2. 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?

3. 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

7. 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?
