Mark, > Looks like here in So Cal we're headed for sets of 3 Iridium flares, > 10-20 deg high in the SW to W, each flare about 8.8 minutes after the > last one. It may be hard to see the fainter ones in murk. Here in Athens I have the pleasure of the triple flares for six consecutive days starting on June 17 and ending on June 22. Nice oportunity to fill in the "gaps" for any Iridium-specific flares not observed or imaged. > In some of the series, the Iridiums even flare in numeric order!

Same observation here as I have Iridiums 31, 32, 33 on June 17; Iridiums 57, 58, 59 on June 18; Iridiums 30, 31 and 32 on June 20. This six-day period of triple flares is then followed by lots of double-flare opportunities. Being new to Iridium flares, I wonder if certain parts of the year are better than others for frequency of flaring and/or lower/higher flare magnitudes. As far as the frequency goes, I would think not (?) since flares are most often observed following sunset and before sunrise. However, it is interesting to see how the flare azimuth during the course of the year keeps moving in a steady direction and pace. I would be interested to hear from the local experts if the flare magnitudes are generally correlated with the time of year?! > Mark Anthony. ----------------------------------------------------------------- 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
