Hi, I am a newbie trying out astronomy after two decades of politics, but I was hoping if someone could help translate the following statement for me (I am not a student, so your not answering an essay question or anything); We report unusual auroral features observed by the DMSP-F6 satellite on January 10 and 11. These features include the shift of the most active region to the morning sector, the shift of the polar cap center toward the evening sector, a large number of sun-earth aligned arcs and the oval-shaped diffuse glow without bright oval arcs. The simultaneous magnetic field observations by the ISEE-3 and IMP-8 satellites, together with a simple magnetospheric modeling result, suggest that the unusual features result from both the unusually large BY and a large positive Bz component of the IMF. The italic/bold section confuses me somewhat. The answer (the last sentence) doesn't really explain it.
