The latest ENLIL model shows a direct hit from a coronal mass ejection on 11 August. Combined with the coronal hole high speed stream this could lead to a G1 geomagnetic storm. A G1 (minor) watch has already been issued for 11 August. You can always check the latest models here.

Due to the currently increasing coronal hole high-speed stream and the arrival of the CME observed on July 16th, the geomagnetic activity is expected to increase to active and minor storm (G1) levels early on July 19th. A second peak of activity is expected on July 20th due to substorms. The geomagnetic environment will return to unsettled levels later on July 20th.

The ENLIL cone model predicts a direct hit from an earth-directed CME on July 13th. The CME's speed is low (<500km/s) so it will not trigger a major geomagnetic storm but it will be able to disturb the geomagnetic environment.

This is a custom composite image from the HMI and AIA instruments onboard the SDO spacecraft. It highlights the complexity of two of the earth-facing regions at the moment (1785 and 1787).

Despite these big and complex regions, the activity remains at low levels with X-ray flux occasionally peaking in the "C" range. You can see the full-disk composite here.

A slow moving CME due to an eruption on Sunday June 30th will impact Earth on July 3rd. Although the ENLIL model estimates a direct hit, this coronal mass ejection is neither fast or dense and it will not trigger a significant geomagnetic storm.
