Lowell Observatory Archival Material August 6, 2013 In our paper, ‘Revisiting The 1963 Aristarchus Events’1, Anthony Cook and I relied heavily on documents in the Lowell Observatory Archive. We wish to thank Lowell Observatory Director Jeffrey Hall for granting us permission to post the following documents on our web site and in particular, we extend a heartfelt “Thank You” to Lowell Observatory Librarian/Archivist Lauren Amundson for her diligence in supplying us with the 305 pages of material in this document as they were being catalogued. This document contains all correspondence and related material concerning ‘The 1963 Aristarchus Events’ 2 identified in the Lowell Observatory Archives catalogued as of late 2012. This PDF file was constructed with PDF Converter Professional 7 and should also be readable with standard PDF software packages. Original scanned Lowell images were converted to PDF format and then MRC compression with text search option was applied allowing full search capabilities. For example, a PDF search of “Greenacre” should return 98 results including those on this page. This document is organized by grouping together all letters and documents sent between correspondents ordered chronologically within each grouping. For example, the first grouping of correspondence contains all letters in the Lowell Archive sent between Dr. John S. Hall and William D. Cannell starting with the earliest exchange on November 14, 1960 and continuing chronologically to the last relevant document on July 5, 1967, which was a Hall reference letter for Cannell. Some sections are simply newspaper articles or other documents placed in chronological order between correspondence groupings. There are no section headings as all documents are in a continuous flow. We hope this material is useful to fellow researchers. Kind Regards, Bob O’Connell, Keystone Heights, Florida August 6, 2013 Note: All material courtesy of the Lowell Observatory Archives.

November 14, 1960 Mr. William Cannell Headquarters Aeronautical Chart and Information Center United States Air Force Second and Arsenal St. Louis 18, Missouri Dear Bill: Just a note to say that we forwarded a proposal and also an answer to the questionnaire on November -. I hope that both are satisfactory from your point of view. The visual tailpiece of the 24-inch telescope is now in the shop. Several minor improvements are being nade on this and on your plot- ting board. I am also having my 16 mm magazine-type motion picture camera arranged so that it may be swivelled into position in place of the eye piece. This camera has film speeds of 16, 24, 32, and 64 frames per second. At the moment I have a magazine of Koda- chrome to try. I do not, however, think that it is sufficiently fast to do much good. Also, according to E. C. Slipher, Kodachrome is inherently grainey. An investigation of available sheet film indicates that Ortho X, Ortho press, and Verichrome with daylight speeds of 125, 100, and 64 might be useful for getting large amounts of information in a short time. A special emulsion designed for spectroscopic work type II-G appears to be ideal. All of these emulsions lose their sensitivity at the red end before out of focus troubles are en- countered. Of course the blue light would be eliminated by a fil- ter. I wonder if you would want to see if there is not an emulsion similar to these which would be available in 16 mm sizes for your work? The work is progressing at the old shcp, and it looks as if it will be habitable soon after your arrival on the 25th. The old driving mechanism has been removed from the 24-inch done and several groups are fabricating the necessary steel and woodwork required to remount the dome. If any seriaus hitch occurs, we will let you know at once. Sincerely yours, John S. Hall jetlipat All material courtesy Lowell Observatory Archives.

LOUIS 18, MISSOURI REPLY TO ATTN OF: ACDCS 12 January 1961 SUBJECT: TDY to Lowell Observatory TO: Dr. John Hall Lowell Observatory Flagstaff, Arizona Dear Dr. Hall, It seems a long time since we last communicated but I wanted to have something concrete to report in this letter. I will be coming to Flagstaff on the 22nd of January and staying until the 2nd of February. I expect to be coming alone on this trip. We are planning a similar trip for the last two weeks in February, with perhaps one or two more people. Travel and program monies are still a bit unstable which is the reason for limiting the number of people on the trips and the length of stay. We expect the lunar program to stabilize by the first of the coming fiscal year and therefore must operate on a limited basis until that time. Evenso we will be seeking a 4 month contract with you to extend our observation time from 1 March thru 30 June. Money for contracting is in a separate funding category, and there appears to be no problem in that area. Many things have happened here during the last two months regarding our lunar work. Welve had heartbreaking difficulties as well as joyous successes. To begin, we had bad luck printing the Kepler Chart just before Bob Carder was to take it to Lenningrad for the big show. Half the relief did not print, and the color was nauseating. This was a setback for all of us particularly for Bob because he had hoped to advertize our work by passing out quantities of the chart. His trip was successful however, even without the printed chart because he had made good lantern slides. In the meantime we corrected the printing errors on the Kepler Chart and obtained the quality print that we originally expected. The colors are excellent and all of the relief printed. You will find a copy enclosed. All material courtesy Lowell Observatory Archives. Any public use of this material requires written permission from Lowell Observatory. On 30 December 1960 I gave a 15 "minute paper on "USAF Lunar Cartography" at the AAAS Meeting in New York City. Fortunately I was able to pass out over 100 copies of the Kepler chart which the selenologists seemed to appreciate. We have been receiving considerable publicity from all of this activity. Bob Carder was interviewed on a television news cast about his paper delivered in Lenningrad. Following this, Bob Carder, Jim Picariello (our model maker) and myself were inter- viewed on another television news program about our lunar charts and models. I told the public that we relied on telescopic observations at Lowell Observatory for making these lunar charts the best possible. In addition to this, we have been receiving write-ups in newspapers and magazines all over the country. So much for what has happened here. I suppose things have been buzzing at Lowell also. You probably have very cold weather there by now and I intend to bring some cold-weather clothing with me this time. I am still planning to bring 8 magazines (50 ft. per mag) of 16mm movie film. That is 4 magazines of plus-X and 4 magazines of Tri-X. Also I will bring about 24 3 1/4 x 4 1/4 glass plates with Royal Pan X emulsion. That is the best I can do on film at this time. Perhaps I can do better after I talk with you again. I should be arriving in Flagstaff on Sunday night, 22 Jan., by government vehicle as I did before. Don't worry about a hotel reservation for me because I plan to try a motel this time in an effort to get a cheaper rate. I won't plan to see you that Sunday night. If it is convenient for you, I would like to see you at 9:00 AM the next morning. Should anything happen to my plans, I will let you know at once. Sincerely, 6:et William D. Cannell 2 All material courtesy Lowell Observatory Archives. Any public use of this material requires written permission from Lowell Observatory.

LOUIS 18, MISSOURI REPLY TO ATTN OF: ACDCS 18 January 1961 SUBJECT: TO: Dr. John Hall Lowell Observatory Flagstaff, Arizona Dear Dr. Hall Just a line to let you know of a slight change in previous plans. Bob Carder told me about your call to ACIC and your offer to help in our bind on funds was well received. However, things had begun to relax already which Bob may have mentioned to you. There will be two of us making the trip this time.
