The K7RA Solar Update

This past week, there was a decline in the solar and geomagnetic indices: The average daily sunspot number dropped nearly 21 points to 57.7, while the average daily solar flux softened by 4.7 points to 100.9 and the average daily planetary A index declined 6.4 points to 5.1. This isn’t much of a change, but geomagnetic activity was low already, and this is even lower.

One of the best single serving beverage ideas I have seen in a long time. These Starbucks Discoveries lattes come in a variety of flavors and sell for about at convenience stores. They come with a foil lid under a plastic lid, which allows you to insert a collapsible straw through both layers and not make a mess. This is by far the best flavor–I love this. I wish they sold it in the States.

It should be noted that the tower is so balanced that initially I have to assist it by pulling at the bottom of it to start in going over. Additionally, there is so little weight against the cables that I have to be sure to keep the cable tracking in the pulleys until there is sufficient weight to keep them in the tracks. When I raise it the wench assumes greater torque at a point where the ratcheting mechanism finally begins to engage so that I have to adjust the ratchet trigger to the proper setting. The whole process is weightless and easy to do for the user.
