Coronal holes cause an increase in solar wind speed and are usually much less "dense" than CME's that result from a solar flare, but they have a much longer duration. Most noticeable effect are active aurora's with lots of motion and some radio communication interference.
Solar Terrestrial Activity Report has a great report on current solar activities effect on radio communications. May be of interest to some of you HAM operators. this is their most recent report on radio propogation:
"Propagation Long distance low and medium frequency (below 2 MHz) propagation along east-west paths over high and upper middle latitudes is poor. Propagation along long distance north-south paths is fair to poor. Trans Atlantic propagation conditions are monitored every night on 1470 kHz. Dominant stations tonight: Radio Vibración (Venezuela) from 23 until 02h UTC, then gradually CPN Radio (Perú) got the better signal. A couple of interesting unidentified stations from South America were noted on 790 and 620 kHz just after local sunrise. Only a few stations from North America could be heard, 1510 WWZN had the best signal along with 930 CJYQ]."
Spaceweather.com tracks a lot of this info and has links to all the other important sites.
