Abstract
We have made IRAS (12, 25, and 60 mu m) maximum entropy images of the three known soft gamma repeaters SGR 0526-66, SGR 1806-20, and SGR 190 0+14. In addition we have obtained a high-resolution 10 mu m image of SGR 1900+14 using TIMMI at the ESO 3.6 m telescope. All three SGRs hav e associated with them an infrared source. The infrared emission assoc iated with SGR 0526-66 likely originates from heated dust in the super nova remnant N49. The infrared properties of the two galactic SGRs ate similar; both are unresolved at 12 and 25 mu m, and extended at 60 mu m. The relation of these infrared sources (if any) to the SGRs is as yet unclear.
