2022 September 11 Sun - A huge prominences on NE limb.

This huge prominences is observed in the morning (circa 03:05 UTC), but not visible in H-alpha in the afternoon (circa 05:20 UTC). I am not sure if this prominences is observable only in Ca-K, or if the prominences has faded away in just over 2 hours.

Sunspot count: group=9, sunspot=67, R=157

For Ca-K images:
Telescope: Maxvision APO refractor, ED Triplet
Camera : ASI1600MM Pro, not cooled
focal length : 700 mm f/7
Filter: Lunt Ca-K Module B1200

For H-alpha images:
Telescope: Lunt LS100Tha with B1200 blocking filter + 2X barlow
Camera : ASI1600MM Pro, not cooled.

approximately north is up, east to the left.
