Reconnection events along neutral lines form the photosphere to higher heights in the atmosphere are believed to be behind the formation of filament channels, the seeds of CMEs. A large number of cancellation events in coordination with SST (Halpha - looking for heating events such as Ellerman bombs) is needed to elucidate the physical processes behind the creation of filament channels. request to SOT Similar to HOP330 on 2017 April 22 at 14UT, but twice as wide (i.e. 20"). ivo://sot.lmsal.com/VOEvent#2023-05-10T08:00:00Z
