Filippenko (UC Berkeley) report on\n\nbehalf of the KAIT GRB team:\n\n\n\nThe 0.76-m Katzman Automatic Imaging Telescope (KAIT), located at\n\nLick Observatory, responded to GRB 230812B (The Fermi GBM team,\n\nGCN 34386) starting at Aug. 13, 04:42:53 UT. We detected an uncataloged\n\noptical afterglow candidate not shown in SDSS archive at position\n\nof (error ~0.5\"):\n\n\nRA:  16:36:31.52  (J2000)\n\nDec: +47:51:32.24 (J2000)\n\n\nThis position is about 7.4 arcsec to the improved Swift/XRT\n\nlocalization (Page et al., GCN 34393), which is slightly outside its\n\nestimate 3.7 arcseconds error radius.  We measure the target is\n\n~18.7 in out clear band image at ~9.75 hours after burst. We can\n\nnot estimate the variability at this time, further observations\n\nare encouraged.\n",
