Feedback - November, 2003 QST

Thanks to the many QST readers who pointed out that we were snookered by the fake photo of the August 14 blackout in the Northeastern US (see October 2003, page 80). Real power blackout satellite images are available at several Web sites, including the US Air Force Defense Meteorological Satellite Program (https://afweather.afwa.af.mil/news/black_out.html), the Universe Today Web site (http://www.universetoday.com/html/archive/2003-0818.html) and NASA's Earth Observatory site (http://earthobservatory.nasa.gov/Newsroom/NewImages/images.php3?img_id=16273). ARRL regrets the error.
