A bounty of GEO satellites on June 21

The night of June 21-22 was clear, and as I had trouble sleeping, I decided to take the short bicycle trip to my secondary site, Cospar 4355. This site is located in the polder only just outside of town, but the sky is better there than at my regular site 4353, which is in the town center (the secondary site is about 2 km south of my regular site). As a result, I can use twice as long exposures, which means I can image fainter GEO satellites than from my regular site. The site, being in a polder, also has less horizon obstruction. Below is a panorama of the site, split up in two parts, each slightly larger than 180 degrees. Azimuth directions are indicated.

I took some 54 picture (20 second exposures with a Canon EOS 60D + SamYang 1.4/85mm at 800 ISO) over the course of an hour. My main focus was on approximately 20-30 degree (1-2 camera fields) wide equatorial areas near azimuth 120-130 deg, 160 deg and 200 deg.

I captured a nice batch of objects: 17 classified objects, two Unknowns (initially four but two got ID-ed as classifieds) and A LOT of unclassified objects. The image in the top of this post shows an only 2.7 degree wide stretch of one image, and look how many objects are already in it.
One of the objects in the image, the defunct Russian military comsat Raduga 1-M1/Kosmos 2434 (2007-058A) was flaring repeatedly in subsequent images (compare also the two images in the top of this post).

The images below show two other swaths of sky only a few degrees wide. Various commercial GEO sats are visible, as well as two old Ariane r/b, of which several were captured this night:

It also shows  the British military communications satellite Skynet 5B (2007-0056B).

One of the classified objects captured this night was AEHF 2 (USA 235, 2012-019A), part the new military communications satellite constellation that is gradually replacing the Milsat system. Another object imaged was the SBIRS GEO 2 (2013-011A) satellite, part of the new infra-red Early Warning constellation that is replacing the DSP constellation.

The lower of the two images above (it is slightly blurry because it is the edge of the image) also shows one of the initial UNID's of that night, "UNID 2", one that Cees and Ted later identified as the classified Italian military communications satellite Sicral 1 (2001-005A), which has recently been moved to 22 E.

Cees also managed to identify another UNID I imaged that night, "UNID 3":

It is the object we amateur trackers designate as Unknown 130929 (2013-772A), an object in a Molniya orbit which was last seen 132 days before my observations (i.e. we temporarily "lost" it). It was over West Africa at an altitude of 1270 km at the time of observation, moving away from perigee:

Two other UNID's of this night remain to be identified. One of these ("UNID 1") appears to be in GTO: the other one ("UNID 4") appears to be in LEO and was very faint.

The image below shows two classified objects (plus several commercial geosats), both US Military communications satellites: USA 236 (2012-033A) and WGS 3 (2009-068A). WGS 3 is the third satellite in the Wideband Global Satcom constellation. USA 236 is a geostationary SDS data relay satellite. It is believed that they notably relay imagery of IMINT satellites in LEO, for example optical imageryby  KH-11 Keyhole/CRYSTAL and radar imagery by Lacrosse and FIA.

Mentor 4 and Thuraya 2 change of configuration

A change is occurring in the configuration of Mentor 4 (USA 202, 2009-001A), a huge Mentor /ORION SIGINT satellite, and the commercial communications satellite Thuraya 2. For over 3 years, Mentor 4 was stationed (as seen from my observing location) slightly south of Thuraya 2. On my June 21 imagery, it has moved to slightly North of Thuraya 2. Compare the top image from last June 21 with some images shot in previous years:

(The first image also shows the still unidentified UNID 1, likely in GTO, and  a classified r/b from another Mentor/ORION launch, Mentor 3 r/b (2003-041B)).
