11 UTC loops of 2021 (so far): durations of 9<\/a> and 18 seconds<\/a>. Also as an animated gif<\/a>. These posted GOES-16 Full Disk imagery are only showing a small number of the pixels, for a fuller resolution image at one time (20-June-2021<\/a>).<\/p>\n\n\n\n

An interactive web page<\/a> with almost a years worth of GOES ABI Full Disk visible images at 11 UTC. The beginning date is the (northern hemisphere) summer solstice in 2021 and the end date is the winter solstice in 2021. A user can play the animation, as well as annotate the images. For example, draw lines along the terminator<\/a> for different times of the year. One example might be to compare a solstice to an equinox. Can you estimate the day of the summery equinox? H\/T Tom Whittaker, SSEC, for the webapp<\/a>. Note that the app allows one to save an mp4 animation. <\/p>\n\n\n\n
