WAITING FOR THE CME: April 6th passed quietly, contrary to predictions of a CME strike and geomagnetic storm. However, there is some confidence that the CME is still coming. NOAA forecasters expect a glancing blow on April 7th, possibly sparking minor G1-class geomagnetic storms.

OFF-TARGET CMEs MISS EARTH: A CME missed Earth on April 6th. Another CME missed Earth on April 7th. Now a third CME is coming--hurled into space yesterday by an erupting filament of magnetism on the sun. It is expected to miss, too. Ripples from the near miss might cause minor geomagnetic unrest on April 11st.

WEAK IMPACT: Arriving a day later than expected, a CME grazed Earth's magnetic field on April 8th (0400 UT). It was a weak, glancing blow that almost escaped detection. The CME was hurled into space near the edge of the Earth-strike zone on April 3rd by a "canyon of fire" filament eruption. Its tardy arrival did not spark a geomagnetic storm.
