A stable red arc was visible low in the southern sky from about 19:00 to 20:05. The arc showed no noticeable motion or auroral dynamics and remained uniform throughout the observation period. Its pure red emission, consistent with the 630.0 nm O I line, and its long‑lasting, featureless structure are characteristic of a Subauroral Red (SAR) arc. No green aurora or substorm activity was present in the same region at the time
