Tonight's sketch was made under challenging conditions, with a lot of time spent waiting for convective cells of boiling air to pass over. Not a lot of detail to see as a result (Seeing 4A to 5A). Here's my latest capture compared with a previously posted sketch to show how much change there has been in the vicinity of the GRS. There was the usual 'bow' wave of cloud, with the GRS appearing to 'float' on its outstretched palm, but I couldn't make out the SEB in the wake of the spot at all,except for a bunch of turbulent swirls. I heard about this recently and wanted to see for myself. Yup! There is was!
Anyone else sketching this?
