Major smashups between rocky bodies shaped our solar system. Observations of a similar crash give clues about how frequent these events are around other stars.

Solar Activity
Solar activity reached moderate levels following a long-duration M1.1 flare at 20/1948 UTC from Region 3897 (S12W90, Dao/beta) as it transited the west limb. This region also produced the majority of the C-class flare activity during the period. Region 3898 (S16W27, Cao/beta) exhibited slight decay early in the period, but then had some redevelopment later and managed to produced a C3.5 flare at 20/0632 UTC. Region 3901 (S07E35, Dao/beta-gamma) added a pair of low-level C-class flares, but remained mostly unchanged. The remaining regions were quiescent. New Region 3902 (S17E70, Cso/beta) was numbered. While several CMEs were observed in SOHO/LASCO coronagraph imagery, none were deemed Earth-directed.
Solar Wind
Solar wind parameters reflected a weakly enhanced solar wind regime early, before transitioning to background levels the latter half of the period. Solar wind speeds ranged between 350 km/s - 400 km/s. Total field strength averaged near 10nT, reached a peak of 13 nT, then decreased to remain near 5-8 nT the last half of the period. The Bz component fluctuated between +9/-10 nT before turning mostly north, and the phi angle was predominantly in a positive orientation.
Energetic Particle
The greater than 2 MeV electron flux was normal to moderate and the greater than 10 MeV proton flux was at background levels.
