Yesterday I saw what must have been two stars in broad daylight, or else I saw two geostationary satellites flaring brightly. I'm betting on the former, but it...

After working at it for almost four hours, members of my Observational Astronomy class look to have gotten an image of Stardust with our 0.4m telescope,...

This morning's sighting of a flare from Iridium 46 marked a milestone for me - I've now seen flares from all the operational Iridium satellites (defined...

On the evening of August 21 (2047 CDT, which would be 0147 UT on the 22nd), I noted three bright, slow, and irregular flares from an object moving northward...

I've had a gratifying response to my request for additional reports of telescopic tracking of the Apollo missions in' translunar coast.On a related topic,...

This came up a few weeks ago while I was travelling - so here goes. Just to confirm which ones show irregular flashes while tumbling, I leafed through my...

Consider this a "want ad" for observations of the Apollo lunar missions. I first started collecting pointers to this stuff while doing intro-astronomy lectures...

This morning the Shenzhou 6 booster appeared to change in brightness several times during its pass; also, it appeared a minute later than predicted on H-A. It...

I spotted Shenzhou 5 twice this morning. The first apparition came at 5:28 MDT, when it was at sixth magnitude and low on the horizon. The second apparition...

I just spotted the USA 181 booster, which appears to be tumbling at about 5 RPMs. It was easily visible in 10 x 50 binoculars, varying between magnitudes 5...

I caught DMSP-16 (the newly-launched USAF weather satellite) this evening (7:52 PM, MDT; from northern Utah). It was about sixth magnitude in binoculars, and...

I've spotted Shi Jian 6b (04035C) several times over the past few nights. It's flaring about five times per minute. I haven't managed to spot SJ 6A yet, so I...

This is from sci.space.news. The launch date is subject to change, but if the mission works it could give an interesting sight. MUBLCOM is 99-026. --Bill...

I just caught 04037C. The bird is flashing approximately fifteen times per minute. It's a Zenit-2/SL-08 upper stage, and H-A gives its orbital altitude as...

I just spotted Naxing-1 (04012C). It was flashing irregularly. Much of the time it was visible to the naked eye, up to magnitude 3 in brightness, but it faded...

Cosmos 1030 shed a piece of debris about a day before it re-entered last night. Apparently the object came off due to aerodynamic forces during one of the...

It appears to be tumbling slowly. I can't estimate the rate because the sky was moderately bright (less than an hour before dawn) and it faded from view...

Catching it took a six inch, f/8 Newtonian with a low-powered ocular, but it was right when and where Heavens-Above said it would be. The Delta second stage...
