Limb Spicules from the Ground and from Space (2009)
Pasachoff, Jay M., Jacobson, William A., Sterling, Alphonse C.
We amassed statistics for quiet-sun chromosphere spicules at the limb using ground-based observations from the Swedish 1-m Solar Telescope on La Palma and simultaneously from NASA's Transition Region...
The 2008 August 1 Eclipse Solar-Minimum Corona Unraveled (2009)
Pasachoff, Jay M., Rusin, Vojtech, Druckmuller, Miloslav, Aniol, Peter, Saniga, Metod, Minarovjech, Milan
We discuss results stemming from observations of the white-light and [Fe XIV] emission corona during the total eclipse of the Sun of 2008 August 1, in Mongolia (Altaj region) and in Russia...
Solar eclipses as an astrophysical laboratory (2009)
Observations of the Sun during total eclipses have led to major discoveries, such as the existence of helium (from its spectrum), the high temperature of the corona (though the reason for the high...
Scientic observations at total solar eclipses (2009)
The occasion of the longest totality of an eclipse in the 18 yr 11⅓ d saros cycle leads to taking stock of the scientific value of ground-based eclipse observations in this space age. Though a...
Observing the solar corona with a tunable Fabry-Perot filter (2008)
Noble, Matthew W., Rust, David M., Bernasconi, Pietro N., Pasachoff, Jay M., Babcock, Bryce A., Bruck, Megan A.
A solid Fabry-Perot etalon with a 0.16 Å passband was used during the 180 s solar eclipse of 2006 for rapid scans of an emission line of the solar corona. The etalon was a Y-cut lithium niobate...
doi:10.1017/S1743921305001420 The black-drop effect explained (2008)
D. W. Kurtz, Jay M. Pasachoff, Glenn Schneider, Leon Golub
Abstract. The black-drop effect bedeviled attempts to determine the Astronomical Unit from the time of the transit of Venus of 1761, until dynamical determinations of the AU obviated the need for...
Further Observations at the Interstellar Deuterium Frequency, (2005)
Cesarsky,Diego A., Pasachoff,Jay M.
The authors repeated observations of the galactic center in the vicinity of the deuterium ground-state hyperfine transition at 327 MHz. In this year's observations, they tried to use a wider...
and the Black Drop effect: considerations for the 2004 transit of Venus (2003)
Glenn Schneider, Jay M. Pasachoff, Leon Golub C
Historically, the visual manifestation of the “Black Drop effect, ” the appearance of a band linking the solar limb to the disk of a transiting planet near the point of internal tangency, had...
Glenn Schneider, Jay M. Pasachoff, Leon Golub
Abstract. Transits of Mercury and Venus across the face of the Sun are rare. The 20th century had 15 transits of Mercury and the 21st century will have 14, the two most recent occuring on 15 November...

Short-Period Waves That Heat the Corona Detected at the 1999 Eclipse (2002)
Pasachoff, Jay M., Babcock, Bryce A., Russell, Kevin D., Seaton, Daniel B.
As a part of a study of the cause of solar coronal heating, we searched for high-frequency (~1 Hz) intensity oscillations in coronal loops in the [Fe XIV] coronal green line. We summarize results...
Cesarsky,Diego A., Moffet,Alan T., Pasachoff,Jay M.
The authors observed the spectrum of radiation from the spectrum of radiation from the galactic center in the vicinity of the deuterium ground-state hyperfine transition. With about 100 hours of...

Preliminary Report: 1980 Eclipse Coronal Oscillations Experiment (1980)
Pasachoff, Jay. M, Landman, Donald. A
We searched for short period (1 second) brightness oscillations in coronal loops during the 1980 total solar eclipse using cooled photomultipliers and digital microprocessor data handling and...
