Onset of the Magnetic Explosion in Solar Flares and Coronal Mass Ejections
- R. Moore, A. Sterling, H. Hudson, J. Lemen
- Physics
- 10 May 2001
We present observations of the magnetic field configuration and its transformation in six solar eruptive events that show good agreement with the standard bipolar model for eruptive flares. The…
DICHOTOMY OF SOLAR CORONAL JETS: STANDARD JETS AND BLOWOUT JETS
- R. Moore, J. Cirtain, A. Sterling, D. Falconer

By examining many X-ray jets in Hinode/X-Ray Telescope coronal X-ray movies of the polar coronal holes, we found that there is a dichotomy of polar X-ray jets. About two thirds fit the standard…
Solar Spicules: A Review of Recent Models and Targets for Future Observations – (Invited Review)

- 1 September 2000
Since their discovery over 100 years ago, there have been many suggestions for the origin and development of solar spicules. Because the velocities of spicules are comparable to the sound and Alfvén…
Yohkoh SXT Observations of X-Ray “Dimming” Associated with a Halo Coronal Mass Ejection
- A. Sterling, H. Hudson
- Physics
- 6 November 1997
A sudden depletion or intensity "dimming" of the X-ray corona sometimes accompanies a solar eruptive flare or coronal mass ejection (CME). We have identified a dimming that occurred just prior to a…

Yohkoh observations of Fe XXVI X-ray line emission from solar flares
- C. Pike, K. Phillips, J. Dubau
- Physics
- 1 June 1996
We report on observations from the Bragg Crystal Spectrometer (BCS) on board the Japanese solar flare spacecraft Yohkoh showing Fe XXVI Ly alpha X-ray line emission at 1.78 Angstrom. Some 75 events…
SOHO EIT Observations of Extreme-Ultraviolet “Dimming” Associated with a Halo Coronal Mass Ejection
- D. Zarro, A. Sterling, B. Thompson, H. Hudson, N. Nitta
- Physics
- 25 June 1999
A solar flare was observed on 1997 April 7 with the Soft X-ray Telescope (SXT) on Yohkoh. The flare was associated with a "halo" coronal mass ejection (CME). The flaring region showed areas of…
Material Outflows from Coronal Intensity “Dimming Regions” during Coronal Mass Ejection Onset
- L. Harra, A. Sterling
- Physics
- 10 November 2001
One signature of expulsion of coronal mass ejections (CMEs) from the solar corona is the appearance of transient intensity dimmings in coronal images. These dimmings have generally been assumed to be…
Imaging and Spectroscopic Investigations of a Solar Coronal Wave: Properties of the Wave Front and Associated Erupting Material
- L. Harra, A. Sterling
- Physics
- 10 April 2003
Using spectral data from the Coronal Diagnostic Spectrometer (CDS) instrument on the Solar and Heliospheric Observatory spacecraft, we observe a coronal wave feature (often referred to as an EIT…
Limb Spicules from the Ground and from Space
- J. Pasachoff, W. A. Jacobson, A. Sterling
- Physics
- 31 August 2009
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…
