Attention: Mr. Broadfoct.

Dear Mr. Broadfoot,
The Canadian Astronautical Society was most pleased at
the opportunity of having a joint meeting with the Royal Astronomical
Society of Canadain Novemberlast. It was an excellent turn-out
and I thought Mr. Rose gave a fine speech. Afterwards, I mentioned
to you that we had carried out somework during the early Sputnik days
on satellite tracking, both visually and photographically, and I was
interested to learn that your Society have an active Moonwatchgroup;
which, I understand, is connected with the Smithsonian Astrophysical
Observatory. The Canadian Astronautical Society had considered forming
such a group at one time. We still have an active nucleus of
persons interested in this general area and we still receive data on
satellite orbits from S.A.O. I believe I mentioned to you that we
have written a Report on "A method of estimating the elevation angles
and the azimuth angles for viewing a satellite in orbit". I have
enclosed a copy for your retention and use. I can get you more
copies if you desire.

I hope that it will be possible for our two Societies
to get together In future on joint ventures, as we have done this Fall.

It is quite likely that a few of our people would be
interested in your Moonwatch activities and, if you have any literature
on this, we would be pleased to receive it.

Yours very truly,

P. A. Lapp.
