Discovery of a 62-min long-period transient with near-orthogonal rotator geometry

We report the serendipitous discovery of J155543.7$-$563102 (hereafter LPT J1555$-$5631) with a period of 62.2 min in MeerKAT and ASKAP survey data. The source emitted bright (10-30 mJy), steep-spectrum ($\alpha\sim-1.5$), highly polarized radio pulses during a 15-hr active window in May 2022, with no other quiescent o...
