JUN2011 Continuing with tower and dish maintenance (when it's not snowing!).
MAY2011 Katrina Bossert, a graduate student from the University of Colorado, Boulder, is on-site for almost a month running the lidar systems. She's shown here enjoying the first class seats on the way north.
APR2011 Additional channels added to the RADAC system allowing for a lot more flexibility, including simultaneous measurements of both the up- and down-shifted plasma lines, raw data sampling, the addition of light-ion measurements concurrent with standard operating modes, etc.
MAR2011 Up-converter installed, ready to let the transmitter be controlled by the RADAC (RAdar Data ACquisition) system, and also allowing for sampling of the transmitted pulses.
FEB2011 Doing plasma line runs, coordinated with EISCAT Svalbard Radar, for Asti Bhatt of Millstone Hill.
JAN2011 Surveillance radars are fully refurbished.
DEC2010 Robert Michell and Marilia Samara, both from Southwest Research Institute, have installed a narrow-field imager for the season. Lots of radar operations with the new tube.
NOV2010 The new CPI klystron arrives and is installed. Data acquisition begins with baking and tuning on 13  November.
Katey Anthony and assistant visit from the University of Alaska, Fairbanks, and collect data for their study on methane trapped in lake ice.
OCT2010 Making preparations for receiving and installing the new klystron.
SEP2010 Adam Tishman, a recent employee of the Space Physics Research Lab at Embry-Riddle Aeronautical University in Daytona Beach, FL, agreed to spend three weeks scraping paint at the site. Adam seemed to enjoy his "paid vacation," topped with a trip to the ice cap.
We have a new vehicle! The used Land Cruiser from Nuuk was just delivered from the ship.
AUG2010 Subreflector brought down to the high-bay and patched and resurfaced.
JUL2010 Christian departs, back to Denmark. Best wishes to him and many thanks for his contributions over four years at the site.
JUN2010 Susanne Toball, a graduate student at the Karlsruhe Institute of Technology in Germany, visits for a week collecting particle samples for her dissertation.
MAY2010 CPI tells us they have had a failure in the assembly process of the new tube. It will not be ready for delivery in June, as planned, but we are hopeful it will be ready in August.
APR2010 The old Lytton klystron has failed. The performance of this tube had been slowly degrading since it was re-installed in late August. Each time the system was brought up, it requqired two operators for many hours before it stabilized enough to allow the normal one-person operation. As a result, we have been scheduling the experiment to be contiguous, as much as possible. Unfortunately, this tube cannot be rebuilt again. We are off the air until the new klystron is delivered, hopefully in June. Major maintenance tasks are being scheduled to take advantage of this downtime.
Site crew provides assistance to the University of Colorado, Boulder, and NOAA campaign for validating their new lidar system, CAPABL (Cloud and Aerosol, Polarization and Backscatter Lidar), before it's deployed to Summit Camp.
MAR2010 The new Color All-Sky Imager (CASI) is installed and tested. Data have been archived and acces is at with keograms, summary movies, and much more.
FEB2010 Anja and Ryan Neely (a graduate student at the University of Colorado, Boulder) join Eggert in hosting a field experiment with students from Qinnguata atuarfia (the local school). The students participated in both lidar measurements and launching the balloons for the NOAA balloon-sonde measurements.
JAN2010 Injectors replaced in E3 (the 600 kW generator-set that powers the ISR).
DEC2009 The National Space Center at Denmark's Technical University (DTU) has now taken over the Greenland magnetometer chain, as well as some of the other instruments DMI had deployed locally. These are now under the direction of our old friend Dr. Eigel Friis-Christensen and we are looking forward to many years of fruitful collaboration.
NOV2009 Run scheduled in conjunction with the new RISR-N (northward looking AMISR at Resolute Bay, Canada) in response to a predicted solar Corotation Interaction Region.
OCT2009 New engine replaces 26-year old original. This is one of two "house power" diesel generators, 180  kW each, used alternately to provide 24/7 power to the facility.
SEP2009 The Lytton klystron tube has been resurrected. After two weeks off-line to reconfigure the modulator socket, plumbing and electronics (and baking and tuning!), we are back on the air with the old spare klystron in ample time to perform the 10-day Equinox Wind Reversal world day run.
AUG2009 Anja Strømme takes over as Principal Investigator!
The CPI klystron has failed. This tube cannot be rebuilt again so the old Lytton tube will be installed. Fortunately, a new CPI klystron was ordered earlier this month with the special stimulus funding. It's scheduled for delivery June  2010.
Upgrades done by visitors on the HF Imaging system (Dartmouth College) and the CCD Spectrograph (Embry-Riddle Aeronautical University).
JUL2009 Eggert returns to Kellyville and resumes his position as site supervisor. He and Christian again team up with their EE design and implementation skills.
JUN2009 The German ambassador to Denmark, Dr. Christoph Jessen, and some of his staff come to Kellyville for a tour of the facility and instruments, including the German Weather Service particle samplers the site supports. As a thank you, Christian is hosted at a formal dinner.
MAY2009 New RADAC (RAdar Data ACquisition) system now on-line with three channels. This was concurrent with several modifications to the front-end of the receive path. The RADAC system was developed for the AMISRs and is used at PFISR and RISR-N. The addition of three more digital receiver channels is planned, which will allow for simultaneous measurements of both the up- and down-shifted plasma lines and the addition of light-ion measurements concurrent with the standard operating modes.
APR2009 The Danish Meteorological Institute (DMI) announces it has decided to withdraw from their activities in the field of geomagnetism, to be finalized by the end of this year.
MAR2009 The IPY (International Polar Year) which began in March 2007 has now ended. The 30-hour bi-weekly runs that we've been doing, coordinated with the other high-latitude ISRs, are now complete.
FEB2009 No Stratospheric Warming event has occurred this month, so no 10-day world day run for that.
JAN2009 Welcome aboard to John Fremming! John is a certified electrician from Denmark and will be a welcome addition to the crew.
DEC2008 Continuing with "normal" runs: bi-weekly IPY high-latitude ISR runs, Themis coverage coordinated with the HIRISE instrument for detection of the cusp, GUVI satellite overpasses, etc.
NOV2008 Two members of the Danish Parliament come to the site and have a tour.
OCT2008 Troubleshooting some strange symptoms and have traced it to a faulty internal switch in the exciter.
SEP2008 It was determined that one of the three elevation rotary joints has gone bad. It's been replaced with the good spare and is being returned to the US for repair/refurbishment.
AUG2008 University of Colorado, Boulder, graduate student Katelynn Greer finishes her six-week GSRE assignment working with the lidar systems. Katie's goals were to study PMCs and to test and characterize the the new polarization compensation components. In addition, she took over 100 hrs of usable data, including measurements of seven PMCs and evidence of aerosols from the eruption of the Okmok volcano in Alaska, all in spite of poor weather.
SR run will help determine if there are gravity waves caused by solar eclipse on 1 August.
JUL2008 Particle samplers near the site are installed by visitors from the German Weather Service, DWD (Deutscher Wetter Dienst), and the Karlsruhe Institute of Technology, Germany. The crew will perform periodic filter changes and posting.
JUN2008 After 12 years on-site, Eggert returns to Iceland -- he will be sorely missed. With the planned pull-out of DMI, Christian's position has disappeared but he has become an SRI employee and the new site supervisor.
