| Comments: | After reviewing yesterday's GOSA Daytime capture, the cam was not on Castle at this time, but very heavy steaming was drifting from its direction starting at 17:19. Cam moved to have Castle in view at 17:38 and a strong steam plume was observed and heavy steaming continued through 18:10. |
