| Description | Digital data of auroral keograms taken by the all-sky imager (made by Watec) with a filter of 557.7nm wavelength at Tjautjas, Sweden. This observation started in September, 2017. The original images were taken about every second. The north-south and east-west keograms are time-series of north-south and east-west cuts of auroral images and are used to see the north-south and east-west motions of aurora, respectively. |
