Analysis of Short-term Solar Activity Variability and Estimating the Timings of the Next Enhanced Bursts
Juie Shetye, Mausumi Dikpati
We present a hybrid forecasting strategy that combines numerical modeling, statistical forecasting, and machine learning methods to predict enhanced bursts of solar activity. These…
Compact Ca II K Brightenings Precede Solar Flares: A Dunn Solar Telescope Pilot Study
Aman Priyadarshi M. Kumar, Juie Shetye, Sean G. Sellers +1
We present a uniform analysis of compact Ca II K (3934 Å) brightenings that occur near flare kernels and assess their value as short-lead indicators of solar flare onset. Using hig…
First High-Resolution Observations of Chromospheric Swirls with the Dunn Solar Telescope
Oana Vesa, Juie Shetye, Erwin Verwichte
We present the first observations of chromospheric swirls using the Hydrogen-alpha Rapid Dynamics camera and Rapid Oscillations in the Solar Atmosphere imaging instruments at the D…
The Sunspot Solar Observatory Data Archive: Continuing Operations at the Dunn Solar Telescope
Sean G. Sellers, Juie Shetye, Damian J. Christian +9
The Sunspot Solar Observatory Data Archive (SSODA) stores data acquired with the suite of instruments at the Richard B. Dunn Solar Telescope (DST) from February 2018 to the present…
Searching for signatures of H spicule-like features in the solar transition region
Nived Vilangot Nhalil, Juie Shetye, J. Gerry Doyle
New instrumental and telescopes covering the optical and ultra-violet spectral regions have revealed a range of small-scale dynamic features, many which may be related. For example…
Detection of spicules termed Rapid Blue-shifted Excursions as seen in the chromosphere via Hα and the transition region via Si iv 1394 Å line emission
Nived Vilangot Nhalil, Juie Shetye, J. Gerry Doyle
We show signatures of spicules termed Rapid Blue-shifted Excursions (RBEs) in the Si iv 1394 Å emission line using a semi-automated detection approach. We use the Hα filtergrams ob…
The Nature of High-frequency Oscillations Associated with Short-lived Spicule-type Events
Juie Shetye, Erwin Verwichte, Marco Stangalini +1
We investigate high resolution spectroscopic and imaging observations from the CRisp Imaging SpectroPolarimeter (CRISP) instrument to study the dynamics of chromospheric spicule ty…
Unveiling the magnetic nature of chromospheric vortices
Mariarita Murabito, Juie Shetye, Marco Stangalini +5
Vortex structures in the Sun's chromosphere are believed to channel energy between different layers of the solar atmosphere. We investigate the nature and dynamics of two small-sca…
Signatures of quiet Sun reconnection events in Ca~{\sc ii}, H and Fe~{\sc i}
J. Shetye, S. Shelyag, A. L. Reid +3
We use observations of quiet Sun (QS) regions in the H 6563 Å, Ca~{\sc ii} 8542 Å\, and Fe~{\sc i} 6302 Å lines. We observe brightenings in the wings of the H and Ca~{\sc ii}…
High--cadence observations of spicular-type events on the Sun
J. Shetye, J. G. Doyle, E. Scullion +5
Chromospheric observations taken at high cadence and high spatial resolution show a range of spicule like features, including Type I, Type II (as well as RBEs and RREs) and those w…
Observations and modelling of North-South asymmetries using a Flux Transport Dynamo
Juie Shetye, Durgesh Tripathi, Mausumi Dikpati
The peculiar behaviour of the solar cycle 23 and its prolonged minima has been one of the most studied problems over the last few years. In the present paper, we study the asymmetr…
A coronal wave and an asymmetric eruptive filament in SUMER, CDS, EIT, and TRACE co-observations
M. S. Madjarska, J. G. Doyle, J. Shetye
The objectives of the present study is to provide a better physical understanding of the complex inter-relation and evolution of several solar coronal features comprising a double-…
