D. A. Kann, A. Nicuesa Guelbenzu, F. Ludwig and B. Stecklum (TLS
Tautenburg) report:
We observed the afterglow of the bright Swift GRB 100906A (Markwardt et
al., GCN 11227) with the 1.34m TLS Schmidt telescope as soon as dusk set
in. We obtained 3 x 300 sec images in Z, Ic, Rc, V and B each. The
afterglow is clearly detected in all images.
Assuming the star at RA = 01:54:46.82, Dec. = +55:37:55.3 to have
USNOB1.0 R2 = 15.70, we find the following magnitude for the afterglow:
Rc = 18.84 +/- 0.03 at 0.247478 days after the GRB.
Further observations are planned if weather permits.
