The countdown began at 15:00 local time, but weather conditions at all three optical sites did not favour a launch today. The countdown was cancelled at about 19:00.
The plots on this page show the current extent and position of the auroral oval at each pole, extrapolated from measurements taken during the most recent polar pass of the NOAA POES satellite.

The three hour countdown began at 15:00, local time. Local weather had improved since yesterdays count, and it was decided to elevate the launcher for the first time in this campaign.
But the desired launch conditions did not appear. The team conducted a horizontal test of the payload, and then the countdown was aborted at about 21:00, local time.

The weather forecast for northern Norway leaves no hope for a launch today, so campaign managers decided to cancel tonight´s countdown. The next countdown is scheduled for Saturday.
The Heater is used for ionospheric modification experiments applying high-power transmissions of high-frequency electro-magnetic waves to study plasma parameters in the ionosphere. The name Heating stems from the fact that these high power electromagnetic waves, which are transmitted into the ionosphre with high-gain atennas, heat the electrons and thus modify the plasma state. To create plasma turbulence, the transmitted frequencies have to be close to the plasma resonances, which are 4 to 8 MHz.

Weather and science conditions was very promising tonight, and the countdown progressed down to T-12 minutes before holding. All optical sites reported good conditions, but alas, the science conditions did not reach the desired levels.
The launch window was extended with an additional 20 minutes to allow for more time to evaluate the situation. Ultimately the countdown was cancelled at 23:20, local time.
Sunday 18 January 2009
The countdown began as usual at 15:00, local time. The vehicle was elevated to vertical position, and the countdown was paused at T-30 minutes.
Although clear skies over the optical sites for most of tonight, local wind at Andenes dictated that the vehicle had to be brought down in to the shelter again. The wind situation did not improve despite a one hour extension of the countdown, and it was decided to cancel the operation at local midnight.
Monday 19 January 2009
Countdown began at 15:00, local time and progressed down to T-1:30 and paused there for a while. Then, as science and launch conditions improved, the countdown continued down to T-12 minutes.
Today´s launch attempt was aborted at 23:30, local time.
Tuesday 20 January 2009
The countdown began at 17:00, local time and progressed down to T-1:30 and holding. Weather and science conditions chose not to cooperate tonight, and the launch vehicle had to remain in shelter. The operation was cancelled at about local midnight.
Thursday 22 January 2009
The three hour countdown began at 17:00, local time. The launch vehicle remained in shelter while waiting for a rain shower to pass the area. The rain travelled out to sea, however, and the S-310-39 was elevated to vertical position. The countdown held at T-30 minutes for several hours, waiting for the aurora - which didn´t appear at all tonight. Progressing down to T-12 minutes for the last couple of hours, the PI chose to abort the launch attempt at about 03:00, local time.

The campaign team enjoyed a day off.
Friday 23 January 2009
Countdown began at 17:00, local time. Local winds were to great for the launch vehicle to elevate, so the countdown held at T-1:30 for several hours before elevating the S-310-39 to vertical position and progressing down to T-30 minutes. With no hope for the desired science conditions to appear, the PI chose to abort the launch attempt at 01:30, local time.
Saturday 24 January 2009
Countdown began at 17:00, local time. The S-310-39 remained under shelter for the duration of the countdown. Some aurora appeared, but electron density was not up to the desired levels, and wind gusts exceeded safety limits. The PI decided to cancel the launch attempt at 02:30, local time.
