The Solar and Heliospheric Observatory SOHO is now getting views of Comet ISON within its field. SOHO is a collaboration between the European Space Agency ESA and NASA. Launched in 1995, SOHO is positioned at the L1 Lagrangian point 1.5 million miles toward the Sun from Earth. The central view of the optics has a disc to block the bright sunlight and allow unobstructed views of the solar neighborhood. Revisit this page in a few hours. This image should be updated to the most recent and show the advance of the comet. ISON is now moving at tremendous speed toward perihelion Thursday midday. It will pass less than 1,000,000 miles from the surface of the Sun. If it survives, we will see it re-emerge in this imagery. See this post for a unique viewing opportunity by the SDO spacecraft during perihelion.

ISON will enter the higher resolution camera LASCO C2. The movie kiosk for C2 is here.
