The amateur Dae-am Yi from Yeongwol-kun, Korea found this comet on a CCD image taken with a 90mm f/2.8  tele lens and Canon 5D camera on March, 28 2009.
He found a 1' greenish coma on two 60 sec. images.
Independent of this Robert D. Matson from California detected some days later the same comet on SWAN images.
