“Compensation of the director for lowell observatory is determined by the sole trustee of the corporation after review of information provided by the human resource administrator and members of the advisory board and lowell observatory foundation who have experience in the research industry or compensation at non-profits. The human resource administrator reviews the total compensation of the director in accordance with regulations/guidelines established by the irs and industry best practices. Data regarding salaries of other directors (ceos) at organizations of similar size, including both non-profit and for-profit companies is also reviewed. The sole trustee, with advice from the advisory board, also establishes goals and objectives for the director and evaluates the performance of the director based on the prior year's goals and objectives.”
“When requested, documents regarding the observatory are provided by the business office. The 990 and audited financial statements are available on the lowell observatory website. The 990 is also available on guidestar and charity navigator. A summary of the consolidated financial statements is published annually in an annual report.”
“The endowment funds are used for support of lowell observatory and for reinvestment.”
“The following disclosure is related to the combined financial statements of the lowell observatory, trust u/w of percival lowell, and the lowell observatory foundation: the observatory, the foundation, and the trust are exempt from income taxes under both internal revenue code (irc) section 501(c)(3) and arizona income tax laws. The observatory is classified as other than a private foundation under irc section 509(a)(1). The foundation and the trust are each classified as other than a private foundation under irc section 509(a)(3) as a supporting organization of the observatory. Income from certain activities not directly related to the organization's tax-exempt purpose, however, may be subject to taxation as unrelated business taxable income (ubti).

| IRS990/Desc | 0 | CONTINUING A MORE THAN 125-YEAR-LONG LEGACY OF ASTRONOMICAL DISCOVERY, LOWELL OBSERVATORY ASTRONOMERS CONDUCTED FOREFRONT RESEARCH IN MANY AREAS OF ASTRONOMY - FROM THE SUN AND SOLAR SYSTEM TO EXOPLANETS, STARS, GALAXIES, AND COSMOLOGY. IN 2020, LOWELL ASTRONOMERS PUBLISHED MORE THAN 100 PEER-REVIEWED PAPERS IN LEADING SCIENTIFIC JOURNALS, ALONG WITH ANOTHER 75 PAPERS IN OTHER VENUES. THEY ALSO PARTICIPATED IN MAJOR SCIENTIFIC MISSIONS, USED WORLD-LEADING TELESCOPES ACROSS THE GLOBE AND IN SPACE, AND WERE ACTIVE IN EDUCATION AND PUBLIC OUTREACH. LOWELL ASTRONOMERS CONTINUE TO BE VERY SUCCESSFUL AT OBTAINING GRANTS IN SUPPORT OF THEIR RESEARCH FROM NASA, THE NATIONAL SCIENCE FOUNDATION, AND OTHER AGENCIES. THE 4.3-METER LOWELL DISCOVERY TELESCOPE (LDT) DELIVERED APPROXIMATELY 250 SCIENCE NIGHTS -- LOSING ONLY 50 NIGHTS TO SHUTDOWNS DUE TO THE COVID-19 PANDEMIC (SIGNIFICANTLY BETTER THAN MANY OTHER COMPARABLE FACILITIES, SOME OF WHICH HAVE STILL