  "abstract": "Quasi-periodic Oscillations (QPOs) from magnetars bursts are rare, some high-confidence detections are mostly from magnetar Gaint Flares. Following a systematically research of bursts data from Fermi/GBM, here we report a 4.98$\\sigma$ ($p$-value is 6.51e-7) detection of high frequency QPO $\\sim$ 80 Hz in SGR 150228213. This burst has initially attributed to 4U 0142+61 by Fermi/GBM, however, it shows a different spectral features with other magnetar bursts, including burts from 4U 0142+61. More interestingly, we find the location of SGR 150228213 almost coincides with the periodic Fast Radio Burst source FRB 180916. Finally, we discuss the possible physical origins of this burst.",
