Modeling brightness temperature of sunspots using ALMA single-dish observations
F. Matković, R. Brajša, A. O. Benz +5
We model sunspot brightness temperature in the wavelength range 0.3-10mm using the Atacama Large Millimeter/submillimeter Array (ALMA) single-dish measurements together with other…
Modeling brightness temperature of prominences on the solar disk using ALMA single-dish observations
F. Matković, R. Brajša, A. O. Benz +5
Prominences (PRs) are among the most common solar phenomena, yet their full physical picture, particularly their chromospheric mm emission, remains incomplete. The new Atacama Larg…
Calculated brightness temperatures of solar structures compared with ALMA and Metsähovi measurements
F. Matković, R. Brajša, M. Kuhar +6
The Atacama Large Millimeter/submillimeter Array (ALMA) allows for solar observations in the wavelength range of 0.310 mm, giving us a new view of the chromosphere. The measured…
Geomagnetic storm forecasting from solar coronal holes
Simona Nitti, Tatiana Podladchikova, Stefan J. Hofmeister +3
Coronal holes (CHs) are the source of high-speed streams (HSSs) in the solar wind, whose interaction with the slow solar wind creates corotating interaction regions (CIRs) in the h…
A prediction for the 25th solar cycle maximum amplitude
R. Brajša, G. Verbanac, M. Bandić +3
The minimum - maximum method, belonging to the precursor class of the solar activity forecasting methods, is based on a linear relationship between relative sunspot number in the m…
On the Determination of the Solar Rotation Elements i, Ω and Period using Sunspot Observations by Ruđer Bošković in 1777
Mirko Husak, Roman Brajša, Dragan Špoljarić
In September 1777, Ruđer Bošković observed sunspots for six days. Based on these measurements, he used his own methods to calculate the elements of the solar rotation, the longitud…
