This contains the original pulsating auroral data used by the paper 'Pulsating Aurora Database and Automated Algorithm for Detecting them from Ground-Based Optical Imaging', which will appear in Frontiers in Astronomy and space sciences. This dataset contains a master catalog of auroral pulsation detections derived from ground-based all-sky imager observations, along with representative video and image files illustrating the underlying data products. The primary file, Pulsating_Aurora_event_list.txt, is a plain-text table summarizing automatically detected auroral pulsation events. For each event, the report lists the start and end times, corresponding image frame numbers, peak frame number, integrated intensity metrics (both median absolute deviation–normalized and raw), spatial region identifier, full width at half maximum (FWHM) duration in seconds, FWHM start and end frames, and the source TIFF file from which the event was extracted. The report was generated on 2026-01-07 using auroral image data from the groudn based auroral imager in Foker Flat, Alaska station. In addition to the report, the dataset includes: Three auroral video files (V_120813_03_39_53_13_9_1x.mp4, V_010714_16_02_23_19_8_1x.mp4, and V_010714_16_15_53_33_15_1x.mp4) that provide visual examples of auroral activity and pulsation behavior observed during selected intervals shown in Figure-1(a-b and e-f). One example TIFF image file (THA140107_15595711_16bit.tif) containing raw auroral image data representative of the inputs used in the pulsation detection analysis shown in Figure-1(a-b and e-f). The dataset is intended for use in space physics and auroral research, particularly studies of pulsating aurora and related magnetospheric processes.
