Comment Section
- A perfect CME-ICME chain event (J. Zhang)
- classical ICME feature: shock + sheath + magnetic cloud
- strong solar signature: X1 flare (S17W08); halo CME, fast and bright
- Propagation Direction is very close to the Sun Earth Line, making this a good event for comparing observations nearer the Sun to in-situ signatures (P. Hess)
Image Data
In-Situ Data
A combination of SWEPAM and MAG data from the ACE Satellite:
The blue lines are an approximation of the CME cloud and the red line denotes the shock.
The results from geometrical modeling in comparison to the in situ data from the Wind spacecraft (C. Moestl). The magnetic cloud is of ESW type (right handed), with the flux rope axis pointing southward; the MC has very long duration (48 hours). The shock arrival time is 2012 July 14 17:38 UT.

results of geometrical modeling (C. Moestl):
Jmaps along the CME leading edge position (about <math>7^{\circ}</math> S of the ecliptic) from STEREO A and B
De-projected Height Time Plots of the shock and ejecta fronts as obtained from the GCS (measured by Hess) (for GCS details, see Thernisien 2006) along with velocity and acceleration profiles determined from the Aerodynamic Drag Model.
Fitting parameters in GCS Model: Carrington Longitude: 80.5738 degrees, Latitude: -8.9442 degrees, Tilt Angle: 58.1364 degrees, Aspect Ratio: .437363, Half Angular Width: 31.8636
