The FIA Radar, USA 179 (SDS 3-3) and more

On the 5th, 9th, 10th and on the 16th of January, the skies shortly cleared in the evening and I observed the FIA 1 Radar (10-046A) making some nice passes through the winter sky. On the 16th it was a particularly close race with clouds coming in (the last image in the series has clouds in the image frame).

Below are two images: one from the 10th showing the FIA 1 Radar passing close to the Pleiades; the other showing it passing through the alpha Persei association on Jan 16th.

I also observed the Molniya orbit satellite USA 179 (SDS 3-3) on the 16th, which was close to the alpha Persei association too. As it was too faint for the 50mm lens, I used the Carl Zeiss Jena 180mm lens for it (brightest star in image is alpha Persei):

Other objects observed include PAN (09-047A) on the 9th of January. It is still in the fixed position at 49.0 E where it is since December 24 (see earlier post here). That same evening, Mentor 4 (USA 202), Mentor 2 and the Milstar 5 r/b were observed as well. A flashing H2A rocket, 06-059A, was captured as a stray. On the 5th of January, the IGS R2 r/b was captured in twilight, being very fast and very bright.

Observing again

Last night was very clear, and I finally could get myself to observe again after a 2-month period of inactivity (see previous post).

In 3 hours observing time I catched a nice batch of objects: USA 193 (06-057A), IGS 4A/R2 (07-005A), Lacrosse 3 (97-064A), Lacrosse 4 (00-047A), the Lacrosse 5 rk (05-016B) and a nice -2 flare of Iridium 14 (99-032A). I also visually observed IGS 1B (03-009B) but the trail ends on the image were to marginal to measure.

Below pictures showing:

- the Japase radar reco satellite IGS 4A/R2 and the American radar reco satellitre Lacrosse 3 in one and the same image, in Cassiopeia;
- the flare of Iridium 14.

Note: the times listed in the Iridium flare picture are 10 seconds off from the real time

First observation of one of the new IGS objects

I managed to observe one of the new Japanese IGS eastern plane objects for the first time this night (see image below). It concerned the rocket-booster, 07-005C (#30588), which amateur trackers name either IGS 4r or IGS R2r.

It made a zenith pass and was bright and easy, mag. +1.5 in the zenith and about +2 when passing close to Polaris. It was steady, no sign of tumbling.
