Yu (MPE) reports on behalf of the Fermi GBM Team:\n\n\"At 08:03:22.32 UT on 21 July 2014, the Fermi Gamma-Ray Burst Monitor\ntriggered and located GRB 140721A (trigger 427622605 / 140721336).\n\nThe on-ground calculated location, using the GBM trigger data, is \nRA = 175.7, Dec = -41.2 (J2000 degrees, equivalent to 11h 42m 48s, \n-41d 12'), with an uncertainty of 1.0 degrees (radius, 1-sigma\ncontainment, statistical only; there is additionally a systematic\nerror which is currently estimated to be 2 to 3 degrees).\n\nThe angle from the Fermi LAT boresight is 118 degrees.\n\nThe GBM light curve shows a multi-pulse feature with a duration\n(T90) of about 128 s (50-300 keV). The time-averaged spectrum from \nT0-6.400 s to T0+84.737 s is well fit by a Band function with \nEpeak = 129.0 +/- 10.2 keV, alpha = -1.05 +/- 0.05, \nand beta = -1.98 +/- 0.03.\n\nThe event fluence (10-1000 keV) in this time interval is\n(4.95 +/- 0.08)E-05 erg/cm^2. The 1-sec peak photon flux measured\nstarting from T0+18.752 s in the 10-1000 keV band\nis 14.0 +/- 0.5 ph/s/cm^2.\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog.\"",
