      The solar wind speed is slowing down since the most recent coronal
      hole encounter, and things are getting quite, well, boring. The is
      but a lone sunspot region visible, and it seems to be rapidly fading.
      Expect things to be pretty quiet for the next few days. The most
      interesting thing for the time being is the upcoming transit of Venus
      across the sun on 6/8. Nobody alive on Earth has seen this happen.
      The last time it happened was 1882. Unfortunately for us in North
      America, the event will in it's latter stages when the sun rises. It
      will be visible for a couple of hours after sunrise on the east coast,
      and if you're a night owl or an early riser, you can watch the event
      live via webcam from many locations in across the pond. See
      www.spaceweather.com for more information.
