GOES/RHESSI Overview M1.5/1 N flare from the outskirts of AR 9973
Flare at S19 E29 GOES 03:50 – 03:57 – 04:01 Type II 03:56 – 04:06 Type III: 03:58 – 04:03 Wind/WAVES 12-30 10-12 50-100 30-50

Summary Spatial & temporal evolution of the June 01, 2002 Flare
Outward electrons only after the eruption – similar to 4/21/02 Shock-accelerated electrons or escaping due to eruption?

Microwave Light Curve TRACE 195: 03:53:33, 03:53:50, 03:54:07, 03:55:32, 03:56:6, 03:56:57 Two phases as in HiRAS spectrum First phase has three spikes at 3:53:40, 3:53:50, & 3:54:15 3:55:25 Second phase has two peaks: 3:56:10 & 3:57:05 Second Phase has eruption and type II (no LASCO data )
4
June 01 Radio Event Type II 03:56 – 04:06 180 – 25 MHz
5
HiRAS WAVES Type III starts at 03:58:30 in the metric and continues to WAVES range. There is no other activity on the Sun The type III is related to The event in question 1.5 min after the metric Type II
6
B structure in the Flare Region
Green: B + Red: B – Yellow: B lines

Microwave Sources Shift between the Two Phases
Color & Black Contr: 03:53 Gyroresonance source does not shift between 3:53 and 3:59:30 Flare source does In phase 2, the western footpoint is dominant? Gyr-Res Free-free Red Contr: 3:59:30

The Largest Peak in X-rays & 17 GHz
The RHESSI foot points (color contr) on the MDI magnetogram. The microwave centroid between the RHESSI footpoints resolution? (nominal resolution is 15”) RHESSI Foot points + 17 GHz Contr 03:53:49 UT
