I was out chopping wood in our back yard of our home in Stoughton with a hatchet when I saw several flashes of light. The entire sky was blanketed with clouds but looking up I could clearly see a bright blue light. This wasn't the first time I witnessed such a phenomenon, back on November 22, when a snowstorm hit I was sitting out on the front porch enjoying a cup of hot chocolate when a i saw one flash of light. This time however, the bluish light flashed several times, illuminating the clouds. It could have been lighting though I heard no thunder at all. I called my father outside to witness the phenomenon and his best guess was that it was an airplane though neither After viewing the flashes which occurred every 1-2 minutes we decided to head inside.
