Cees, The observation report formats were discussed recently - there are programs to help you maintain the log! See e.g. http://www2.satellite.eu.org/seesat/Aug-2000/0006.html http://www2.satellite.eu.org/seesat/Aug-2000/0107.html http://www2.satellite.eu.org/seesat/Aug-2000/0108.html If your obs' coordinates (14h52m24.3s 20°24'14" see CeesObs.jpg) represent the star, it is not Epoch 2000.0. See attached CeesStar.jpg (14:52:07.9, +20:17:39.6) from Rob Matson's Skymap (Hipparcos catalogue). If you gave the star coordinates, the obs error could be large. If you record " 1/3 the distance to the star one degree away in direction 140 degrees" your error is likely to be smaller than if you try to estimate the distance and direction from the star. You could of course compute the position by linear or trigonometric interpolation , using this and the positions of the two stars, but your mental image of "1/3" may be better than the actual numbers, so marking it with a pencil or the PC crosshairs gives you more accuracy (you are likely to make approximately the same estimation error). See C:\TLE\CeesSampleReadout.jpg as an example. -- b_gimle@algonet.se (home) http://www.algonet.se/~b_gimle -- -- COSPAR 5919, MALMA, 59.2576 N, 18.6172 E, 23 m -- -- COSPAR 5918, HAMMARBY, 59.2985 N, 18.1045 E, 44 m -- -- SeeSat-L / Visual Satellite Observer Home Page found at -- -- http://www2.satellite.eu.org/satintro.html -- ----------------------------------------------------------------- Unsubscribe from SeeSat-L by sending a message with 'unsubscribe' in the SUBJECT to SeeSat-L-request@lists.satellite.eu.org http://www2.satellite.eu.org/seesat/seesatindex.html
