Note on tracking Sun-Earth connection event Observer: SD ICME 1.1.Catalog # Identified in ICME catalogs: Richardson & Cane List RC Catalog Disturbance start time: 2013/05/25 20:00 UT Ejecta start time: 2013/05/25 23:00 UT Ejecta end time: 2013/05/26 22:00 UT dv= 140 km/s, v = 660 km/s, vmax = 750 km/s Bmax (nT): 7 Dst: -47 Suggested source CME: V_transit: - km/s 1.2.Comments Overall ICME quality index: ICME signatures: Rotation of Bz Increase in velocity and afterwards smooth decrease Lower proton temperature than expected temperature Based on 750 km/s -> search window 55.4074 hrs or 2.30864 days -> 2013/05/23 12:35:33.344 2. CME 2.1. A. Candidate A A.1. LASCO: #CME 2013/05/22 08:48 UT, partial halo (from CDAW) angle: 210, velocity: 687 km/s SEEDS vel C2: 529 km/s (09:12 UT) A.2. STEREO: Major CME on both COR2-A and COR2-B. COR2-B suggests that CME was not moving forward. A.3. AIA & GOES: Limb event (~N35), maybe one foot of erupting structure was behind the western limb. A.4. Comment: Unlikely the source of disturbance due to the location of the eruption. 2.1. B. Candidate B B.1. LASCO: #CME 2013/05/22 13:25 UT, halo (from CDAW) angle: 360, velocity: 1466 km/s SEEDS vel C2: 693 km/s B.2. STEREO: Major CME on both COR2-A and COR2-B. COR2-B suggests that CME was not moving forward (mostly). B.3. AIA & GOES: M5.0 class flare from NOAA AR 11745 (N14W87). Flare started around 13:08:00 UT on 2013/05/22. B.4. Comment: Likely the source. Though it was a limb event, WDA suggest that some effect can be observed around the Earth. 2.1. C. Candidate C C.1. LASCO: #CME 2013/05/23 16:48 UT, partial halo (from CDAW) angle: 123, velocity: 266 km/s SEEDS vel C2: 286 km/s C.2. STEREO: Major CME on both COR2-A and COR2-B. COR2-B suggests that CME was not moving forward (mostly). C.3. AIA & GOES: limb event C.4. Comment: Unlikely the source due to the time of occurrence and speed of the CME. 3. Other Comments 4. Summary SW index: 1 Source index: 2 Overall index: 2 Filament: WAD: Yes
