[2.40] Solar Wind and Magnetic field Observations During Whole Sun Months 2 and 3

A.J. Lazarus (MIT), A. Szabo (NASA/GSFC), J. Linker (SAIC), Z. Mikic (SAIC)

We present observations from the Wind spacecraft of the solar wind and the interplanetary magnetic field made during the second and third Whole Sun Month periods (12-25 Aug, 1998, CR1939 and 18 Aug-14 Sept, 1999, CR1953 ). We compare those measurements (extrapolated to the solar surface) with synoptic charts of the photospheric magnetic field made from the Wilcox Solar Observatory. In contrast to the clear coronal hole structures seen during the first Whole Sun Month (CR1913), we see multiple sources of higher speed wind during the approach to solar maximum.
