Day Thirteen - The data keeps coming...
The second PAMS run today. The Japanese are in the middle of their experiment which runs well into tonight and so scuppers any chance of FACE and DROP. This is not such a loss since the cloud is now back and the forecast has returned to rain. I am able to run PAMS only as it is a VHF experiment and does not interfere with the Japanese.
Andrew volunteered to get up and start PAMS for me since I had been up for ~20 hours straight yesterday. He didn't seem to think that operating on 2-3 hours sleep after that was a good idea. I relieved him at 8:30 and he has gone back to bed. We were thinking of hitting the ARIES site later to do repairs but with a combination of knackeredness and potential rain, we are unsure now.
The data for today's PAMS run is not as good as yesterday. It started with a strong, precipitation induced D layer but that disappered soon afterwards. We also have lots of meteor effects (we think) and a strange 'line' running across at ~100 km altitude in the form of a sharpish gradient in the electron density. Need to investigate that, it appeared yesterday as well. Pretty quiet overall. All ULF activity is north of Tromso according to the magnetograms and surprisingly little in the way of drifting precipitation patches.
PAMS ended at 08:30 UT with a load bang and flash of the lights as the UHF crowbarred. This has happened a few times today, three of them caused the VHF to go down as well.
Right, I'm off back to bed. Summary plots of the data collected so far will apear in due course. We are not sure where yet. The RAL campaign site is a possibility, I will have a fiddle with it later. It seems overly complicated. Whatever happened to the days of bashing out a few lines of html? ;-)
