  • Glossary Glossary
    Glossary Glossary Albedo A measure of an object’s reflectivity. A pure white reflecting surface has an albedo of 1.0 (100%). A pitch-black, nonreflecting surface has an albedo of 0.0. The Moon is a fairly dark object with a combined albedo of 0.07 (reflecting 7% of the sunlight that falls upon it). The albedo range of the lunar maria is between 0.05 and 0.08. The brighter highlands have an albedo range from 0.09 to 0.15. Anorthosite Rocks rich in the mineral feldspar, making up much of the Moon’s bright highland regions. Aperture The diameter of a telescope’s objective lens or primary mirror. Apogee The point in the Moon’s orbit where it is furthest from the Earth. At apogee, the Moon can reach a maximum distance of 406,700 km from the Earth. Apollo The manned lunar program of the United States. Between July 1969 and December 1972, six Apollo missions landed on the Moon, allowing a total of 12 astronauts to explore its surface. Asteroid A minor planet. A large solid body of rock in orbit around the Sun. Banded crater A crater that displays dusky linear tracts on its inner walls and/or floor. 250 Basalt A dark, fine-grained volcanic rock, low in silicon, with a low viscosity. Basaltic material fills many of the Moon’s major basins, especially on the near side. Glossary Basin A very large circular impact structure (usually comprising multiple concentric rings) that usually displays some degree of flooding with lava. The largest and most conspicuous lava- flooded basins on the Moon are found on the near side, and most are filled to their outer edges with mare basalts.

  • 2020–21 Commencement Program
    Commencement UNIVERSITY OF COLORADO BOULDER MAY 6, 2021 One Hundred Forty-Fifth Year of the University NORLIN CHARGE TO THE GRADUATES The first commencement at the University of Colorado was held for six graduates on June 8, 1882, in the chapel of Old Main. It was not until 40 years later, on September 4, 1922, that the first summer commencement was held. Since the first commencement in 1882, the University of Colorado Boulder has awarded more than 350,000 degrees. The traditional Norlin Charge to the graduates was first read by President George Norlin to the June 1935 graduating class. You are now certified to the world at large as alumni of the university. She is your kindly mother and you her cherished sons and daughters. This exercise denotes not your severance from her, but your union with her. Commencement does not mean, as many wrongly think, the breaking of ties and the beginning of life apart. Rather it marks your initiation in the fullest sense into the fellowship of the university, as bearers of her torch, as centers of her influence, as promoters of her spirit. The university is not the campus, not the buildings on campus, not the faculties, not the students of any one time—not one of these or all of them. The university consists of all who come into and go forth from her halls, who are touched by her influence, and who carry on her spirit. Wherever you go, the university goes with you. Wherever you are at work, there is the university at work.

  • Summary of Sexual Abuse Claims in Chapter 11 Cases of Boy Scouts of America
    Summary of Sexual Abuse Claims in Chapter 11 Cases of Boy Scouts of America There are approximately 101,135sexual abuse claims filed. Of those claims, the Tort Claimants’ Committee estimates that there are approximately 83,807 unique claims if the amended and superseded and multiple claims filed on account of the same survivor are removed. The summary of sexual abuse claims below uses the set of 83,807 of claim for purposes of claims summary below.1 The Tort Claimants’ Committee has broken down the sexual abuse claims in various categories for the purpose of disclosing where and when the sexual abuse claims arose and the identity of certain of the parties that are implicated in the alleged sexual abuse. Attached hereto as Exhibit 1 is a chart that shows the sexual abuse claims broken down by the year in which they first arose. Please note that there approximately 10,500 claims did not provide a date for when the sexual abuse occurred. As a result, those claims have not been assigned a year in which the abuse first arose. Attached hereto as Exhibit 2 is a chart that shows the claims broken down by the state or jurisdiction in which they arose. Please note there are approximately 7,186 claims that did not provide a location of abuse. Those claims are reflected by YY or ZZ in the codes used to identify the applicable state or jurisdiction. Those claims have not been assigned a state or other jurisdiction. Attached hereto as Exhibit 3 is a chart that shows the claims broken down by the Local Council implicated in the sexual abuse.

  • Lunar Club Observations
    Guys & Gals, Here, belatedly, is my Christmas present to you. I couldn’t buy each of you a lunar map, so I did the next best thing. Below this letter you’ll find a guide for observing each of the 100 lunar features on the A. L.’s Lunar Club observing list. My guide tells you what the features are, where they are located, what instrument (naked eyes, binoculars or telescope) will give you the best view of them and what you can expect to see when you find them. It may or may not look like it, but this project involved a massive amount of work. In preparing it, I relied heavily on three resources: *The lunar map I used to determine which quadrant of the Moon each feature resides in is the laminated Sky & Telescope Lunar Map – specifically, the one that shows the Moon as we see it naked-eye or in binoculars. (S&T also sells one with the features reversed to match the view in a refracting telescope for the same price.); and *The text consists of information from (a) my own observing notes and (b) material in Ernest Cherrington’s Exploring the Moon Through Binoculars and Small Telescopes. Both the map and Cherrington’s book were door prizes at our Dec. Christmas party. My goal, of course, is to get you interested in learning more about our nearest neighbor in space. The Moon is a fascinating and lovely place, and one that all too often is overlooked by amateur astronomers. But of all the objects in the night sky, the Moon is the most accessible and easiest to observe.