NOT RETURNED TO FULL OPERATION). THESE SCIENCE NIGHTS WERE USED BY LOWELL STAFF, AS WELL AS ASTRONOMERS AT OUR PARTNER INSTITUTIONS: BOSTON UNIVERSITY, NORTHERN ARIZONA UNIVERSITY, UNIVERSITY OF MARYLAND, UNIVERSITY OF TOLEDO, AND YALE UNIVERSITY. IN TOTAL, LDT FEATURED PROMINENTLY IN MORE THAN THREE DOZEN SCIENTIFIC OR TECHNICAL PUBLICATIONS IN 2020. LDT'S GROWING SUITE OF STATE-OF-THE-ART INSTRUMENTS, SUCH AS THE NEW HIGH-PRECISION SPECTROGRAPH EXPRES, ENABLE CUTTING EDGE RESEARCH ACROSS MULTIPLE FIELDS, INCLUDING THE SEARCH FOR EXOPLANETS. IN PARTNERSHIP WITH THE US NAVAL OBSERVATORY AND THE NAVAL RESEARCH LABORATORY, LOWELL HAS BEGUN A MULTI-MILLION DOLLAR UPGRADE OF THE NAVY PRECISION OPTICAL INTERFEROMETER (NPOI) THAT WILL ADD THREE ONE-METER TELESCOPES TO THE EXISTING ARRAY AND COMPLETE OTHER CRITICAL MAINTENANCE AND UPGRADES, GREATLY INCREASING THE SCIENTIFIC PERFORMANCE OF THAT SITE. LOWELL OBSERVATORY ALSO CONTINUED TO OPERATE OTHER SMALLER TELESCOPES AT ITS ANDERSON MESA SITE, AND HAS BEGUN LAYING THE GROUNDWORK FOR THE REPLACEMENT OF ITS ANTIQUATED 31" TELESCOPE WITH A MODERN 1M TELESCOPE. ACCESS TO LOCAL TELESCOPES EQUIPPED WITH WORLD-CLASS INSTRUMENTS HAS ENABLED SCIENCE THAT COULD NOT BE DONE ELSEWHERE. IN ADDITION, THE OBSERVATORY IS UNDERTAKING A DRAMATIC EXPANSION OF ITS MAIN CAMPUS ON MARS HILL, INCLUDING PRELIMINARY DESIGN WORK FOR A NEW TECHNICAL SERVICES BUILDING THAT WILL GREATLY INCREASE THE INSTRUMENTATION AND ENGINEERING CAPABILITIES OF ITS TECHNICAL STAFF. |

WORKING IN COLLABORATION WITH THE MARKETING AND COMMUNICATIONS DEPARTMENT, THE OUTREACH TEAM WAS ABLE TO CONTINUE OFFERING PROGRAMS THROUGH DIGITAL MEANS. THESE PROGRAMS INCLUDED RECURRING LIVESTREAMS SUCH AS INTERACTIVE STARGAZING, THE MARS HILL ALMANAC, AND SAGAS IN THE SKY, AS WELL AS PROGRAMS FOR SPECIAL CELESTIAL OCCASIONS SUCH AS PLANETARY OPPOSITIONS, LUNAR ECLIPSES, AND CONJUNCTIONS. BEGINNING IN AUGUST, LOWELL WELCOMED GUESTS BACK TO MARS HILL FOR PREMIUM ACCESS PROGRAMS AT THE GIOVALE OPEN DECK OBSERVATORY. THE PUBLIC PROGRAM SUPERVISOR TEAM DEVELOPED A CREATIVE PROGRAM THAT ALLOWED FOR A SOLELY OUTDOOR EXPERIENCE TO MINIMIZE RISK OF TRANSMISSION. THESE PROGRAMS WERE EXTREMELY WELL RECEIVED BY GUESTS. THE PRIVACY OF A SINGLE GROUP AT A TELESCOPE FACILITY ALLOWED EDUCATORS TO TAILOR EACH EXPERIENCE TO THE GUESTS' ASTRONOMY BACKGROUND AND AREAS OF INTEREST. IN SEPTEMBER, THE PUBLIC PROGRAM WELCOMED ITS NEWEST TELESCOPE: THE DYER TELESCOPE, A 24" PLANEWAVE MOUNTED INSIDE A NEWLY REFURBISHED DOME. THIS TELESCOPE PROVIDED THE OUTREACH TEAM WITH ANOTHER VENUE IN WHICH TO HOLD INTIMATE AND PERSONALIZED PREMIUM ACCESS PROGRAMS. IN DECEMBER, THE PLANETS JUPITER AND SATURN DRIFTED CLOSER TOGETHER IN THE SKY THAN THEY HAVE BEEN IN CENTURIES, AND THE WHOLE WORLD TURNED ITS EYES ON THE GREAT CONJUNCTION. IN ADDITION TO THE LARGEST LIVESTREAM TO DATE, THE PUBLIC PROGRAM DEVELOPED SPECIAL PROGRAMMING TO ALLOW DOZENS OF GUESTS TO VIEW THE GREAT CONJUNCTION FROM OUR GODO AND DYER TELESCOPES. |
