You can disregard annual differences, since they amount only to +- 0.5 degrees, and most flares are good for a degree or more. Above all, pointing is not precisely what we assume for this model - some flare earlier, later or not at all, and some with non-zero inclination flare in the predicted area, or slightly outside. I have a spreadsheet calculating the outline of the shadow, the optimum solar reflection point, and the Clarke belt, for any date, time, location. The data can be pasted into Skymap's DEEPSKY.TXT for plotting along with predictions (or in Excel itself, or other graphing programs). /Björn ----- Original Message ----- Any reason why Jeff's plot from 2006 would not work this year? A slight difference due to the different day of equinox? Since optimum flaring season at +36 N is around last quarter moon, I am very interested in seeing the flares this season. ------------------------------------------------------------------------- Subscribe/Unsubscribe info, Frequently Asked Questions, SeeSat-L archive: http://www.satobs.org/seesat/seesatindex.html
