As a traditional optical observation system, the aurora imager mainly comprises outdoor optical lenses, indoor optical components and main control cabinet, sampling computer, connection box and A/D box. The aurora imager utilizes two-dimensional imaging technology to record auroral activities of multiple auroral spectral lines within the horizontal field of view.

This dataset comprises observation data collected by the aurora imager at the Chinese Arctic Yellow River Station during the 2022 Chinese Arctic Scientific Expedition. Recording auroral variations across different bands is of critical importance for comprehending changes in the polar space environment.

1. Measuring Instruments
- Instrument Name: Aurora Imager
- Instrument Model: ASI
- Calibration Method: Intensity extraction is performed using optical calibration methods.

2. Observation Methods and Acquired Observation Data
Auroral activity data across different local bands are collected at a sampling interval of 10 seconds. Relevant auroral information can be derived through post-processing procedures.

3. Observation Area
Above the Chinese Arctic Yellow River Station.
