Scientific paper

Previously, we have found that the counterpart to SGR 1900+14 underwent extraordinary spectral changes during burst active episodes in 1998 and 2001. It is during these epochs where we have gained the most insight into the nature of this source. SGR 1900+14 recently entered a new phase of activity starting on 2/17. Our ToO observation of the SGR on 2/19 with the RXTE PCA found the flux (2-10 keV) to be a factor of ~20 higher than expected. The pulsed signal of the SGR is not seen in the data, nor is the pulsed signal of a nearby Be transient (XTE J1906+09). There are no other catalogued X-ray transients in the 1 degree radius FWZM fov of the PCA. The power spectrum did show an excess level of red noise, similar to that seen in many BHCs. We conclude that we are observing either (i) the rise of a new transient or (ii) new behavior from SGR 1900+14 in an active state. A PCA raster scan has shown that the excess emission is consistent with the direction of the SGR.
