AB:
Because of their already high energy, suprathermal particles likely serve as the source population for further
acceleration at interplanetary
shocks. The very low solar activity in 2007 and the recurrent corotating
particle events make 2007 an ideal time period to study the abundance of
non-flare associated, i.e. quiet-time, suprathermal particles. Using a
maximum-likelihood method based on Poissonian statistics which is well
adapted to deriving fluxes from small count numbers, we determine the
fluxes of suprathermal particles in 2007. We will present results for
CIRs, high-speed streams, slow wind, and solar wind dwells.
