Optical flickering of the symbiotic star CH Cyg
K. A. Stoyanov, J. Marti, R. Zamanov +6
Here we present quasi-simultaneous observations of the flickering of the symbiotic binary star CH Cyg in U, B and V bands. We calculate the flickering source parameters and discuss…
Intra-night variability of the blazar CTA 102 during its 2012 and 2016 giant outbursts
R. Bachev, V. Popov, A. Strigachev +6
We obtained and analyzed more than 100 hours of multicolour optical time series of the blazar CTA 102 during its 2012 and 2016 outbursts. The object reached almost 11-th mag at the…
Difference between the optical flickering colours of cataclysmic variables and symbiotic recurrent novae
R. Zamanov, S. Boeva, G. Latev +2
We performed simultaneous observations in 3 bands (UBV) of the flickering variability of the recurrent novae RS Oph and T CrB at quiescence. Using new and published data, we compar…
The high activity of 3C 454.3 in autumn 2007. Monitoring by the WEBT during the AGILE detection
C. M. Raiteri, M. Villata, W. P. Chen +5
The quasar-type blazar 3C 454.3 underwent a phase of high activity in summer and autumn 2007, which was intensively monitored in the radio-to-optical bands by the Whole Earth Blaza…
