Scientific paper

The NASA STEREO mission was launched in October, 2006. The two STEREO spacecraft are in heliospheric orbit about 1 AU from the Sun, one drifting ahead of Earth and one drifting behind. In order to achieve the drift the Ahead spacecraft is slightly closer to the Sun than Earth and the Behind spacecraft is slightly further from the Sun. Since soon after launch, the optical (STEREO/SECCHI) and radio (STEREO/SWAVES) remote sensing instruments began observing transients which are being interpreted as impacts of dust particles. There are three different types of observations: (1) transients in the potential measured by the SWAVES radio experiment, (2) optical tracks in the SECCHI (COR1, COR2 and HI-1) images and (3) results from the on-board image scrubbing algorithm in HI-1. There is some agreement in the onset times between the three detection methods, but not always. The frequency of events detected by STEREO-A and STEREO-B, which are now about 45 degrees apart, is quite different. We will present the observations and our preliminary interpretation.
