Additional Comments

Four minor M-class flares were produced by solar region 14513 over the last 24hrs. This is a complex region currently in a Earth-facing position. However, no Earth-directed coronal mass ejections were observed.
The next increase in geomagnetic activity is expected from the second forecast interval onward when a high-speed solar wind stream from a coronal hole is expected. This could bring ACTIVE to STORM G1 periods.
