6. Event summary: 2008
Feb 16, 2:19, 2:45UT (Nakamura et al) and 4:50UT onsets (Gabrielse et al., JGR)
P2 At 2.5RE from nominal neutral sheet
At 20RE, initial activations accompanied by Swd, or bipolar field
Tailward beams close to the neutral sheet
If at the right meridian, P2 shows clear signatures within ~1min of onset
Feb 22, 4:37UT onset (See: Liu, J. et al, JGR)
P1, P2 At 1.5RE from nominal neutral sheet
At 30RE, initial onset accompanied by bipolar field
Twd beams accompany by Swd field
P1 signatures start within ~1min of ground onset
Feb 26, 4:37UT onset (In progress: Angelopoulos, V. et al, Science)
P1, P2 At 0.5RE from nominal neutral sheet
At 20RE, reconnection onset 96 s before ground signatures
Mar 01, 01:48:52UT, 01:54:30UT onsets (See: Runov, A. et al)
P1, P2 At 0. 5RE from nominal neutral sheet
At 23RE, onsets accompanied by tailward flows, southward fields
Twd beams arrived ahead of flows
P1 signatures start within <1min of ground onset
