Sun - 13.7.2021 at 12.00 Kauniainen Observation number 99517

Visibility IV / V

Ben Kalland, Ursa (Helsinki)

Today, on the north edge of the Sun, slightly to the west, there were filaments so close to the edge that they continued as protuberances. You can see in the picture (maybe) that they are the same things.

Lunt 80 mm, Barlow, ASI 174.

Sama asia. Näitä joskus sanotaan filapromeiksi ja joskus näkee hienoja yksilöitä.
