New activity cycle of the classical symbiotic star V1413 Aql

We present the results of our photometric UBV JHKLM observations in 2008-2011 for the classical symbiotic star V1413 Aql. At the end of 2008, the hot component of V1413 Aql experienced the next strong outburst (Δ V > 2{_·/ ^m }5). According to the photometric criterion ( B-V ≈ 0{_·/ ^m }9 ± 0{_·/ ^m }2), the star was in an active state even in the period preceding the strong 2008 outburst. Two eclipsing minima of the same amplitude were observed for V1413 Aql in 2010 and 2011. Our analysis of the 2011 eclipse has allowed us to estimate the sizes of the components with respect to the orbital semimajor axis if the system is seen edge-on: the radius of the cool component is R _g/ a = 0.28 and the radius of the hot component is R _h/ a = 0.17. However, judging by the B-V color index, the eclipse may be noncentral.
