New VMO server 11 Sep 2009Today Geert Barentsen is here - we get new hardware for our server of the Virtual Meteor Observatory (VMO) and he is helping to transfer the database. Our new server is a Dell Poweredge 2600 with 6 harddisks in a configuration such that if one breaks down, it can be swapped without the user noticing. Again we acknowledge the support of our computer team working with Gunther Thorner in supporting us, in particular Yogi Stuwe who installed the new machine for us. |
Perseids 2009 |
13 Aug 2009The night 12/13 Aug was reasonably clear, with about 50 % clouds 'only'. Our intensified LIC1 saw almost 400 meteors! And also with the SPOSH camera we recorded >160 meteors. Now we just have to see how many parallel meteors we have with the other SPOSH camera operated by DLR north of the Alps. |
11 Aug 2009The f irst two nights we had clouds and rain. On the evening of 11 August, there were a few hours of clear skies. Now (12 Aug, 00h15m) it gets cloudy again. Anyway, we have recorded some meteors! Here the first Perseid recorded with LIC1,

09 Aug 2009We have arrived at the Kanzelhohe Observatory! We, that is Andre Knoefel (International Meteor Organisation) and myself yesterday, Hakan Svedhem today. Unfortunately the weather is bad, it's raining. And Detlef's remote camera in the Netherlands shows clear skies... We are on an observing campaign with DLR Berlin, using our SPOSH cameras. Here the field of view of our cameras at Kanzelhohe and Gahberg (both Austria) when pointing zenith (left) and when pointing our camera only 10 deg above the horizon (right). Let's hope we can use them.

New (wo)manpower01 Jul 2009We welcome a new team member - Maria Gritsevich from Moscow started working in our Meteor Research Group on 01 July. She will focus on modelling the light emitted from meteors in the infrared - this is to help us modelling what an Infrared meteor camera could see from space. |
 The roofs have arrived30 May 2009The automated roofs for our double-station setup have arrived. They were ordered from the company ' Pier-Tech ' in the US. Currently we are getting acquainted with its operation in the lab. Christian Erd will go to the Canaries in August to finalize the locations for setting them up. |
CILBO becomes SILBO17 Mar 2009 The Canary Islands Long Baseline Observatory (CILBO) has had a change of name. Its objectives stay the same but it is now called the Spanish Islands Long Baseline Observatory (SILBO). Initially we thought it was clever and witty to call a system based on the Canary Islands CILBO due to the fact that this would be pronounced by locals on the Island in the same that "mainlanders" pronounce SILBO - meaning a whistle. The acronym "SILBO" has a historical relevance to inter-mountain, if not inter-island, collaborations. The Silbo Gomero ("El Silbo" or "Gomeran whistle") is a whistled language spoken by inhabitants of La Gomera in the Canary Islands to communicate from mountain to mountain across the deep valleys (barrancos) that radiate through the island. |
 VMO - again...07 Mar 2009We continue working on the Virtual Meteor Observatory. In the last week of January, both Andre Knofel and Geert Barentsen were visiting ESTEC and we worked on a new fireball ball form for the VMO as well as other things.
And - a paper summarizing the ISSI team meeting 'A Virtual Observatory for Meteoroids' (see the article from 02 Dec 2008) was published in WGN, the journal of the IMO. |
More progress on the Virtual Meteor Observatory02 Dec 2008During the week 24-28 Nov 2008, we had an ISSI workshop on 'A Virtual Observatory for Meteoroids', organised by Rainer Arlt of the International Meteor Organisation together with Geert Barentsen. Several meteor observer groups presented their setups - the University of Western Ontario in Canada, the Polish Fireball Network, the IAU Meteor Data Center, the European Network from DLR Berlin, the Ondrejov Observatory in the Czech Republic, and more. We discussed the data one should store in a virtual observatory and other issues. Geert presented the current VMO, and everybody gave comments on the data model and the structure of the VMO.

