Scientific paper

The largest relativistic (~1 GeV) solar proton event of the current cycle occurred on Easter (April 15) 2001. This event was observed as a ground level enhancement (GLE) by the 11-station ``Spaceship Earth'' network of neutron monitors. We derive density and anisotropy time profiles and fit these with numerical solutions of the Boltzmann equation. Interplanetary transport was rather diffusive in this event, with a radial mean free path in the range 0.1-0.2 AU. We also find that particle injection at the Sun peaked at 13:47 UT. In comparison, the type II radio burst started at 13:48, type IV at 13:52, and the soft X-ray peak (an X14.4 event) was at 13:50. Supported by NSF grant ATM-0000315 and the Thailand Research Fund.
