The first expected impact was due in the early hours this morning (March 19) but appears to be running a little late. Forecasters now say geomagnetic activity is likely to ramp up through March 19-21, with multiple CME impacts expected to trigger minor to moderate (G1 to G2) geomagnetic storms and a chance of stronger (G3) conditions, pushing the northern lights farther south than usual. NOAA space weather forecasters have issued a G2 (moderate) geomagnetic storm watch for March 19-21 as a combination of incoming CMEs and high-speed solar wind is expected to buffet Earth's magnetic field.…
