GODDARD SPACE FLIGHT CENTER VISITOR CENTER "DISCOVER 
GODDARD" PRESENTATION:
"THE SUN AND CLIMATE" 
SUNDAY, FEB. 26, AT 1 P.M.

	Did you know that satellite-based measurements have shown that the Sun's 
luminosity cycle changes every 10 years?  Solar luminosity cycles may account for many 
of the known global cold and warm periods in historic times.  Find out more about the 
Earth/Sun relationship on Sunday, Feb. 26, at 1 p.m., at NASA's Goddard Space Flight 
Center's Visitor Center.  Goddard's Dr. H. Lee Kyle, discusses how the seasonal changes 
we are familiar with are driven by the annual cycle changes in the Earth/Sun geometry.

	The Visitor Center is located on Soil Conservation Road in Greenbelt, Md. 
Admission is free.  For further information, call (301) 286-8981.  Sign language 
interpreters are available with seven days' notice, call TDD (301) 286-8103.
