On February 14, a bright shock appears on February 14 from the WSA / Enlil Model Analysis of this incident. This is first seen in the SOHO / LASCO C2 Imagery at 01:25 UTC. This phenomenon has produced an asymmetric halo corollary mass injection.
On February 12, 2018, the Refractive active area of 2699, the long-term 1.5-1.5 solar flare erupted and this event started at 00:15, increased at 01:35 and ended at 03:21 UTC. One G1 this minor geomagnetic storm clock has been effective on 15th February. In response to the arrival of this C-1A,
the clock of AG1 minor geomagnetic storm is effective for 15 February 2018. This is because CME's forecast time has slowed down with the prediction of running these WSA-ANL CME models. Its current background solar wind speed is slower than regular model predictions.
