Note on tracking Sun-Earth connection event ICME Event: 2013/08/20 Observer: Suman Dhakal on 2019/05 (part 1); 1. ICME 1.1. Catalog # Identified in ICME catalogs: Richardson & Can List RC catalog: Disturbance start time: 2013/08/20 22:27 UT Ejecta start time: 2013/08/21 08:00 UT Ejecta End time: 2013/08/21 14:00 UT dv = 30 km/s, v = 460 km/s, vmax= 470 km/s MC index: 1 Dst: -26 nT Suggested source CME: V_transit: km/s 1.2. SW Plots Overall ICME quality index: 3 SW type: EJ+SH ICME signatures: Bmax: 6.1 nT varying Bz. Other ICME signatures: low proton temperature, and low plasma beta. Peculiar behavior: Variation in velocity is hard to discern Plasma density plot is not available Fluctuating plasma beta. Search Window: Upper bound: Disturbance speed 430 km/s: 91 hrs: Lower bound: Transit speed < 700 km/s: 60 hrs < 2. CME 2.1. A. Candidate A A.1. LASCO: #CME 2013/08/16 at 11:48 UT, halo (from CDAW) moving with a velocity of 478 km/s A.2. STEREO: not moving in the front side. A.3. AIA and GOES: A.4. Comments: Unlikely the source because of direction. 2.2. B. Candidate B B.1. LASCO: #CME 2013/08/16 at 15:48 UT, halo (from CDAW) moving with a velocity of 555 km/s B.2. STEREO: not moving in the front side. B.3. AIA and GOES: B.4. Comments: Unlikely the source because of direction. 2.3. C. Candidate C C.1. LASCO: #CME 2013/08/17 at 19:12 UT, halo (from CDAW) moving with a velocity of 1202 km/s C.2. STEREO: halo CME in COR2-A and COR2-B. C.3. AIA and GOES: corresponding to M3.3 class flare peaked at 18:24 UT from AR 1818 at a location S04W30. C.4. Comments: Unlikely the source because of velocity. 2.4. D. Candidate D D.1 LASCO: #CME 2013/08/19 23:12, halo (from CDAW) moving with a velocity of 877 km/s. D.2 STEREO: not moving in the front side. D.3 AIA and GOES: D.4 Comment unlikely the source due to direction and time of the eruption. 3. Other Comments 4. Summary SW index 3 Source index 3 Overall index 3.
