Coronal Heating Rate in the Slow Solar Wind
Daniele Telloni, Marco Romoli, Marco Velli +59
This Letter reports the first observational estimate of the heating rate in the slowly expanding solar corona. The analysis exploits the simultaneous remote and local observations…
Does Turbulence along the Coronal Current Sheet Drive Ion Cyclotron Waves?
Daniele Telloni, Gary P. Zank, Laxman Adhikari +32
Evidence for the presence of ion cyclotron waves, driven by turbulence, at the boundaries of the current sheet is reported in this paper. By exploiting the full potential of the jo…
Defining the Middle Corona
Matthew J. West, Daniel B. Seaton, David B. Wexler +31
The middle corona, the region roughly spanning heliocentric altitudes from to , encompasses almost all of the influential physical transitions and processes that…
Ultraviolet Observations of Comet 96/P Machholz at Perihelion
J. C. Raymond, S. Giordano, S. Mancuso +2
Ultraviolet spectra of Comet 96/P Machholz were obtained during its 2002 perihelion with the UVCS instrument aboard the SOHO satellite. Emission from H I, C II, C III, and O I, is…
Exploring the Solar Wind from its Source on the Corona into the Inner Heliosphere during the First Solar Orbiter - Parker Solar Probe Quadrature
Daniele Telloni, Vincenzo Andretta, Ester Antonucci +68
This Letter addresses the first Solar Orbiter (SO) -- Parker Solar Probe (PSP) quadrature, occurring on January 18, 2021, to investigate the evolution of solar wind from the extend…
Effects of the chromospheric Lyα line profile shape on the determination of the solar wind HI outflow velocity using the Doppler dimming technique
G. E. Capuano, S. Dolei, D. Spadaro +15
The determination of solar wind outflow velocity is fundamental in order to probe the mechanisms of wind acceleration in the corona. We aim to study, via the Doppler dimming techni…
Combining White Light and UV Lyman-alpha Coronagraphic Images to determine the Solar Wind Speed: the Quick Inversion Method
Alessandro Bemporad, Silvio Giordano, Luca Zangrilli +1
This work focuses on the combination of White Light (WL) and UV (Ly-alpha) coronagraphic images to demonstrate the capability to measure the solar wind speed in the inner corona di…
Radio evidence for a shock wave reflected by a coronal hole
S. Mancuso, A. Bemporad, F. Frassati +4
We report the first unambiguous observational evidence in the radio range of the reflection of a coronal shock wave at the boundary of a coronal hole. The event occurred above an a…
First light observations of the solar wind in the outer corona with the Metis coronagraph
M. Romoli, E. Antonucci, V. Andretta +65
The investigation of the wind in the solar corona initiated with the observations of the resonantly scattered UV emission of the coronal plasma obtained with UVCS-SOHO, designed to…
SWELTO -- Space WEather Laboratory in Turin Observatory
A. Bemporad, L. Abbo, D. Barghini +20
SWELTO -- Space WEather Laboratory in Turin Observatory is a conceptual framework where new ideas for the analysis of space-based and ground-based data are developed and tested. Th…
First Determination of 2D Speed Distribution within the Bodies of Coronal Mass Ejections with Cross-Correlation Analysis
Beili Ying, Alessandro Bemporad, Silvio Giordano +5
The determination of the speed of Coronal Mass Ejections (CMEs) is usually done by tracking brighter features (such as the CME front and core) in visible light coronagraphic images…
Spatial Offsets in Flare-CME Current Sheets
John C. Raymond, Silvio Giordano, Angela Ciaravella
Magnetic reconnection plays an integral part in nearly all models of solar flares and coronal mass ejections (CMEs). The reconnection heats and accelerates the plasma, produces ene…
Plasma properties from the multi-wavelength analysis of the November 1st 2003 CME/shock event
Carlo Benna, Salvatore Mancuso, Silvio Giordano +1
The analysis of the spectral properties and dynamic evolution of a CME/shock event observed on November 1st 2003 in white-light by the LASCO coronagraph and in the ultraviolet by t…
Influence of projection effects on the observed differential rotation rate in the UV corona
Salvatore Mancuso, Silvio Giordano
Following previous investigations by Giordano and Mancuso [1] and Mancuso and Giordano [2, 3] on the differential rotation of the solar corona as obtained through the analysis of t…
Transition Region Emission from Solar Flares during the Impulsive Phase
H. Johnson, J. C. Raymond, N. A. Murphy +4
There are relatively few observations of UV emission during the impulsive phases of solar flares, so the nature of that emission is poorly known. Photons produced by solar flares c…
Identification of the Coronal Sources of the Fast Solar Wind
S. Giordano, E. Antonucci, G. Noci +2
The present spectroscopic study of the ultraviolet coronal emission in a polar hole, detected on April 6-9, 1996 with the Ultraviolet Coronagraph Spectrometer aboard the SOHO space…
