I am aware how the real situation was during WW2, or is when flying.But asking the question otherwise, avoiding Coriolis, on a steady situation, on land, using the limb of the Sun:how do you make the observation?how do you align the bubble and the Sun? alternatives to the pictures.expected accuracy? with 2' or 1' of resolution in the vernier--
