This an image I'd been trying to make for several weeks, but something always managed to intrude on the idea - life, family, work, weather, always something! And the day before I finally managed this, the prediction for an even brighter flare (16x brighter than this, or even more!) off the Iridium 82 satellite failed to materialise (Iridium 82 turned up at the right time, but must have spun out of control or recently failed, because it was very dim and remained so - there was no flare).

The night that I took this, it was almost completely overcast when I left the house. But I was determined to at least try. I set up 45 minutes early and acted all stubborn. And it worked! 10 minutes before the satellite pass, it started clearing, and fast! The above is the result of my stubbornness (I mean determination :D).


Iridium 18, flaring up to magnitude -4.2 over Kiama harbour, on the night of April 8, 2013:

Then this morning, in-between wind gusts that were predicted to be up to 90 km/h (the tripod, camera *and* camera bag hanging under the tripod were picked up completely off the ground a couple of times, lucky I was hanging onto the tripod at all times!), I took this image:

Iridium 13, flaring up to magnitude -6.1, over Surf Beach, Kiama:

Unfortunately resizing and Web compression kills a lot of the original detail, but I still hope you like 'em. :) Comments welcome!

Congrats on your nice shots, glad you were persistent in your endeavor. I grabbed this shot of Iridium 25 last evening while watching for any late Perseid meteors. It was quite by chance, and I had no idea it would flare. I saw it crossing the sky, so I triggered a 30 second exposure and got lucky. I checked the Heavens Above site and saw it listed as Iridium 25.

Nice indeed.

Thanks!

Caught another one earlier tonight. The Sun was not set all that long, and the Moon was lighting up the rest of the sky, so not too many stars in this one.

Iridium 98 flaring up to magnitude -4.1:

Excellent shots Rudi! I like the first one best - the framing of the trees and the symmetric "taper" at both ends of the flare appeal to me. Well done!

Alright folks, another couple from me (let's keep this thread going!).

Iridium 65 satellite, flaring up to magnitude -8.1 (about as bright as they get). The bottom of the flare is pointing almost directly at the Pleiades (The Seven Sisters), and Orion and his sword (seen upside-down in the Southern Hemisphere) can be seen in the top right hand corner of the image, about a third of the way in from left:

IMAGE: http://rudiphoto.net/img/s1/v19/p2141580051.jpg


And one from earlier tonight - Iridium 32 satellite, flaring to magnitude -6.4 over Bombo Beach. Kiama Lighthouse is the bright white light near the left of the frame. The Large Magellanic Cloud, a galaxy orbiting our own Milky Way, is the bright "cloud" directly to the left of the Iridium flare:
