We report on a Swift observation of the nearby active galaxy Mrk 1310, starting on November 14, 2024. The X-ray telescope obtained 812.4 seconds of exposure. From the NASA/IPAC Extragalactic Database, the X-ray flux recorded using the ROSAT telescope is F = 1.4 +/- 0.1 E-11 erg/cm^2/s in the 0.1-2.4 keV band. In this telegram, we compare that value to the latest observation with the Swift/XRT.
A 0.3-10.0 keV spectrum was created using OBSID 03111740007, and fit within XSPEC minimizing a Cash statistic. An absorbed power-law model (tbpcf*pow) yielded a power-law index of approximately Gamma = 1.3 +/- 0.2, a normalization of K = 7 +/- 1 E-4, and no measurable absorption column. This translates to a flux of F = 6 +/-1 E-12 ergs/cm^2/s (0.3-10.0), or F = 1.9 +/- 0.3 E-12 erg/cm^2/s (0.1-2.4 keV). This is approximately an order of magnitude lower than the observations made with ROSAT in 1990, and signals dramatic variability in this source. Further observations are encouraged.
