INTERNATIONAL HELIOPHYSICAL
YEAR (IHY) CONTRIBUTIONS TO
SPACE WEATHER RESEARCH
Heliophysical: A broadening of the concept "geophysical," extending the connections from
the Earth to the Sun & interplanetary space. On the 50th anniversary of the International
Geophysical Year, the 2007 IHY activities will build on the success of IGY 1957 by
continuing its legacy of system-wide studies of the extended heliophysical domain

Objectives
•
•
•
•
•
Develop the basic science of heliophysics through crossdisciplinary studies of universal processes.
Promote research on the Sun-heliosphere system outward to
the local interstellar medium - the new frontier.
Foster international scientific cooperation in the study of
heliophysical phenomena now and in the future.
Preserve the history and legacy of the IGY on its 50th
Anniversary.
Communicate unique IHY results to the scientific community
and the general public.

Whole Heliospheric Interval
(WHI)
Primary Goals:
• Characterize the 3-D solar minimum
heliosphere
• Trace the effects of solar structure and
activity through the solar wind to the Earth
and other planetary systems
WHI takes advantage of new capabilities in
observations and models to advance our
understanding of the 3-D interconnected
heliophysical system. The campaign will
begin with the origins of solar structure and
variability and will trace their impact to the
outer reaches of the heliosphere.

IHY-UN Instrument Program
• Placing small inexpensive instruments in new
geographical locations can provide new science
• Distributed observatories can continue to provide
useful data after the IHY
• The lead scientist or principle investigator will provide
instrumentation (or fabrication plans) for the
instruments in the array
• Host country provides operation support
• All science shared within team
• Partnerships established at IHY-UN Workshops
• UN committed until 2010 – still time to participate!
