Lowell Observatory, Wednesday, Sept. 4, 2019

We visited the Lowell Observatory before, probably at least ten years ago.  We stayed in hotel in Flagstaff and Lowell was one of the places we explored.  After parking, we were greeted by this colorful creature (I think it is a mountain lion, as the shape reminds me of the mountain lion we saw last month in Gila, NM).

 


This time, we went into the visitor center and started with the Lowell Tour.  "Explore Lowell Observatory’s past and present research efforts during this 45-minute guided walking tour of the historical campus. This tour includes a stop at the renowned 24” Clark Refracting Telescope, built in 1896 and still in use today."  The tour leader spent about 15 minutes in the auditorium telling us about Percival Lowell and his family.  Among other things, his sister Amy was a Pulitzer Prize winning poet and his younger brother Abbot went on to become President of Harvard University.  Here is a short bio about Percival Lowell, 1855 - 1916, copied from the observatory's website:

Percival Lowell was a mathematician, businessman, travel writer, and astronomer. The Lowell observatory in Arizona was the first permanent observatory built solely for its viewing conditions: high altitude to minimize atmospheric distortion, minimal cloud cover, and remote from the light pollution and smoke of cities.

Lowell discovered an enormous network of canals and oases on Mars, from which he deduced the existence of an advanced Martian civilization. Later studies by astronomers with larger telescopes found no canals and no oases. The canals were an illusion – Lowell’s aspirations led him to ‘see’ a landscape his telescopes lacked the power to resolve. However, he was not the only astronomer to see canals on Mars!

Early triumphs for the Lowell Observatory were the discovery of galactic redshifts, hinting at an expanding universe, and the discovery of the rotation of spiral galaxies.

Lowell’s search for a ninth planet, he called it Planet X, led to the discovery of Pluto.

We then headed out where our first stop was the Lampland Telescope, named for Carl Lampland.

Lampland spent his entire 50-year career as an astronomer at Lowell Observatory, participating in many important research projects including the search for a 9th planet that led to the discovery of Pluto and measuring the temperature of planets. He also kept a daily diary, which today serves as a valuable resource for documenting both research and personal activities around the observatory. Yet his name is not well remembered even in scientific circles.



Then it was on to the famous Clark Telescope built in 1894, recently renovated and still functional today, and is used for viewing on evening tours.



This is chair where you sit to look through the telescope.



Outside the Clark Telescope, there is a spot to view downtown Flagstaff.


After Lowell died, his wife had a mausoleum built.  The inner windows are blue (they are protected by the clear exterior windows) so that Lowell will looking up at the blue night sky for eternity.






The original water tower is near by (and they have to warn people not to climb on it).



The John Vickers McAllister telescope is also nearby and can be seen through the windows (the tour did not go inside).
 

After a short break we went on the Story of Pluto Tour starting in the Rotunda Museum.  The wings of the building are not open to the public, as they house offices for the many astronomers who still work here.  The Rotunda Museum is housed in this magnificent old building.



In the middle of the domed room is a large ball which is actually a screen on which the tour leader projected numerous things to help us better understand how Pluto (with its five moons) was discovered.







We then set out on the walk that demonstrated the distances in our solar system, staring with the sun and ending with Pluto and the telescope used to discover Pluto.






Outside, there is a statue of Clyde William Tombaugh - his observations of changes on slides were the actual discovery of Pluto.



As we were leaving, we passed by the new Giovale Open Deck Discovery.  We became members of the Lowell Observatory and have tickets to a members only event coming up in a couple of weeks from when I wrote this post.

A week in Phoenix and our first week in Munds Park, AZ, Aug. 19 - Sep. 1, 2019

On Monday Aug. 19, we had an uneventful trip from Gila, NM, back to our condo in Phoenix.  Since the central air conditioning system was still out, we installed a portable a/c unit in the living room.  While it was only rated to cool 500 square feet, it did a most acceptable job of making us comfortable.


Tuesday, Howard Air Company employees came and spent the day removing and replacing our central air system.  The unit from the roof top really showed its age - our condos were built in 1997 and those roof top units have been exposed to the sun and weather for 22 years.  I am surprised it lasted as long as it did.  As it turns out, ours is one of three units that were replaced in August and we saw at least one other condo using a portable a/c unit similar to ours in the photo above.

The new central air kept us cool and comfortable Tuesday evening and Wednesday - but then it died Thursday morning.  The installer told me that he installed a kill switch because he worried about the existing drain to which he connected the new system.  The drain clogged and the system shut down.  A Howard Air technician came and used compressed nitrogen to unclog the drain, and we were cool until we left on Monday the 26th.

The new system has an internet accessible digital thermostat.  As I write this post, I can see that the outside temp in Phoenix is 106 degrees, the inside temp is 82 degrees and the system is off.  When we return, I can turn the system on before we get there and the condo will be comfortably cool we arrive.


I got the car serviced Wednesday, we had dinner with Anne and Shawn Thursday, got shots and blood work for the dog Thursday, Patty and I got a variety of shots Friday, and Saturday evening I did a shift at the Desert Botanical Garden's Flashlight Tours.

Monday afternoon, the 26th, we drove to our rental in Munds Park, AZ.  The house is a very comfortable two bedroom, two bathroom home with a portable air conditioner in the kitchen, living room, dining room area.  It is more than adequate to keep us comfortable for the few hours on the few days where it is hot in the afternoon.  There is a back porch with gas grill and front porch with seating for six.



There are steps from the driveway up to the front porch, so we have put the dog's ramp there to make it easier to get up and down.  This is the ramp we use to get the dog into and out of the back of our SUV.


We have seen many beautiful sunsets from the street in front of the rental.



Thursday the 28th, before shopping, we had a picnic lunch at Bushmaster Park in Flagstaff.



Friday the 30th, we went into Flagstaff to see the movie "Where'd You Go, Bernadette?"  This was a very enjoyable movie, especially with all the discussion and photos of Antarctica - they were all things we recognized because of all we have learned from Megan working at McMurdo.


Saturday, we went to the Munds Park Farmers Market - there was only one vendor with fresh veggies, about ten food trucks and fifteen vendors with arts and crafts for sale.  While it was a disappointment, I did walk there and back for exercise (9,100 steps, 4.5 miles).  Sunday the 1st, we went to the Flagstaff Farmers Market.  There was a nice xeriscape garden that we explored before going to the market.




There were dozens of food vendors.  We started with lattes and pastries which we consumed while sitting at the Flagstaff Library, then bought fresh corn, red potatoes, a purple onion, a green pepper, peaches and apples.  We were surprised to see a vendor with fresh salmon from Alaska.


In the park one block away, there was Art in the Park with close to a hundred vendors.




Then it was a quick run to Safeway, a visit to some homes that were on sale and back to our rental in Munds Park for a quiet Sunday afternoon.
