  1. Choose an image each from Australia and Japan,whose time markers are as close as possible.
  2. Make sure both images are good quality and that Venus and some sunspots are clearly visible in each.
  3. For each image, click on 'Venus' and then place the cursor as centrally as possible on Venus' shadow.
  4. Then, for each image, choose a sunspot, noting its position relative to Venus' shadow. Again, mark it with the cursor. Make sure you use the same sunspot in each image!
  5. Finally, mark the centre of each image with the cursor.
  6. Click 'Submit' and your Earth-Sun distance will be calculated according to the 'Method of shadows' (see Section 5 of the reference document).
