2023 June 02 Sun - Huge prominences on SWW solar limb. Part A - in Ca-K

These images taken from 02:20 UTC to 02:28 UTC in Ca-K. Plasma flow is observed.
Part B will show the prominences in H-alpha, about 1 hour after the Ca-K images.
Thus we can consider the 2 sets of images as a sequence, despite that fact that they are taken in different wavelengths.

Sunspot count: group=9, sunspot=51, R=141
Telescope: Baader Triband C9.25 solar telescope, 235 mm f/10 with
Camera : ASI1600MM Pro, cooled to -4.0C.
Filters: Lunt Ca-K module B1200

approximately north is up, east to the left.
