[1] In December 1997, PKS 2255-282 showed a gamma ray flare which lasted for a period of 2 weeks.

A 5 GHz radio image of the object made via Very Long Baseline Array, shows a strong bright core component marginally resolved at 2.8 Jy and a short jet extending southwest by 5 mas.

[12][1][13] However, when shown at higher frequencies, the jet is completely omitted from radio imaging with the core only present at 4.2 and 2.7 Jy.

[1] This core is estimated to have a size of 0.2 mas with extended emission in both south and east directions.

[14] A quasi-periodic oscillation was detected in PKS 2255–282 in October 2024 with a period of 97 days.
