This is subset of the data from MIRACLE emCCD all-sky imager at Abisko Scientific Research Station. The subset includes raw images of aurora emissions taken 557,7nm (G) in regular synoptic observation routine of MIRACLE emCCD cameras during the pulsating aurora event observed 15 Mar 2018 01-02UT. The data set is used in the paper "Detection of Pulsating Aurora from GNSS Total Electron Content" by J. Pérez-Coll Jiménez et al. submitted t Geophysical Research Letters. The raw images are 16-bit, 512x512px stored in PNG format and the metadata of the imager settings are written in EXIF comment field of the each image. Image filename includes station code, date, starting time of exposure, used filter and exposure time. The datalogger PC has own GPS stratus0 NTP source to keep the computer in time. Image sequences are started at given seconds. The delay between images in sequence is depending on the exposure time and delay of the filter rotation. The 1 minute regular MIRACLE sequence during the event from 00s to 55s was SEQ_00=GB, SEQ_05=BG, SEQ_10=GC, SEQ_15=RH, SEQ_20=GB, SEQ_25=BG, SEQ_30=GS, SEQ_35=RW, SEQ_40=GB, SEQ_45=BG, SEQ_50=GD, SEQ_55=BG, where G is the 557nm filter used in this study. The emCCD imager at the Abisko Scientific Research Station of Swedish Polar Research Secretariat is owned and operated by Sodankylä Geophysical Observatory, University of Oulu.
