Observational methods for solar origin diagnostics of energetic protons
Rositsa Miteva
The aim of the present report is to outline the observational methods used to determine the solar origin - in terms of flares and coronal mass ejections (CMEs) - of the in situ obs…
Multi-Energy Proton Events and Geomagnetic Storms in Solar Cycles 23 and 24
Rositsa Miteva, Susan W. Samwel, Svetoslav Zabunov
Solar energetic protons (SEPs) in different energy channels from 10 to above 100 MeV are analyzed and their relationship to solar and geomagnetic activity is investigated. We perfo…
The use of astronomical data for satellite tracking
Rositsa Miteva, Nikola Antonov, Adrian Sonka
The study explored the usage of astronomical observations for the identification and tracking of artificial satellites. Spacecraft streaks on astronomical images are a growing issu…
A network for solar optical observations in Bulgaria
Rositsa Miteva, Pencho Markishki, Werner Pötzi +6
The report presents a new initiative for the development of a network of ground-based stations for solar observations in the optical range. Three separate locations in Bulgaria hav…
Comparative study between low and high energy SOHO/ERNE protons in solar cycle 23
Rositsa Miteva, Susan W. Samwel, Momchil Dechev
We present a comparison between low and high energy solar energetic protons (SEPs) as observed by the SOHO/ERNE high energy detector in solar cycle (SC) 23. Observed and corrected…
New Bulgarian-Austrian project 'Joint observations and investigations of solar chromospheric and coronal activity'
Rositsa Miteva, Werner Pötzi, Astrid Veronig +9
We present the bilateral collaboration between Bulgarian and Austrian solar and space weather researchers on the topic of chromospheric and coronal activity. This new project will…
Band Splitting in m-Type II radio Bursts and their Role in Coronal Parameter Diagnostics
Pooja Devi, Ramesh Chandra, Rositsa Miteva +2
Type II radio bursts are signatures of shock waves generated by solar eruptions, observed at radio wavelengths. While metric (m) type II bursts originate in the lower corona, their…
Type II radio bursts and space weather phenomena: A statistical study
Pooja Devi, Rositsa Miteva, Ramesh Chandra +2
In this paper, we present for the first time a comprehensive statistical study between type II radio bursts from the metric (m) to the dekameric-hectometric (DH) domain and their a…
