2. SMEI Detection on Nov. 7 of Earthward CME that
Drove Storm Peaking Early on Nov. 8.
Real-time Prediction of Storm Onset made
Nov. 7 ~22:00, just before Storm Onset.
03:25 UT
10:10 UT
15:15 UT
Top arrows: Main part of Earthward CME loops (see LASCO images).
Bottom arrows: A separate CME loop emitted earlier & passing SE
of SMEI into the anti-solar hemisphere.

3. Elongation (deg. from Sun) vs time plot showing SMEI
obs. on Nov. 7 (d312) and forward & back-extrapolations
Back-extrapolation to Sun suggests onset early on Nov. 6 (311) or on Nov. 5.
Likely assoc. is LASCO halo on Nov. 6, but one also occurred on Nov. 5.
