This was due to the great efforts and tireless work of the Adler Planetarium staff, Dr. Joe Chamberlain, President, and a host of speakers including fellow planetarians that presented papers on every subject matter relating to the planetarium profession. It was at this 1980 convention that I read a letter addressed to you from the President of the United States of America, President Jimmy Carter, and it is also included in this journal. As I have stated before, Planetarians are unique. There is probably more diversified knowledge among planetarians than any other society and it is our goal to promote and increase the students' and the public's understanding of Astronomy, the Sciences and the Related Arts of Literature and Music and to give insight into the future of this, our fragile earth on which we live. It was during this convention that your President met great old friends and met an astonishing number of great new ones. If you felt that your President was tired and exhausted at times-then you saw it as it really was. Yet, at no time did he try to skip his obligated duties. He actually looked forward to them and he continues to do so. It was during this 1980 convention that your executive council received Dr. Henry King into Honorary membership into our society. There was also a constitutional change approved by the council concerning article II of our Constitution. You, the membership, will vote on this in the near future. There will be in the mail as this goes to press, an The nation of Mexico has a lot for it and a International Planetarium Society Special Survey lot to be proud of.

In one myth, Orion boasted he would kill all the wild animals on the earth. But, the earth goddess Gaia, who was the protector of all animals, produced a gigantic scorpion, whose body was so heavily encased that Orion was unable to pierce through the armour, and was himself stung to death. His companion Artemis was greatly saddened and arranged for Orion to be immortalised among the stars. Scorpius, the scorpion, was placed on the opposite side of the sky so that Orion would never be hurt by it again. To this day, Orion is never seen in the sky at the same time as Scorpius.

Goodale and Steven A. Harfenist Keene State College, Keene NH Abstract: Students calculated ephemerides and generated orbits of four well-known binary systems. Using an iterative technique in Microsoft® Excel® to solve Kepler's equation, separa- tion and position angle values were generated as well as plots of the apparent orbits. Current position angle and separation values were measured in the field and compared well to the calcu- lated values for the stars: STF1196AB,C, STF296AB, STF296AB and STF60AB. controller of the telescope and manually centered.

Forty five State College calculated tables of ephemerides and second exposures were taken with the telescope drive measured the separation and position angles of four turned off also at ISO 800. The long exposure produced binary stars. The ephemerides included separation a star trail as the pair drifted across the field, indicating position angle and year at which they occur. Values West.
