Solar scientists predict a major decline in sunspot activity

1:37 pm

At a press conference today at the 2011 meeting of the Solar Physics Division (SPD) of the American Astronomical Society (AAS) in Las Cruces, New Mexico, solar scientists predicted that not only will the next solar maximum in 2013 be the weakest in centuries, it is very likely that it will be followed by another long Maunder Minimum, a period of decades without sunspots. “The sun may be going into hiatus,” says Dr. Frank Hill, associate director of the NSO’s Solar Synoptic Network. You can read the press releases for this announcement here and here.

decline in magnetic field over the last few cycles

These conclusions are based on three lines of evidence:

  • There has been a long term weakening in the magnetic strength that produces sunspots themselves. The declining trend suggests that by 2022 it will no longer be strong enough to produce sunspots. The graph above shows this decline.

Obamacare doesn’t stop Medigap providers, AARP partners from discriminating against seniors

11:31 am

Surprise, surprise! Obamacare doesn’t stop Medigap providers and AARP from discriminating against seniors with preexisting conditions, as had been promised.

This story is just more evidence that the law is a mess, it should never have been passed, and in the future our so-called lawmakers should read the goddamn legislation before they vote on it.

I should add that I think it a very big mistake for the government to forbid insurance companies from denying new coverage to sick individuals. If insurance companies are forced to accept everyone as a new customer, even those who are ill, why bother paying for insurance when you are healthy? Everyone can simply wait until they are sick, and then buy the coverage, thereby getting a lot of insurance for very little investment. The result: insurance companies go bankrupt, as the whole concept of insurance depends on a lot of healthy customers paying the cost, at a low rate, for those who are sick.

Robot refueling test of satellites to be launched on last shuttle flight

10:09 pm

A testbed for testing the robotic refueling of satellites will be installed on ISS on last shuttle flight.

This whole testbed is the brainchild of Frank Cepollina, the man behind all of the Hubble Space Telescope repair missions. Until recently it was doubtful there was room for this project on any shuttle mission. That he nonetheless managed to get it on the last flight is another testament to Cepollina’s incredible ability to get things done. And if the tests work on ISS, NASA will then consider launching operational systems for refueling several perfectly usable climate satellites now in orbit.
