Coronal Mass Ejection Hits Earth

Posted by CmdrTaco on from the duck-and-cover dept.

astroengine writes "On Tuesday, the Earth was hit by a coronal mass ejection (CME), triggering a 'moderate' geomagnetic storm, igniting aurorae at high latitudes. The CME in question was launched from the sun early on Sunday and space weather scientists predicted its arrival on Aug. 3 — the vast magnetic bubble of solar plasma arrived on schedule."

    We lost a pair of SNE2000 SDSL ethernet extenders (bridges that use a plain dry copper twisted pair, in our case for several thousand feet between two buildings) when the geomagnetic storm first hit. The devices at both ends failed (DSP chip burnout) exactly simultaneously.

    Doubt it! In whose relativistic frame of reference did they occur simultaneously? I hope you don't say "the middle of the cable" because that doesn't take into account the rotation of the earth...
