These are almost all in the last 3 weeks, with about 15 in the last week. I follow the stock market closely, just anecdotally I have never seen this many in a year, let alone a month. This is all around the world, the part that really caught my attention was telecom. Zain Telecom, France Telecom and Syntel were all within the last 2 days, telecom would be heavily affected by solar flares and would likely know what was coming.
