Information about STEREO-A close approach to Earth, August 2023

Viewing Comet ISON's encounter with the Sun

When Comet ISON flies by the Sun on November 28, here are some of the ways to see the event as it happens, or soon after.

STEREO: There is a delay in the availability of the full resolution data from STEREO. However, the lower-resolution "beacon" data should be available in real-time, depending on the availability of the volunteer ground stations that bring us these data. Comet ISON should be easily visible in the COR1 and COR2 coronagraph data on our latest images page, as well as through the image search tool. In addition, the SECCHI team is processing special playback data to make Comet ISON images available more quickly than usual. These images will be available through their Javascript movie tool and their browse image gallery.

SOHO:Images of the comet in the Solar and Heliospheric Observatory LASCO C2 and C3 coronagraphs will appear on the regular SOHO real-time images page, and in the SOHO Movie Theater tool.

SDO: One of the very exciting possibilities of Comet ISON's encounter with the Sun is that we might see extreme-ultraviolet emission from it when it's closest to the Sun. To support this possibility, the Solar Dynamics Observatory is making available real-time images during the time of closest approach.

Here's more information about the STEREO plans for observing Comet ISON.
