We obtained a Swift observation of the field containing IGR
J00291+5934 on 2008-08-15 starting at 14:50 UT for approximately 2000
seconds of exposure.
We clearly detect IGR J00291+5934 with the XRT instrument,
confirming the previous report of outburst (Chakrabarty et al., ATEL
#1660). The source is rather piled up, but we can say that flux is
comparable to, or slightly smaller than, the flux reported by RXTE PCA.
A nearby intermediate polar source, V709 Cas, is also present in
the XRT field of view. The 0.5-10 keV flux of this source is
approximately 3.7 x 10-11 erg s-1
cm-2, based on a power law model with photon index 0.92.
Thus, V709 Cas contributes a significant amount of contamination to the
1 degree-radius field of view of the RXTE PCA instrument (but this may
depend on time).
