Abstract
We present 3.8 μm images of the Jovian satellite Io at an unprecedented ground-based resolution of 0 18. The images were obtained through two-dimensional speckle interferometry using the 6.86 m aperture of the Multiple Mirror Telescope in November 1989 and March 1990. To process the images we developed new speckle reduction techniques appropriate for objects with a size that is a significant fraction of the field of view. The images show three volcanic hotspots, including Pele, detected here for the first time since the Voyager 1 flyby in 1979.
