   The saga of the Chevy Volt in cold climate conditions continues!Today's adventure: the window on the passenger-side front door got stuck in the down position. This seems to be a result of the utter failure of the window regulator.Parts have to come from US. Mechanic hacked the door to keep the window up by clever use of vice grips in the panel (tape in cold weather leaves QUITE a film, so not an option). Will be like this for 1-2 weeks.Please ... no more failures. #FailureIsAlwaysAnOption

   A look back at the last week of weather, from the perspective of my weather station. What a week! We saw air temperatures down to -34C preceded by wind speeds up to 43 km/h. At one point, wind chills got to around -40C which … fun fact … is also equal to -40F. So I also got to see the equivalence point of the Celsius and Fahrenheit scales! Quite a week! https://chirp.cooleysekula.net/attachment/05bcfb4ed1526de80162396037434874bdd9f13e1c450680da33514fab05024e/view

   From NASASun https://twitter.com/NASASun on Twitter: So what’s the difference? A solar flare is a powerful burst of energy that can be spotted as a sudden flash of light. Fun fact: Traveling at the speed of light, the energy from flares can take 8 minutes to reach Earth! https://twitter.com/NASASun/status/1621920359887822848/photo/1 https://chirp.cooleysekula.net/attachment/8a2e7a58de8bf93188024a90846aa70c15254bafdd2c58c985ec9b134c3d5bd8/view

   From NASASun https://twitter.com/NASASun on Twitter: Eruptions on the Sun differ in how they look, how they travel, and even in the way they impact us here on Earth. Solar flares and coronal mass ejections (CMEs) both involve enormous explosions of energy – and at times may even occur simultaneously. https://twitter.com/NASASun/status/1621920326882934784/photo/1 https://chirp.cooleysekula.net/attachment/45afd5aa366efe666639b548edcb19ac7aba1b707db959824ba4973d03d8c370/view

    Polar air has descended on Ontario and real winter has finally arrived! We had some lovely 24 km/hr wind gusts today, falling snow, and temperatures with wind chill approaching -30C. The temperatures without wind chill will sit around -25C - -30C tomorrow. This is the winter I was promised. This is the winter I bought a serious coat for. :-) https://chirp.cooleysekula.net/url/139511

    Had an awesome day in the underground lab yesterday working with PICO colleagues on one of the experiment's chiller systems. It has been almost 2 months since I went underground due to surface demands, so it took some re-acclimation. But as always, it was AMAZING. Working on a dark matter experiment 6800ft under the earth is quite an experience. For most people at SNOLAB, it's every day of their regular job. For the miners in the active mine around us, it's even more incredible.

      Getting to SNOLAB has two steps. The first is a "cage ride" from surface to the 6800ft level. For that, and the 1.4km walk from the cage station to the lab, we are required to wear standard mine personal protective equipment: high-reflectivity coveralls (bright orange), boots with toe crush protection, gloves, eye protection, hard hat, ear protection, and a cap lamp. The mine is about 27C (80F).
      
      At the lab, we remove all mine clothing, shower, and change into cleanroom suits, hairnets. A chiller maintains the lab at 20C (68F). The lab is a class 1000 cleanroom.

      @steve If it weren't cool and interesting enough science this is even incredible. Thanks for the link to the video. I guess you can become used to it but from outside is wow!, for the lack of a better expression in my vocabulary.
