Data from the Celias/Mtof
on the SoHO Spacecraft
Figure APM measurements, 8 through 13 July 1996, 5-min averages.
Energetic particles were observed from a flare on 9 July.
Figure B PM observations of 12 July 1996, 30-sec averages.
Figure 1 PM observations of the interplanetary shock on 10 Jan 1997,
PM observations of the interplanetary shock
on 9 Feb 1997, 30-sec averages.
measurements (2 min averages) during the density rarefaction on 10 Feb 1997.
The gray solid line represents the density as derived from the moment technique,
while the points represent the density obtained from the fitting technique.
PM measurements (10 min averages) for the 3-day period 8 Feb through 10 Feb
1997. A high speed stream arrives on 8 Feb, a shock on 9 Feb
(see Figure 2 ), and the density
rarefaction on 10 Feb (see Figure 3).
PM observations of a POSSIBLE weak, interplanetary
shock at 0117 UT on 10 April 1997, 30-sec averages; note the lack of a strong signature
in the density profile.
PM observations of a shock
at 1258 UT on 10 April 1997, 30-sec averages;
note the solar wind flow direction in the plane perpendicular to the ecliptic
(bottom panel) turns positive after the shock, indicating flow from the south.
Energetic particles were detected from a flare on 7 April.
Shock detected at 0056 UT on 15 May 1997, 30-sec averages; energetic
particles were detected from a flare on 12 May.
Shock detected at 0447 UT on 20 May 1997, 30-sec averages.
Shock detected at 1324 UT on 25 May 1997, 30-sec averages.
Shock detected at 0020 UT on 1 October 1997, 30-sec averages. Also see the HSTOF data for the same time period. More STOF data is available at the STOF data site.
