We report on Gemini Observatory infrared and VLA radio observations of the Anomalous X-ray Pulsar 1E 2259+586 made just after its June 2002 X-ray outburst. In particular, we report a 2.15 micron brightening, relative to a quiescent measurement made in 2000, by factors of 1.33 +/- 0.22 mag and 0.56 +/- 0.29 mag, 3 and 10 days post-outburst, respectively. No evidence for radio emission was seen 2 days post-outburst, with 99% confidence upper limit of 0.050 mJy at 1.4 GHz. We discuss these results in the context of the magnetar model.

This research was supported in part by NSERC, CIAR, and NASA.
