FL - Flare 2021-02-27T22:47:30 -> 2021-02-28T02:12:14 xcen, ycen = 838.8,378.8
Description: This was another episode of flaring activity and peacock tail in AR 12804 (as it approached the west limb with the solar rotation), especially in its trailing polarity (near the upper left of the movie). The peacock tail appeared as some episodic brightenings of an arcade of coronal loops on the lower-right edge of this trailing polarity. The brightenings appeared to propagate from lower loops to higher loops along the axis of the arcade (perpendicular to individual loops). The peacock tail occurred before and after the moderate flaring that peaked at about 00:11 UT.
