I was the Project Scientist for the CDS instrument on SOHO during 2004-2007. This page has some links to CDS information that I prepared during this time. Please check the CDS homepage at RAL for more details about the instrument.


SOHO enters "keyhole" periods every 3 months where contacts are limited. A prescription for performing CDS planning during this period is available.

Following the successful launch of Hinode in 2006 September, a high priority for CDS is to obtain coordinated observations with the EIS instrument on Hinode. A guide to coordinating with EIS is available to aid CDS planners.
