Several highly unusual solar particle events occurred in August 2002, with high ^3^He/^4He ratios and enormous enhancements of heavy isotopes [5]. By examining proton, electron, and heavy ion intensities, Hα, X-ray, and radio flares and particle arrival times relative to them and to coronal mass ejections, we find that the 20 August 2002 event was the largest impulsive event yet seen in this solar cycle at energies >10 MeV/nucleon.
