A New Activity Cycle of V1413 Aql Open
V1413 Aql is an anomalous classical symbiotic star that has remained in an active state almost continuously. After failing to return to quiescence following the 2020 outburst, it underwent a new flare in 2025. We present an analysis of new…

On the Influence of ''Red Leak''of Light Filters on the Brightness Estimates of Stars of Late Spectral Types Illustrated by the Observations of Rapid Variability of Symbiotic Stars Open
The results of modeling the dependence of the red leak of photometric filters on various factors (color index V-R, luminosity class, interstellar reddening, airmass and PWV) during observations of stars are presented. The error arising fro…
