EIT will provide some support for JOPs, but not for all. Blinkers study on Tuesday will begin at ~ 14:30 UT which roughly the when MDI will be getting high rate data. SUMER will support using their explosive events study... MDI will be taking magnetograms in their high resolution field-of-view with a 1 minute cadence. UVCS and LASCO CME Watch Methodology: LASCO will use the warning time (10-20 hours) and to warn UVCS. They will observe at 2.5 - 3 Rs. In the case of a smoothly accelerating CME. C1 observes slow velocity: ~40-50 km/s at about 1.3 Rs C2 eventually sees this: 200-300 km/s
