Expanded sun-look angle program

Computer program provides time history of sun aspect angles as seen from spacecraft and generates binary tape containing time history of position, velocity, and body attitude angles of vehicle in local horizontal, local vertical system. Program is written in FORTRAN 5 and SLEUTH 2 for Univac 1108 computer

Low-cost solar tracking system

Smaller heat-collector is moved to stay in focus with the sun, instead of moving reflector. Tracking can be controlled by storing data of predicted solar positions or by applying conventional sun-sensing devices to follow solar movement

The Solar Galactic Environment

Combined heliosphere-astronomical data and models enrich our understanding both of effects the solar galactic environment might have on the inner heliosphere, and of interstellar clouds. Present data suggest that FeII/DI increases toward the upwind direction of the cluster of interstellar clouds (CLIC) flowing past the Sun. Cloud kinematics and abundances suggest an origin related to a supershell around the Scorpius-Centaurus Association. The solar space trajectory indicates the Sun entered the CLIC gas relatively recently.Comment: 3rd Annual IGPP-UCR Astrophysics Conference: Physics of the Outer Heliosphere [AIP

The Logic of Spectacle c. 1970

This paper examines the site plan and theme exhibit of the Osaka Expo of 1970, together with a week-long protest staged in the Tower of the Sun, which was the main element of the Theme Exhibit. Attempts to communicate a critical account of contemporary society and so transform the visitor were undercut by the Expo's ability to accommodate diverse interests and investments and to account for almost anything that was exhibited or staged on site. The Expo thus suggests that we need to supplement our understanding of spectacle as communication with an analysis of spectacle as a system

Thermal heliotrope - A passive sun-tracker

Continuous sun tracking device consists of helical bimetallic coil and control mechanism. Coil produces torque and angular displacement with temperature change, and acts as device's driving element. Control mechanism, concentric shading mechanism containing bimetallic sensor coil, controls tracking rate and provides for reset cycle

Secondary reflectors for economical sun-tracking energy collection system: A concept

Mechanism is simpler and lower in cost because it moves heat-collector pipe to stay in focus with sun, instead of moving heavy reflectors
