Auroral Dunes. On 10 January 2026, around 19:55 local time (18:55 UTC) and for approximately 16 minutes, I observed a thin, diffuse green aurora showing clear horizontal ripple‑like structures. Thin clouds were present in the foreground and interfered at times, making interpretation more challenging both visually and photographically. Despite the cloud interference, the structures remained stable across several exposures — 20:01, 20:04, and 20:07 local time (19:01, 19:04, 19:07 UTC) — and the pattern is consistent with previously documented auroral dunes. Details: Canon 650D, 8mm fisheye-lens, Iso:1600, various exposure times.
