Blazar 4C+29.45 (Ton 599 or 1156+295) is monitored by Swift in X-ray. Here we report the recent high flux activity observed during the first week of the year 2023.
Preliminary analysis was performed using the online tool (Evans et al. 2009) and 0.3-10.0 keV unabsorbed flux was estimated by using the power-law spectral model. On January 02, 05, and 08, the flux was estimated as (8.60+/-1.40)X10^-12, (6.50+/-1.20)X10^-12, and (9.20+/-1.20)X10^-12 erg/cm^2/s suggesting a high flux state with photon index 1.46+/-0.19, 1.50+/-0.15, 1.70+/-0.14. The reported fluxes are 2-3 times higher than the flux observed on 17 January 2022 which was 3.5+/-1.3)X10^-12 erg/cm^2/s.
The increase in the X-ray flux also coincides with the high energy gamma-ray activity reported in Atel#15853 suggesting simultaneous flaring activity in the source. A quick look at the Fermi-LAT light curve also suggests a long-term activity going on in the source (https://fermi.gsfc.nasa.gov/ssc/data/access/lat/LightCurveRepository/source.html?source_name=4FGL_J1159.5+2914#).
Our proposed ToO monitoring will continue to monitor this source. We encourage further multi-wavelength monitoring of this object. We would also like to thank the Swift Team for scheduling of the ToO observations.
