Attempt at a double

More chance synchronicity produces an aircraft playing snooker with a likely  Cosmos satellite!

Like buses again

Having waited a considerable time for an Iridium flare to show they now seem to be arriving in abundance. This one was Iridium 59 which achieved magnitude -3.2. Like my last Iridium post it just managed to hit its bright spot just as it departed the frame. Unfortunately it coincided with the gap between exposures which, by necessity, is at least 2 seconds. This allows for the camera to fully process each exposure and if not included results in dropped frames.

Quartet

Another synchronous performance as these 4 objects contrive to fly over at the same time. The early evening is now noticeably the busiest period as the sun begins to set deeper and the majority of the lower orbiting satellites become eclipsed more readily than during the summer months.

Not so bright

Not all Iridium flares are spectacular. This is Iridium 91 which managed to achieve its brightest point just as it was departing from the frame. At a meager magnitude -1.2 it was much dimmer than my previous Iridium posted on 4/10/2013.

Like a snail

Not very spectacular and difficult to spot this faint object was traveling extremely slowly. It was visible on every one of a sequence of 116 frames (each a 40 second exposure). The first of which was taken at 21.37.59 the last taken at 23.00.20.  Its direction of travel was more than 45 degrees to the sidereal motion of the stars so not very geostationary.
The Andromeda Galaxy is prominent at the top of these images.

Crossed purposes

Sometimes they look intent on colliding with each other.

A brighter visitor

The law of averages made it likely that an Iridium flare would show up eventually on one of these random sessions. This one just managed to get in the frame....It is Iridium 95 and achieved magnitude -5.8 at the brightest point.
