Increasing threat of strong solar flares, CME hit anticipated

Solar activity has been low in last 24 hours, however, that might change today and in the coming days. New Active Region 2051 (S10W44, Dac/beta-gamma-delta) is growing rapidly and is now harboring energy for X-class solar flares. Eruptions from this regio
