Mars - 20.10.2020 at 01.40 Kauhava Observation number 94342

Visibility IV / V

Jari Kankaanpää, Lakeuden Ursa

The wildest seeing variation throughout the opposition. From bad to excellent in just minutes. The soft and slow ripple of the atmosphere could stop abruptly for a moment and continue as a rapid vibration. Here is 15 percent of the 15,000 square set. I would use the definition of seeing good. Sometimes you have to try to manually pick up sharp squares and see what would be the end result.
