I love well-behaved spiders! They are, in fact, how most people find my site. Unfortunately, my network has a limited bandwidth and pictures take up bandwidth. Spiders ask for lots and lots of pages and chew up lots and lots of bandwidth which slows things down considerably for regular folk. To counter this, you'll see all the text on the page but the images are being suppressed. Also, some system options like merges are being blocked for you.
Note: Permission is NOT granted for spiders, robots, etc to use the site for AI-generation purposes. I'm sure you're thrilled by your ability to make revenue from my work but there's nothing in that for my human users or for me.
If you are in fact human, please email me at guthrie.bruce@gmail.com and I can check if your designation was made in error. Given your number of hits, that's unlikely but what the hell.

1. LOWELC_220715_022.JPG: Clark Dome Weather Station Understanding and predicting local weather patterns helps astronomers plan successful observing runs. Because of this, observatories such as Lowell typically maintain weather stations to monitor the conditions. One such station was set up at the Clark Telescope dome when it was permanently placed at this site in 1897. Instruments for the station were enclosed in an instrument shelter, which shielded thermometers, hygrometers (to monitor humidity), and other devices from the Sun, precipitation, and other sources of heat and light that could produce inaccurate readings. This type of shelter features downward-pointing louvers that allow for air flow while shielding the instruments from heat and light. This weather station was removed in the latter part of the 20th century, but a modern station is now mounted on top of the Clark Telescope dome. Can you see it? Look for the anemometer (for detecting wind speed), whose wind cups may be spinning.

Wikipedia Description: Lowell Observatory
From Wikipedia, the free encyclopedia

Lowell Observatory is an astronomical observatory in Flagstaff, Arizona, United States. Lowell Observatory was established in 1894, placing it among the oldest observatories in the United States, and was designated a National Historic Landmark in 1965. In 2011, the Observatory was named one of "The World's 100 Most Important Places" by Time Magazine. It was at the Lowell Observatory that the dwarf planet Pluto was discovered in 1930 by Clyde Tombaugh.
The observatory was founded by astronomer Percival Lowell of Boston's Lowell family and is overseen by a sole trustee, a position historically handed down through the family. The first trustee was Lowell's third cousin Guy Lowell (1916–1927). Percival's nephew Roger Putnam served from 1927 to 1967, followed by Roger's son Michael (1967–1987), Michael's brother William Lowell Putnam III (1987–2013), and current trustee W. Lowell Putnam.
Multiple astronauts attended the Lowell Observatory in 1963 while the moon was being mapped for the Apollo Program.
The observatory operates several telescopes at three locations in the Flagstaff area. The main facility, located on Mars Hill just west of downtown Flagstaff, houses the original 61-centimeter (24-inch) Clark Refracting Telescope, which is now used for public education, with 85,000 annual visitors. The telescope, built in 1896 for $20,000, was assembled in Boston by Alvan Clark & Sons and then shipped by train to Flagstaff. Also located on the Mars Hill campus is the 33-centimeter (13-inch) Pluto Discovery Telescope, used by Clyde Tombaugh in 1930 to discover the dwarf planet Pluto.
In 2014, the 8,000 square feet (740 m2) Putnam Center was opened. This observatory included many rooms with tools that were useful to observers including a library for research, a room for processing photographic glass plates, multiple antique instruments used by previous astronomers, and many artifacts. The observatory does contain areas that are closed to the public view, although there are multiple places that tourists are welcome to visit.
Lowell Observatory currently operates four research telescopes at its Anderson Mesa dark-sky site, located 20 km (12 mi) southeast of Flagstaff, including the 180-centimeter (72-inch) Perkins Telescope (in partnership with Boston University) and the 110-centimeter (42-inch) John S. Hall Telescope. Lowell is a partner with the United States Naval Observatory and Naval Research Laboratory in the Navy Precision Optical Interferometer (NPOI) also located at that site. The Observatory also operates smaller research telescopes at its historic site on Mars Hill and in Australia and Chile.
Past Anderson Mesa, on the peak of Happy Jack, Lowell Observatory built the 4.28-meter (169-inch) Lowell Discovery Telescope in partnership with Discovery Communications, Inc.

History

The observatory has carried out a wide array of research. One of its programs was the measurement of the variability of solar irradiance. When Harold L. Johnson took over as the director in 1952, the stated objective became to focus on light from the Sun reflecting from Uranus and Neptune. In 1953, the current 53 cm (21-inch) telescope was erected. Beginning in 1954, this telescope began monitoring the brightness of these two planets, and comparing these measurements with a reference set of Sun-like stars.
Self-taught astronomer Robert Burnham Jr. was an employee at Lowell observatory from 1958 – 1979, being known for his Celestial Handbook.
Beginning in 2012, Lowell Observatory began offering camps for children known as LOCKs (Lowell Observatory Camps for Kids). The first camp was established for elementary students. Later on, in 2013, they added an additional camp program for preschool children. The following year they added another program for middle school students. (“Kelly”, Manager at Lowell Observatory). Kids have the opportunity to learn hands-on about science, technology, engineering, and math (STEM) through a variety of activities that include games, experiments, story time, art, music, and more.
In 2016, Kevin Schindler published Lowell Observatory, a 128-page book containing over 200 captions and pictures. Arcadia Publishing’s Images of America included it in their series, which increased the enthusiasm of space in the public. The book itself features the popular reputation of Lowell Observatory, encompassing the revolutionary research of scientists and how they contributed to the field of astronomy.
Bigger photos? To save server space, the full-sized versions of these images have either not been loaded to the server or have been removed from the server. (Only some pages are loaded with full-sized images and those usually get removed after three months.) I still have them though. If you want me to email them to you, please send an email to guthrie.bruce@gmail.com and I can email them to you, or, depending on the number of images, just repost the page again will the full-sized images.