The SPOSH-IR - an infrared version of the SPOSH camera Nov 2008 We have kicked-off a contract with JenaOptronic to develop a breadboard for an infrared version of the SPOSH camera. It will demonstrate that we can build a flight sensor observing the night side of a planet in the infrared (0.9 to 2.5 microns). The breadboard will be built based on the SPOSH design, using a focal plane from Sofradir. |
ATV reentry observations29 Aug 2008ESA/RSSD's Meteor Research Group participated in observing the reentry of the Automated Transfer Vehicle (ATV). The night-time reentry was observed with many instruments - video cameras, still cameras, and spectrometers - from two airplanes, a DC-8 and a Grumman Gulfstream V. Jason Hatton operated a SPOSH camera on loan from DLR Berlin, Jonathan Mc Auliffe operated our ESA SPOSH camera. We also gave a Watec 120N camera to Jason. The Watec did not work, probably due to a cabling issue. Both SPOSH cameras delivered good images of the ATV reentry. The DLR SPOSH on the Gulfstream recorded about 220 images in the time from 13h43m52s UTC to 13h47m00s UTC (about 1-2 Hz frame rate). The ESA SPOSH recorded ca. 250 images from 13h44m21s to 13h48m16s. The exposure times were 0.2 s for the DLR SPOSH, 0.4 s for the ESA SPOSH, resulting in limiting stellar magnitudes of 5-6 mag. We are currently analyzing the data - the main goal is to produce astrometric measurements which can be used to determine the precise (<100 m accuracy) position of the photometric center of the object.  The DC8 from which Jonathan used the ESA SPOSH. For more information on the campaign, see the ATV reentry page here. |
Perseids 2008 updates26 August 2008 The Perseids showed an unexpected outburst in the morning of August 13. The first results, based on visual observations gathered by the International Meteor Organization (IMO) and analyzed by a member of the ESA/RSSD Meteor Research Group at ESTEC, show a peak at August 13 01h53m +/- 15m UT with a rate of ZHR = 75 +/- 10.mThese initial findings have been published in IAU Telegram CBET 1480 . 12 August 2008Perseids observations are severely disturbed by poor weather conditions in The Netherlands this year. Nevertheless, several enthusiast ESA employees went out and reported seeing a few meteors visually through the clouds in the night of 11 August. ESA's SPOSH camera (Smart Panoramic Optical Camera Head) was given to DLR Berlin on loan for the DLR-organized Perseid observing campaign around Berlin. Let's hope that they had better weather... |

MRG SPOSH Camera to Capture the Quadrantids13 December 2007 This week the MRG's SPOSH camera is being shipped to California to be used by Jason Hatton as part of the international Quadrantid MAC mission coordinated by SETI's Peter Jenniskens. This campaign will take a team of scientists from the sunny coast of California to the skies over the frozen Arctic. Read more... |
ESA Meteor Research Group Heads to Hawaii27 August 2007 This week members of the ESA/RSSD Meteor Research Group (MRG) travel to the Hawaiian Islands to observe a rare outburst of the Aurigid meteors at 11:37 UT on the 1stSeptember. This campaign is being carried out in collaboration with research groups from Kobe University and Kochi University of Technology, Japan. The teams observe from two sites: one at the Onizuka Visitors' Center on Hawaii and the other from the Haleakala Observatory site on Maui. Visual and spectroscopic observations will be made of the luminous meteor phenomena assoicated with the disintegration and ablation of dust particles in the Earth's atmosphere. In the case of the Aurigid meteor shower the ablating dust particles are believed to have been produced by Comet Keiss during its second to last perihelion passage around 82 B.C. In addition to the observations on Hawaii, the MRG's Jason Hatton will take part in an airborne Aurigid Campaign organised by Peter Jenniskens of the SETI Institute. Read more... |
Perseids 2007 peak captured by ESA/RSSD/MRG13 August 2007 From the evening of Sunday 12 August to the early hours of Monday 13 August scientists from the ESA/RSSD MRG were camped out at the Kanzelhöhe observatory in Austria attempting, in coordination with other ESA teams and groups from DLR Berlin, to capture this year's Perseid meteor shower peak.
"The sky has cleared now enough for us to get a reference stars image for our video cameras, so they are now pointing in the right direction (towards Joe Zender in Schladming) and are waiting for some "juicy" Perseids. The SPOSH camera is ticking away happily. And the Watec system that will fly with Jason Hatton on Peter Jenniskens' Aurigid MAC mission at the end of the month is also operating."
