Description
The transient black hole candidate GX 339-4 is currently softening in X-ray, making a transition out of the hard state (ATel #2545). We are monitoring the source with the Faulkes Telescope South (located at Siding Spring, Australia) and the SMARTS 1.3m telescope and ANDICAM instrument (at Cerro Tololo, Chile). From the Faulkes monitoring, the source brightened in the hard state over the last five months from a faint (V = 19.6, R = 18.8, i' = 18.6; errors are 0.1 mag at most) magnitude on 2009-10-22 = MJD 55126 (ATel #2270) to a bright (V = 15.1, R = 14.5, i' = 14.3, V-i' = 0.79) one on 2010-04-01 = MJD 55287 (with a very bright radio jet; ATel #2525).

    Measuring Rotation Periods and Stellar Oscillations in Red Giants with TESS Data
    TESS is a powerful engine for studying stellar variability. However, it has been challenging to adopt methods used for other space missions, such as Kepler, to infer rotation periods and solar-like oscillation frequencies in TESS data. The availability of multiple sectors of data for most targets, improved stability, and the release of new
