"19:29 UT on 4 November 2003. This one saturated the X-ray detectors on the NOAA's GOES satellites..." Estimated strength: X28-45.
The damages were minimal, [https://en.wikipedia.org/wiki/2003_Halloween_solar_storms https://en.wikipedia.org/wiki/2003_Halloween_solar_storms] so it's good to keep this in mind for perspective. The Quebec power outage of 1989 (lasted nine hours) was caused by an X-20 flare.
