CIR impact. A nice auroral display. February 14-15, 2026.

During the CIR-impact on February 14-15, 2026, there was an instance of what looked like RAGDA to the south. A few images from local time 22:31 to 22:36 (or 21:31 to 21:36 UTC, if you wish). Following the RAGDA phenomenon a SAR-arc appeared, it lingered on, here photographed at local time 23:00 (UTC 22:00).

Details: Canon 650D, fisheye lens.
