Price of the Caltech-NRAO-CARA GRB\ncollaboration, report:\n\n\"We have made Digital Palomar Observatory Sky Survey (DPOSS) images of\nthe GRB 010921 error box (GCN #1097) publicly available through the\nReact Group webpages at:\n\n    http://www.srl.caltech.edu/~react/GRB010921.html\n\nThe images may also be accessed directly as:   \n\n    http://www.srl.caltech.edu/~react/fits/GRB010921j.fits\n    http://www.srl.caltech.edu/~react/fits/GRB010921f.fits\n    http://www.srl.caltech.edu/~react/fits/GRB010921n.fits\n\nThe images are 1801x1801 pixels, centered at (J2000) RA 22:55:34.86,\nDec +40:56:32.1, and covering 30'x30'.  The images are from the second\nPalomar Sky Survey and were digitized at STScI; they have subsequently\nbeen corrected for vignetting effects and have corrected astrometric\ncoefficients in the image headers.  Note that the image bandpasses are\ngreen (j), red (f), and near-infrared (n), corresponding,\nrespectively, to the IIIa-J, IIIa-F, and IV-N emulsions used in the\nsurvey.  Going forward, we hope to make DPOSS images of GRB fields in\nthe northern hemisphere available on a regular basis.\n\nPlease contact Ashish Mahabal <aam@astro.caltech.edu> or one of the\nother authors of the Circular if you have any questions.\"",
