How this mode works
Planetarium and sky-map problems sometimes leave bright stars out of a sky and ask which ones are missing, as in the problems of Section O1.9. A tap counts when it lands within 3° of the missing star. After the answer the star is put back, ringed and named, and after a miss the chart also draws the way to it from stars that are on the chart. Every star you are asked about goes into the same spaced review as the other star modes, so it comes back in the daily round.
