I'm not seeing anything currently earth facing @ sun that would produce a flare (some activity on incoming limb but that would put it 5 days or better out). There is a coronal hole that could ramp up solar wind speed in next 24-48hrs again, small but seems focused and earth aligned. Sometimes the impact of these solar winds can mess with the earth's magnetic shields.
