Hawk,

Here's a paper from Paul LaViolette with some data found in the Greenland Ice Sheet that falls in line BOTH WITH a solar event linked to the Younger Dryas mass extinction AND the conclusion from a paper I posted yesterday [ Message 31979671 ] that states, "Based on the direct solar observations and the indirect arguments presented in this study, solar flares with energy fluences above about X40 are very unlikely for the modern Holocene-era Sun."[ agupubs.onlinelibrary.wiley.com ]

"EVIDENCE FOR A SOLAR FLARE CAUSE OF THE PLEISTOCENE MASS EXTINCTION"

"The radiocarbon and cosmogenic Be evidence examined here suggests that the mass extinction had a solar cause. Several studies indicate that toward the end of the ice age the Sun was far more active than it is today. Zook et al. (1977) studied solar flare tracks etched in lunar rock micrometeorite craters and concluded that around 16 kyr ago the average solar cosmic-ray intensity was 50 times higher than at present, declining to 15 times higher by 12 kyr BP, and eventually reaching the present activity level.

Elevated 14C concentrations found in the surfaces of lunar rocks also indicate that for a period of 5000 yr prior to 12 kyr BP, the Moon was being exposed to a solar cosmic-ray flux averaging 30 times higher than the present flux (Zook 1980). Jull et al. (1999) have measured the concentration of 14C versus depth in lunar rock 68815 and several lunar cores and found the levels to be elevated, consistent with a 25% elevation of the cosmic-ray exposure (solar plus galactic) over the past ~30,000 yr. LaViolette (1983, 1985, 1987, 1990, 2005) attributed this elevated solar activity to the entry of large quantities of dust and gas into the solar system and proposed that excessively large solar cosmic-ray events were a primary cause of the Pleistocene megafaunal extinction. 14C data from the Cariaco Basin ocean sediment record as well as nitrate ion data from the Greenland ice core strengthen this conclusion. They suggest that one or more solar proton events occurring near the beginning of the Younger Dryas were sufficiently large to have produced radiation levels at the Earth’s surface fatal for unprotected mammalian species.

It's not exactly what you were looking for but it adds to the reasons to be somewhat less expectant of an enormous CME any time soon.
