantly sailing past the sun, so transparency was not best. Seeing, on the other hand, seemed reasonable. A few protests visible here and there, but no big flare.

Warm enough when shooting, which is nice after the winter frosts. Again, there seemed to be interested enough, so the screen of the laptop became a play on the surface of the sun for a few passers-by.
