                                PLANETARY SECTION

Since the last bulletin was issued in April, a great deal has happened in space to
make the work of we astronomers more valuable than ever before .. and the need
for good observations is even more apparent.

As you are aware, the International Union of Amateur Astronomers was founded this
year and the machinery set up for the exchange of information. Observations can

     The fourteenth comet of 1967 was discovered in the morning sky
by Ikeya and Seki on December 28th, apparently within minutes of each
other. Tsutomu Seki has recently been sweeping with 5-inch 20 power
binoculars, and he also found Cornet 1966d with these. They give a 3° field

1967 promises to be an exceptional year for our Society. As I prepare this bulletin L
am aware that two Centres have planned Centennial projects.   Ottawa Centre members will
be taking a Centennial Trip in late August to Algonquin Park, where they will camp for a
week and photograph the entire summer night sky. The Montreal Centre has two projects;

MARS

As Canada's 100th birthday is also the year for one of the more favourable apparitions of
Mars, the National Co-ordinator suggests that a 1967 map of Mars should be prepared by
this Section as our Centennial contribution. A project of this magnitude requires the
active participation of observers from all Centres of the Society to ensure its success.

If members of your Centre have been active in the lunar occultation field, please see
that material that could be used for a lunar occultation display at the General Assembly
in Montreal in May is reported to the President of your Centre. Photographs of ob-
servers and observing sites would be appropriate.
