FMI emCCD ASCs: Images and animations

Sample images

Each all-sky image file name consists of the information on which station took the image, the date and time of the image, the filter selection and the exposure time. North is to the top and east to the right in the image. The last two time digits in the image file are for the milliseconds. Below are nearly simultaneous sample images on 5 Jan, 2008 at the blue wavelength from Sodankylä station where both the intensified imager and the emCCD camera are operated under the same dome.
