Discovery of mHz QPOs from the LMXB 4U 1323-619

We report on recent RXTE observations of the bursting, high-inclination low mass X-ray binary (LMXB) 4U 1323-619. The source was observed during two successive RXTE orbits for approximately 5 ksec beginning at 10:14:01 UTC on March 28, 2011. Significant mHz quasi-periodic oscillations (QPO) at a frequency of 8.1 mHz are detected for approximately 1600 s from the beginning of the observation until the occurrence of a thermonuclear X-ray burst at 10:42:22 UTC.
