Title: Apollo 12 Solar Wind Spectrometer Data

Apollo 12 Solar Wind Spectrometer Data
2
Apollo 12 SWS
  • The Solar Wind Spectrometer was designed with
    the objective of detecting whatever solar wind
    plasma might strike the surface of the Moon. The
    instrument consisted of an array of seven
    modulated Faraday cups.

The center cup faces vertically upward and the
six other cups are equally spaced at 60 degrees
from the vertical. All points in the lunar sky
are observed by at least one cup.

Apollo 12 and Apollo 15 Sites
At the Apollo 15 location, the magnetic field is
low, but at Apollo 12, the magnetic field is
about 38 nT. This can perturb the solar wind.

Using of Apollo SWS Data
5
Accessing the Data
53 records for 1 hr
20 records for 28 s
Difficult to read date format - could use a
column with floating fractional day of year -
Kaleidagraph took me 4 minutes with special
format.
6
Plotting Data
1 hour data
28 second data
7
Documentation
Documentation seems adequate and
self-explanatory Some articles of relevance may
be difficult to track down (e.g. Clay et al.
(1975) Journal of Geophysical Research, 80,
1751.) Could pdfs be included with the data?
