Additional Comments

The Co-rotating interactive region (CIR) ahead of the high-speed stream arrived late on 29-APR. Currently the solar wind speed is rising, indicating the onset of the fast solar wind from the re-current coronal hole. Geomagnetic activity levels are expected to rise in the coming hours as a result and ACTIVE to STORM G1 conditions are anticipated with a small chance of STORM G2.
The slow and faint CME associated with the M6 flare on the 26-APR may arrive during the 1st interval, although the confidence in this is low.
