Video: ATV 3 'Edouardo Amaldi', a meteor, and the ISS this morning




This morning I was up early to capture the 3:29 UTC (5:29 am CEST) pass of ESA's space freighter ATV-3 "Edouardo Amaldi". This was just before the start of twilight, so the sky was still dark and several stars can be seen on the video. The video was shot from the center of Leiden town, from the east-facing window of my girlfriend's  appartment. Camera: WATEC 902H + 1.4/12mm lens.

The ATV emerged from Earth shadow at about 38 degrees elevation in the E-SE. Initially mag. +1, it was easily visible by the naked eye, then faded as it descended towards the horizon.

The movie also features footage of a nice 3-second meteor that appeared only a few minutes before the ATV pass: as well as footage of the ISS passing the same sky area about 30 minutes before the ATV.

 Brightest star in the FOV is Altair (alpha Aquila), with the stars of the Arrow just upper left of the center, and stars of the Dolphin near the GPS clock.

Below is also a photographic image, a 6-second exposure with the Canon EOS 450D + EF 2.5/50 mm Macro lens, showing the ATV on the border of Aquila and Sagitta.

Footage of ATV 3 passing in morning twilight of March 24





The footage above shows the European cargoship ATV 3 'Edouardo Amaldi' as it passed over Leiden this morning near 4:54 UTC (5:54 am local time), deep in morning twilight (sun at less than -7 degrees elevation only). In the opening shot, Arcturus can be seen top right, and the ATV will appear from behind the chimney-pipe of the roof below.

ATV 3 was bright (magnitude 0 to -1.5) and easily visible by the naked eye. It was somewhat orangish in colour. Once past culmination, I lost it in the twilight glare to the east.

The footage was recorded with a WATEC 902H camera and a 1.4/12mm lens.

I also made some photographic pictures this morning, including this one:

ATV 3 was launched by ESA yesterday from Kourou in French Guyana, and is on its way to the International Space Station (ISS) with supplies. I observed it yesterday morning as well, only 22 minutes after launch (see post and pictures here).

Newly launched ATV 3 cargoship in twilight

This morning at 4:34 UTC, the European Space Agency ESA launched the third Automated Transfer Vehicle (ATV) cargoship, ATV 3 "Edouardo Amaldi", from Kourou in French Guyana, bringing supplies to the International Space Station.

Only 22 minutes later, around 4:56 UTC (5:56 am local time), it made a pass visible from Europe. The ATV was still connected to the Ariane upper stage at that moment. As seen from Leiden, it was a low pass at a maximum elevation of 24 degrees in the S-SE, and in deep twilight: sun at -7 degrees altitude.

Nevertheless it was easily visible by the naked eye around culmination, as a fast and steady mag. 0 to -1 object moving against a bright blue twilight background. The picture above is a 4-second exposure taken with the Canon EOS 450D + EF 2.8/24mm lens, 400 ISO.

Note added 24/03/2012: More observations from following nights, including video of a pass on the 24th, available here.
