GCS paramters and measurements are shown in Measurement File


This is the drag model fitting for my measurements of the March 17, 2013 ICME. The fitting parameters are

Front	Gamma (/km)	V_0 (km/s)	V_SW (km/s) (Determined by ACE)	R_0 (R_S)
Shock	1.35 e-8	1166.9	429.3	7.84
Ejecta	5.41 e-8	1199.0	429.3	7.38

This event was more difficult than I expected to fit and find a good GCS fitting in all three viewpoints (STEREO A + B, LASCO). Eventually I was no longer able to discern the flux rope in the HI-1 FOV so I focused on just the shock. Still the fitting and measurements seem to be pretty effective.



This event has a clear surface signature with post flare loops, associated with an M class flare beginning at 05:46 UT at AR 11692.

And the event is well observed by both STEREO A and B
