At 9:35 a.m. EDT (1335 UTC) on Sept. 13, the MODIS instrument aboard NASA's Aqua satellite looked at Typhoon Mangkhut in infrared light as it was approaching the Philippines. MODIS saw that Mangkhut has a 27 nautical-mile-wide eye.

MODIS also found coldest cloud top temperatures around the eye, as cold as or colder than minus 80 degrees Fahrenheit (F)/minus 112 degrees Celsius (C). Surrounding the eye were thick rings of powerful storms with cloud tops as cold as or colder than minus 70F (minus 56.6C).
