Letters to the Editor

from Alan HEATH in CMO #218

@ . . . . Enclosed are a few more observations of Mars to date. Observing conditions here continue to be poor and the observation of May 10 is the best so far but is itself poor.
  The interesting thing is that there seems to be a number of dates when surface features have been seen with a blue filter but a notable absence of Syrtis Major in blue.
  Hoping all is well.
