Not too warm maybe +7C or so..
One of the very first runs of the servo-lock of our ultrastable clock-laser to the clock-transition at 445 THz in 88Sr+.
+10C and sunshine.
+7C or so with a bit of wind and sunshine.
Some problems finding the 3rd control #62 having to loop around the larger paths to find it.
Warm maybe +7 C or so with sunshine.
Still people downhill skiing, although no lifts are running so you have to walk up the hill!
Despite the lockdown, some trapping in the lab this week. First single-ion experiments this year, after the 405 nm laser broke in January. Not much going on in these videos, but at least it's a single ion!
First clock-transition linewidth measurement give about a 200 Hz wide transition, so around 5e-13 fractionally.
Orienteering season 2020 opened. No arranged events, just controls in the forest without timing or punching.
Extra bends/loops just before 73 (nerves on the first control?) and after 58 - otherwise mostly ok. No compass! Around 56 minutes.
Meh.. just had this (lower M.2 drive in the pic) less than 4 year old (bought 2016/11) Intel 600p M.2 VNMe drive fail without any warning signs. The machine won't boot at all. Need to reinstall everything on a new (top drive in pic) 660p drive now...
