10-12 May geomagnetic storms impacted GPS-guided tractors in North Dakota, causing off-course planting.

During the May 10-12 geomagnetic storms, extreme solar activity affected GPS-guided tractors in North Dakota, causing them to veer off course while farmers were planting crops. The storms impacted precision farming, with tractors reportedly off by 10 feet instead of the usual centimeter accuracy. Farmers were forced to suspend operations until the solar storm effects subsided.
