Also note the straight lined arrow touching the 25 degree line, at just to the right of the surface geyser. This arrow shape disappears at the end of the solstice day, western hemisphere the 21, while it’s 22 in East.
Also important, focus your attention on the other side of the sun, to the east, and see the straight lined triangle-shaped solar flare that takes shape during the active geyser on the west. It evaporates when the geyser dies out.
