Target-of-opportunity observations of 2008am were obtained with the Swift XRT satellite (+ UVOT) on Feb. 6, 7, and 13 UT. No x-ray emission is detected at the position of the supernova. The 1100-s cleaned observation on Jan. 6 yields a 3-sigma upper limit of 2 x 10**(13) erg/cm2/s in the energy range 0.3-10 keV, assuming a power-law spectrum with photon index of 2. SN 2008am was detected by UVOT in all filters on Feb. 6, and the magnitudes through the various filters, all for the general period Feb. 6.69-6.83, are as follows: v = 18.8 ± 0.2; b = 19.2 ± 0.2; u = 18.2 ± 0.2; [uvw1] = 18.6 ± 0.2; [uvm2] = 18.5 ± 0.2; [uvw2] = 18.9 ± 0.3. Note that the aperture used to get the UVOT photometry includes the center of the host, which introduced large uncertainty in the magnitudes.
