Northern Lights Now – A large coronal hole was pointed directly towards Earth on April 9th and 10th. The high speed solar wind from that exposed area is should impact Earth on April 13 and 14. Space weather forecasters are expecting two consecutive days of geomagnetic storming. That could bring several opportunities for Aurora hunters to experience the Northern and Southern Lights. Here’s an image from SDO from late on April 9 in AIA 211, a wavelength that makes it easy to see coronal holes:
SWPC is calling for two periods of active Aurora (G1 level storming). The first period is early on April 13 and the second is Early on April 14. For North American Aurora viewers this is in prime evening viewing time. Europeans viewers will have to stay up past midnight. See the NLN Aurora cast for April 13 and 14.

Note: It is not an error that both days have the same profile throughout the day. The is what the forecasting models have predicted.
