Additional Comments

The combined arrival of two coronal mass ejections (CMEs) observed on the 27th and 28th June is anticipated during the first and second forecast interval. The CME impacts may also combine with coronal hole high speed stream effects, further increasing geomagnetic activity in the coming days.
Periods of ACTIVE and STORM G1/G2 geomagnetic conditions are expected.
