Patrick Wils:
I was a bit too fast when I identified some "stars" with the minor planet (387) Aquitania before. These are the correct ID's from collected.big: 26879, 26866, 26854, 26834 and 26824. The other objects I mentioned appear to be genuine stars, but located within a "void" in GSC 1.2. The photometry of Aquitania shows a nice brightening of about 0.4 mag to a maximum and the start of the fading: #JD-2452000 V I 278.7102 12.436 11.539 278.7119 12.580 11.592 278.7137 12.560 11.548 278.7207 12.535 11.552 278.7225 12.495 11.577 278.7243 12.471 11.538 278.7261 12.531 11.506 278.7296 12.519 11.505 278.7313 12.353 11.539 278.7331 12.392 11.496 278.7366 12.442 11.476 278.7402 12.357 11.457 278.7437 12.407 11.415 278.7490 12.266 11.427 278.7508 12.274 11.411 278.7578 12.271 11.347 278.7596 12.333 11.357 278.7613 12.200 11.342 278.7631 12.252 11.291 278.7684 12.143 11.259 278.7772 12.179 11.266 278.7843 12.145 11.252 278.7860 12.117 11.272 278.7913 12.183 11.280 278.7966 12.262 11.346 I don't know whether the rotation period is known, but with a little more data, it could have been derived.
