Solar Rotation Measurements at Mount Wilson over the Period 1990–1995
One of the most fundamental properties of the Sun is its rate of rotation. Kinetic energy of large-scale circulation might interact with rotation and cause the surface rate to vary throughout the solar cycle. The solar wind carries off angular momentum from the Sun, and the coupling between the outer and inner parts of the heliosphere might produce effects that are evident in the photosphere an...
متن کاملMultispectral analysis of Asteroid 3 Juno taken with the 100-inch telescope at Mount Wilson Observatory
High-resolution multispectral images of main-belt asteroid 3 Juno were taken at visible and near-IR wavelengths with the 100-inch telescope at Mount Wilson Observatory equipped with an adaptive optics system. The images show spectral features that may represent a large relatively recent impact that deeply excavated the coarse-grained olivine–pyroxene-rich crust of the asteroid. © 2003 Elsevier ...
متن کاملMapping CH4 :CO2 ratios in Los Angeles with CLARS-FTS from Mount Wilson, California
The Los Angeles megacity, which is home to more than 40% of the population in California, is the second largest megacity in the United States and an intense source of anthropogenic greenhouse gases (GHGs). Quantifying GHG emissions from the megacity and monitoring their spatiotemporal trends are essential to be able to understand the effectiveness of emission control policies. Here we measure c...
متن کاملAdaptive Optics Observations of Arcturus using the Mount Wilson 100-inch Telescope
Upon inspection of the multiple star results in the HIPPARCOS catalog (European Space Agency, 1997), the flag for entry number 69673 particularly stands out; it is Arcturus, for which no companion has been reported previously. The HIPPARCOS companion is reported to be at a separation of 0.255± 0.039 arcsec with a magnitude difference in a broadband filter (peaked near 460 nm) of 3.33 ± 0.31. We...
متن کاملModeling Total Solar Irradiance Variations Using Automated Classification Software On Mount Wilson Data Solar Physics
We present the results using the AutoClass analysis application available at NASA/Ames Intelligent Systems Div. (2002) which is a Bayesian, finite mixture model classification system developed by Cheeseman and Stutz (1996) . We apply this system to Mount Wilson Solar Observatory (MWO) intensity and magnetogram images and classify individual pixels on the solar surface to calculate daily indices...
