It appears that I have been able to match Jim's observations to my old flash model for ETS-6. Most observers should have opportunities for 1-power flashes from Eridanus to Lepus; if the back sides are also reflective they may also appear in Canis Major. There is scarce old evidence for a third surface that I have called 'C' - it may have reflections in Cetus. If the model is correct, there are also flashes over large "circles" across the sphere. To find predictions for a few days around 01-11-17, download deepsky.txt from my home pages http://www.algonet.se/~b_gimle/ETS-6.htm (copy your old SkyMap version first, if you have one, or download into another directory). You can replace your original SkyMap file, or just the first line, by this file, or just use its RA(h.h) / Dec (d.d) / "mag" values to plot manually. Mag. 0.6 means observed flashes, 3.6 hypothetical back side. Set your deepsky (F8) to On, and mag. limit accordingly. > > 14-Nov-2001 > First flash noticed "about" 10:08:30 UTC. > 16th +2nd mag. flash seen "about" 10:10:45 UTC. > The 135 second time range is accurate. > All timings yielded 9.0 second intervals based on observations recorded > to the nearest second. > Four flashes of less than 2nd mag. followed; > Then two of less than 3rd mag. ----------------------------------------------------------------- Unsubscribe from SeeSat-L by sending a message with 'unsubscribe' in the SUBJECT to SeeSat-L-request@lists.satellite.eu.org http://www.satellite.eu.org/seesat/seesatindex.html
