The sub- and quasi-centurial cycles in solar and geomagnetic activity data series/v.3
Boris Komitov, Stefano Sello, Peter Duchlev +3
The subject of this paper is the existence and stability of solar cycles with durations in the range of 20-250 years. Five types of data series are used: 1) The Zurich series (1749…
Sunspot minimum between solar cycles No 23 and 24. Prediction of solar cycle No 24 magnitude on the base of "Waldmeier's rule"
B. Komitov, P. Duchlev, K. Stoychev +2
The main purpose of this study is the determination of solar minimum date of the new sunspot cycle No 24. It is provided by using of four types of mean daily data values for the pe…
Synthetic solar X-ray flares time series since AD 1968 /s2
B. Komitov, P. Duchlev, K. Koleva +1
On the base of the most qualitative GOES satellites data for the period AD 1980-2009 and multiple regression model the "synthetic" series of the monthly numbers of soft X-ray flare…
UBVRI observations of the flickering of RS Ophiuchi at Quiescence
R. K. Zamanov, S. Boeva, R. Bachev +9
We report observations of the flickering variability of the recurrent nova RS Oph at quiescence on the basis of simultaneous observations in 5 bands (UBVRI). RS Oph has flickering…
