D.H. MENZEL WILL LEAD BULAK ECLIPSE TRIP

Friday, June 19 will be like any other day in Cambridge, but not so in Ak-Bulak, Siberia, for to this little hamlet, 200 miles noth of the Caspian sea, scientific expeditions will come from all over the world to observe an eclipse of the sun. Harvard and M.I.T. are combining to send a joint expedition under the direction of Donald H. Menzel, associate professor of Astronomy.

Henry Hemmendinger '35, 1G., and Miss Henrietta Swope are the other members of the University who will sail on Wednesday, April 8 for Russia, where they will join Dr. B.P. Gerasimovic, Soviet scientist, in the journey to the field station set up by the Poulkova Observatory.

Double Program

A double program is planned by the Crimson forces, who will endeavor not only to fathom the spectra of the sun's atmosphere and take numerous photographs of the phenomena, but also to take along a group of graduate students under the direction of Harry R. Mimno '28, assistant professor of Physics, to make radio studies of the Kennely-Heavyside layer and its effect upon radio waves.

Total Eclipse

The eclipse, which will be total for two minutes, will be observed through the expedition's eight spectroscopes. The instruments are made of a new super-light "Dowmetal" and are donated by the Dow Chemical Company, Midland, Michigan. With these and the new coronal camera, Dr. Menzel, who observed the eclipse of May, 1932, from Freiburg, Germany, expects to gain much new material which will be the subject for his lectures to be given in August at the Summer School session.
