Fellow southern Californians, There will be an excellent flare from Iridium 31 on Thursday evening, January 8th, around 17:33:40 PST in the L.A. area. The centerline track makes landfall near the Long Beach Naval Shipyard (a little west of the Queen Mary), heading more or less due north. (The track moves about 1 mile west for every 20 miles it moves north). Downtown L.A. and Glendale are probably pretty close to being on the track, and anywhere between the Harbor and Long Beach freeways. The sun will be about 6.5 degrees below the horizon, so it won't be completely "dark". But the peak magnitude should exceed -8 on the centerline: plenty bright to see in evening twilight. Clear skies! Rob
