Just that it might affect GPS or power grids.
3-day Solar-Geophysical Forecast issued Mar 07 22:00 UTC Solar Activity Forecast: Solar activity is expected to be moderate to high. M-class level activity is expected to continue and there continues to be a good chance for an additional major flare and/or proton producing event from Region 1429. In addition, the growth trend in 1430 suggests that it may also contribute to the M-flare activity during the next three days. Geophysical Activity Forecast: The geomagnetic field is expected to be active initially on day 1 (08 March) but is expected to increase to major storm levels with a likelihood for isolated severe storm levels after the arrival of the CME from today's X5/full halo event. The arrival time is estimated to be sometime between 0600-1000Z. Minor to major storm levels are expected to continue partway (6-12 hours) into the second day (09 March), but a decline to predominantly active levels is expected for the remainder of the day. Predominantly unsettled levels are expected for the third day (10 March). The greater than 10 MeV proton event is expected to continue through the first day and is also likely to continue partway through the second day. The greater than 100 Mev proton event is expected to slowly decline over the next 24 hours.

WE may only 1 hour left on ATS!!!
Update:
UPDATE 03/07/12 2:30pm EST
UPDATE 03/07/12 2:30pm EST NASA models using data from the Solar Terrestrial Relations Observatory (STEREO) and the Solar Heliospheric Observatory (SOHO) have now provided more information about the two CMEs associated with the two March 6 flares. The first is traveling faster than 1300 miles per second; the second more than 1100 miles per second. NASA's models predict that the CMEs will impact both Earth and Mars, as well as pass by several NASA spacecraft – Messenger, Spitzer, and STEREO-B. The models also predict that the leading edge of the first CME will reach Earth at about 1:25 AM EST on the morning of March 8 (plus or minus 7 hours). Such a CME could result in a severe geomagnetic storm, causing aurora at low latitudes, with possible disruption to high frequency radio communication, global positioning systems (GPS), and power grids.

I am just going by what NASA and NOAA have reported.
