Both of these bursts are classified as Type III solar storms. The possible reason for this emission is the active area surrounding the large sunspot AR3053. This sunspot erupted later the same day at 20:49 UT (00:49 UAE local time), resulting in an M2.5-class solar flare that caused a brief shortwave radio blackout over North America's Pacific coast.
