We have observed the field covering the error circle of
GRB GRB100511A (Swift trigger 421695)
with the unfiltered CCD camera on the 30-cm telescope
at University of Miyazaki.
The observation was started 14:19:42 UT, about two and
a half hours after the Swift trigger time.
We have compared our data of 30 sec exposures
with the USNO-A2.0 catalog,
There is no new source at the reported position.
the upper limits are as follows:
--------------------------------------------------------------
Start(UT) End(UT) Num. of frames Limit (mag.)
--------------------------------------------------------------
14:19:42 14:20:12 1 14.9
14:19:42 15:02:15 26 16.0

FROM: Adria C. Updike at Clemson U
Adria C. Updike, Dieter H. Hartmann (Clemson University), G. Grant
Williams (MMTO), and Peter A. Milne (Steward Observatory) report:
We observed the field of Swift trigger 421695 (Sbarufatti et al., GCN
10737) with the 0.6m Super-LOTIS telescope located at KPNO beginning 21
seconds after the trigger. Within the BAT error circle, we detect no new
sources to a limiting magnitude of R = 17.5 (as compared to the USNO B1.0
catalog) in our first 3 minutes of stacked exposures.

DATE: 10/05/12 16:51:05 GMT
FROM: Narayana Bhat at U Alabama/Huntsville/GBM
P. N. Bhat (UAH)
report on behalf of the Fermi GBM Team:
"At 00:49:56.23 UT on 11 May 2010, the Fermi Gamma-Ray Burst Monitor
triggered and located GRB 100511A (trigger 295231798 / 100511035).
The Fermi Observatory executed a maneuver following this trigger and
tracked the burst location for the next 5 hours, subject to
Earth-angle constraints.
The on-ground calculated location, using the GBM trigger
data, is RA = 109.29, DEC = -4.65 (J2000 degrees,
equivalent to 07 h 17.2 m, -4 d 39 '), with an uncertainty
of 1.0 degree (radius, 1-sigma containment,
statistical only; there is additionally a systematic
error which is currently estimated to be 2 to 3 degrees).
The angle from the Fermi LAT boresight is 43 degrees.
The GBM light curve shows several pulses
with a duration (T90) of about 38 s (50-300 keV).
The time-averaged spectrum from T0-7.4 s to T0+52 s is
adequately fit by a power law function with an exponential
high energy cutoff. The power law index is -1.32 +/- 0.02 and
the cutoff energy, parameterized as Epeak, is
946.6 (+134/-110) keV
(C-stat 1777 for 863 d.o.f.).
The event fluence (8-1000 keV) in this time interval is
(7.08 +/- 0.05)E-06 erg/cm^2. The 1-sec peak photon flux
measured starting from T0+25 s in the 8-1000 keV band
is 8.81 +/- 0.18 ph/s/cm^2.
A Band function fits the spectrum equally well
(C-stat 1776 for 862 d.o.f.) with Epeak= 882.5 +166/-115 keV,
alpha = -1.3 +/- 0.02 and beta = -2.43 (+0.24/-1.71).
The spectral analysis results presented above are preliminary;
final results will be published in the GBM GRB Catalog."
