1. OnLine Solar Wind Data Now Available From SOHO
============================================================================

From: Fred Ipavich  (ipavich@umtof.umd.edu)

We have recently established a WWW page for accessing close-to-realtime
solar wind data obtained from the Proton Monitor (PM) on the SOHO spacecraft.

SOHO is never in the magnetosphere and enjoys excellent data coverage.  The 
data on the Web page are typically between a few minutes and a few hours old.

The PM is a subsensor of the MTOF instrument, which is one of the 3 
time-of-flight instruments comprising the CELIAS experiment.  MTOF determines 
high resolution mass spectra of heavy solar wind ions and uses a very wide 
bandwidth energy-per-charge analyzer to maximize counting statistics.  The PM 
was designed to assist in the interpretation of MTOF data and for that reason 
uses a similar wide bandwidth analyzer that limits the accuracy of derived 
solar wind parameters.  A preliminary comparison of PM parameters with those 
derived from the SWE instrument on the WIND spacecraft (courtesy K. Ogilvie 
and A. Lazarus) results in the following values for the sigma of the 
distribution of the ratios of parameters derived by the 2 instruments:

      proton bulk speed < 5%, density < 20%, thermal speed < 40%.
