From Jonathan McDowell (Harvard / Smithsonian Center for Astrophysics) :
"On Mar 27 India's Defense Research Development Organization (DRDO) launched the first PDV Mk II antisatellite interceptor from Kalam Island. After a three minute flight the missile collided with the 740 kg Microsat-R satellite in LEO. Microsat-R was in a 260 x 282 km x 96.6 deg orbit at the time, travelling north over the Bay of Bengal; PDV-II flew south from Orissa to intercept it. PDV-II is reported to be a three stage vehicle - two solid boost stages and a kill vehicle with liquid-propellant terminal guidance thrusters."

This is the first confirmation I've seen that the ASAT test may have been successful. The report also identifies the target satellite.
