The SOHO Scientific Instruments

Data accessAlthough it was not envisioned in 1988, the World-Wide Web has allowed the SOHO data to be widely and nearly

instantaneously distributed to the internationalscientificcommunity, students, and thegeneralpublic."Outreach"hasbeen
raised to a newlevel.By typinghttp://sohowww.nascom.nasa.gov/anyone anywhereon the Internetcan getimmediate

access to the daily SOHO data base as well as to a wealth of information, which includes current images, solar movies, observ-

ing plans,details of the mission, and descriptionsof the instruments.Web tools allow anyone accessto the record of SOHO

observations and the means to request scientific data. The SOHO Data Archive is operational at GSFC and copies are in various

stagesof developmentin Europe atInstitut d'Astrophysique Spatiale (IAS),Orsay (France),Rutherford-Appleton Laboratory
