    Ir 27 t, observed for 150 secs. Started with bright -02.0 flashes that 
    brightened to a -3.0 or -4.0 at 01:42:46.4; then dimmed to minor flashes 
    around mag 0.0 at 01:43:06.83.  The flash's became Max's from 01:43:13.9
    to 01:43:34.96 secs; then a series of 2.0 Max's followed by a -1.0 flash 
    at 1 to secs after the max (notated below as M.f), this pattern continued to 
    01:44:49 where the Max-flash pattern began a pattern of double flashes around 
    mag -1.0 again seperated by about a second or two as were the Max-Flash pattern
    previous.  The most brilliant flashes of this double flash series are indicated with * 
    or ** with the ** being brighter than the *.  As Bjoern pointed out a near 
    seven second period is evident. (note that the stopwatch was used to 
    01:43:34.96 then a tape recording against NIST signals followed, hence
    a larger time error of a second will be evident in the data after 01:43:34.96).
