I WAS ON THE LARKS3 ARRIVAL IN LIGHT PRECIPITATION DESCENDING OUT OF 16,000 FEET. AIRSPEED WAS AT 190 KNOTS AND AS I WAS PASSING 15,500 FEET, HEARD A LOUD BANG AND SAW A BRIGHT FLASH OFF THE RIGHT HAND SIDE OF THE AIRCRAFT. LOOKED UP AND SAW THAT MY RIGHT HAND WINDSHIELD WAS CRACKED. IN IMC IN ICING CONDITIONS AND I ELECTED TO KEEP MY WINDSHIELD HEAT ON AND SLOW THE AIRCRAFT DOWN TO 140 KNOTS. I THEN DECLARED AN EMERGENCY AND PROCEEDED TO DENVER AS IT WAS 30 NAUTICAL MILES AWAY WITH MAINTENANCE AND FAMILIARITY. THE LITTLE I SAW OF THE BRIGHT FLASH SEEMED TO BE SAINT ELMO’S FIRE. NO LIGHTENING OR CONVECTIVE ACTIVITY WAS PRESENT.
