  2. 2 3 1 2 3 1 GOES and RHESSI Solar Event Light-curves Three separate events may be distinguished in the GOES and RHESSI light- curves with start times: E1: 07:30 UT E2: 07:39 UT E3: 08:00 UT Events 1 and 2 are quite impulsive even in the GOES data Event 3 is more gradual and of longer duration

  3. Culgoora radio data • Two type II bursts were observed; • DRIFTING: 180 - 25 MHZ, 0739 UT-0750 UT;SHOCK SPEED ~550 Km/s (2) DRIFTING: 100 - 35 MHZ, 0748 UT-0757 UT; SHOCK SPEED ~ 850 Km/s From fplasma = 9√ne kHz, heights of first detection are h1 ~ 2. 105 km → Dt1 ≥ 6.5 min h2 ~ 3.105 km → Dt2 ≥ 6 min Thus by relating to the event start times, burst #1 is associated with E1 and the faster burst #2 with E2 – burst #2 probably overtakes and merges with the burst #1 shock 19-Jan 20:00UT - 20-Jan 07:59 UT
