Onset time analysis of impulsive electron events at 1 AU suggest that there are two classes of events: (1) events with a solar release time in close temporal agreement with solar hard X-ray (HXR) flares, and (2) events with a delayed solar release time relative to the HXR emission that seem to be accelerated later possibly at coronal shocks. Simple onset time analysis, however, are criticized for not taking propagation effect properly into account producing falsely delayed release times. Here we present a further test of the existence of two classes of events by comparing the in-situ observed electron spectra with the solar HXR photon spectra remotely observed by RHESSI. For events with a good temporal agreement, a clear correlation between the spectra has been reported indicating a common acceleration mechanism. Delayed events have not yet been analyzed. However, if indeed a second acceleration mechanism independent of the HXR flare exists that release energetic electron into interplanetary space, no correlation between the in-situ observed electron spectra and the HXR photon spectra is expected to be found.
