Merapi Volcano, Indonesia was imaged on two different opportunities recently by the ASTER spaceborne instrument following a special observation request. A daytime image (15m/pixel) was collected on 26 April 2006 at 03:05 UTC and a night time thermal infrared (TIR) image (90m/pixel) was collected on 28 April 2006 at 15:10 UTC.

The daytime image shows a minor plume, however most of the summit is obscured by a small cloud.  The nighttime image shows a clear summit with obvious (albeit low-grade) thermally-elevated pixels (max = 25.9 C). These pixels are clustered near the summit with a lesser anomaly (max = 15.5 C) approximately 650m to the southwest and down slope from the summit.
