Bulletin No. 2	Basic Observation Programme	February 15, 1963


    In this bulletin we present an outline of the basic observation programme for
the July 20th eclipse. The programme has been divided into three main sections,
as follows:-

    A. PRECISION OBSERVATIONS, which includes all observations requiring precise
       timing and recording, with the use of atopwatebes, short-wave radio,
       meteorological instruments, etc.

    B. PHOTOGRAPHIC PROJECTS, which includes photography of all phases of the
       eclipse, with and without telephoto lens, filters and other accessories.

    C. VISUAL OBSERVATIONS, made with and without optical aid, and including
       sketches and drawings.

    The attached outline will simply give you some idea of the extent of the
programme and the equipment required so that you can make some preliminary pre-
parations. For each of the three main sections, a separate bulletin will shortly
be issued, giving instructions for each project and a standard report font. Sub-
sequent bulletins will discuss other aspects, such as the selection of an observ-
ing site and the organization of a field station.

    In planning the basic programme, we appreciated the helpful advice and encour-
agement received from Malcolm Thomson and J. S. Locke of the Dominion Observatory.
The little booklet prepared by Dr A. Vibert Douglas for the 1932 eclipse contained
many suggestions that are still useful. We have also drawn on the experience of
the Montreal Centre which organized a five-day expedition to observe the 1954
solar eclipse.

    Enthusiasm is certainly mounting. To date we know of four Centres that are
planning field expeditions. Dr Scatliff of the Winnipeg Centre is organizing a
group that will travel by rail to Willbeach, Manitoba, which is on the C.N.R.
line to Churchill. Individual members of the Edmonton Centre have tentative
plans to travel north. Le Centre Francais de Montreal is organizing a field trip
to the Grand'mere region and has already issued a questionnaire to its members.
The Montreal Centre has plans under way for two or more field stations in the
Province of Quebec. In addition, individual members of other Centres - Toronto,
Hamilton, Niagara Falls, Ottawa and Halifax - have expressed their intenticn of
viewing the eclipse from locations In Quebec or Maine.

    We would like to hear about your plans as they develop. Suggestions for the
observation programme are still welcome. We especially want to know about any
special projects you are undertaking.

    Additional copies of this bulletin are available on request.
