The Heliospheric Imager for the NASA STEREO Mission
Part of the SECCHI Consortium
Welcome
The Heliospheric Imager on the STEREO-Ahead
spacecraft recently witnessed the spectacular display as comet
Jovejoy plunged towards the Sun, emerging even brighter after being
heated. The sequence of images below show the comet approaching the
Sun (which is just outside the field of view on the right of the
frames) from the bottom left. The sequence goes from top left to
bottom right. The full movie can be
