Field of 1FGL J1018.6–5856 as seen by the Sydney University Molonglo Sky Survey (SUMSS) at 843 MHz. Contours start at two times the rms noise level of 2 mJy with increments of . The emission in the region is dominated by the SNR G284.3−1.8 (delimited by the east and west arcs) and its interaction with molecular clouds (e.g. the north-east strong filament). The filled red dot represents the current position of 1FGL J1018.6–5856, while the empty red dot represents the position of the source 10 kyr ago (when the supernova that created SNR G284.3−1.8 took place). The red arrow represents the proper motion of the binary system and the predicted position in 100 kyr. The orange star in the west denotes the position of the pulsar PSR J1016−5857 and its associated PWN.
