      Minnesota Fishing Report Clubs - ONLY 20 FREE MEMBERSHIPS Per Area - Join Today - FREE   03/08/2018

      Fishing Minnesota has added a new menu item (see above) called Fishing Report Clubs. It's a way to keep the really good fishing reports coming and being shared only with those who also provide detailed fishing reports. We will only approve new members who request to join if they have already posted a recent fishing report in the area forum, associated with the Fishing Report Club area  you want to join. Initially we are going to limit the number of regular memberships, in the Fishing Report Clubs, to the top 20 members in each Club, to those with the best frequency and quality fishing reports provided in the club and less so in the regular fishing report forum open to all members. The higher quality fishing report reserved for the club of course. If  you want see detailed fishing reports/tips  around your area and will share your detailed fishing report as soon as you join, then Join Now! Some of the clubs are starting to fill fast. Use the Fishing Reports Club link in the Menu above (after you've posted a fishing report in the regular area forum) and request to Join.

    You know what we all love...

    When you enchant people, you fill them with delight and yourself in return. Have Fun!!!

Solar Bursts May Threaten GPS

Apr 4 02:16 PM US/Eastern


AP Science Writer

WASHINGTON (AP) - The Global Positioning System, relied on for everything from navigating cars and airplanes to transferring money between banks, may be threatened by powerful solar flares, a panel of scientists warned Wednesday.

"Our increasingly technologically dependent society is becoming increasingly vulnerable to space weather," David L. Johnson, director of the National Weather Service, said at a briefing.

GPS receivers have become widely used in recent years, using satellite signals in navigating airplanes, ships and automobiles, and in using cell phones, mining, surveying and many other commercial uses.

Indeed, banks use the system to synchronize money transfers, "so space weather can affect all of us, right down to our wallet," said Anthea J. Coster, an atmospheric scientist at the Haystack Observatory of the Massachusetts Institute of Technology.

The cause for their concern, Johnson said, was an unexpected solar radio burst on Dec. 6 that affected virtually every GPS receiver on the lighted half of Earth. Some receivers had a reduction in accuracy while others completely lost the ability to determine position, he said.

Solar activity rises and falls in 11-year cycles, with the next peak expected in 2011.

If that increasing level of activity produces more such radio bursts the GPS system could be seriously affected, the researchers said.

And protecting the system is no simple task, added Paul M. Kintner Jr., a professor of electrical engineering at Cornell University, who monitored the December event.

There are two possible ways to shield the system, he said, both very expensive. Either alter all GPS antennas to screen out solar signals or replace all of the GPS satellites with ones that broadcast a stronger signal.

That's why it's essential to learn more about the sun's behavior quickly in an effort to find ways to predict such events, the researchers said.

In addition to the GPS system, the December solar flare affected satellites and induced unexpected currents in the electrical grid, Johnson said.

"The effects were more profound than we expected and more widespread than we expected," added Kintner.

Dale E. Gary, chairman of the physics department of the New Jersey Institute of Technology, said the burst produced 10 times more radio noise than any burst previously recorded.

The difference between that burst and normal solar radio emissions "was like the difference between the noise level of a normal conversation and the noise level in the front row of a rock concert," he said.

"This is a wake-up call" to improve technology, commented Anthony J. Mannucci, group supervisor at NASA's Jet Propulsion Laboratory.

Patricia H. Doherty, co-director of the Institute for Scientific Research at Boston College, said the burst affected but did not shut down the Federal Aviation Administration's Wide Area Augmentation System, which uses GPS signals to assist in navigation.

Most of the WAAS ground stations were able to maintain contact with enough satellites to continue working, though their accuracy was somewhat affected, she said.

The stations have to maintain contact with at least four satellites to work, but usually monitor at least 10 to increase their accuracy, she said. Most were able to meet the minimum, she said.

The briefing came at a Space Weather Enterprise Forum convened by the National Oceanic and Atmospheric Administration to discuss the effects of solar activity. Because of its increasing importance, Johnson said, the Weather Service's Space Environment Center was converted from a mainly research center in 2005 to an operational center reporting on solar activity and its impacts.

This be why I missed all that hot crappie bite last month?

Or was it that 12 pack of MGD's? grin.gif

Random guy

Could you imigine Upper Red Lake Friday night about mid winter in the dark and all the GPS went down? shocked.gif We would have trucks and wheel houses crashing, driving across the line, just doing circles, drilling in three feet of water so on and so forth. It would be one heck of show.

      True dat!  Ducer slides right next to the ice. I did fish in a couple 8 inch holes yesturday for a couple minutes after some guys left. Almost felt like i needed a life jacket on!! Lol

      I'm so jealous of you guys, I put my ice fishing gear away couple nights ago. It took 3 Busch lights and and one Keystone light tall boy to muster up the courage to pack it away till next winter. Sad day.

      Spent some time on on Francis today. Ice on the main part of the lake looks to be in great shape but the west access is pretty bad. Got the ATV out, Probably not getting a vehicle out though. Saw one car out, don’t know where they got on the ice. Shore isn’t pulling away yet (other than the access).

      You hole hop like me or the guys I fish with you just added another 50 holes or better to your day doubleing them up for transducers. Rarely do we plop down in one spot unless its lights out! 
    • Mike89
      just don't eat the smart pills the bunny leaves behind!!!!
    • Mike89
      easy to cut the 6" and eye guy, like me is getting older!!!     besides a 2nd hole beside the first is where the transducer goes!!!
    • smurfy
      i'm trying to finagle a weekend up there one last ice fishing hurrah, how the lakes lookin? not interested in truck travel, just ATV.  rumor has it gunners headed back south soon so it should be safe for me to head that way.  lookin at he weekend after da easter bunny comes!!!!!!!
    • IceHawk
      Agree 6 inch is defiantely the way to go for panfish especially when running gunning. But I'm a 8 inch guy like that little extra room as I rarely pull the transducer when iceing panfish.  I'm also a big walleye guy so that really helps landing fish! The one thing bad about you  6 inch guys is that I cant crack the top of your old holes very easy with my 8 Lol!

      Fortunately I am set Boat is rigged to max. Maxed out thrust wise on front and the back trolling motors. Elite 7, Hook 7, vexilar fl18 in back. Front X 15. Definitely a Lowrance man. If that doesn't find me fish then  I might as well hang it up lol!  Maybe  get rid of my butt seat buy a new pro pole seat with the flip seat to lean on a little more. As far as gear Have my eyes on a Engel Bait cooler probably pull the trigger on one of those as they look good and have heard good things about them . Oh was down at the NW Sportshow today and added a new Okuma. Definitely didn't need a new one but  u know how it goes   Very tempted to break out the wallet a few times but resisted temptation. LOL ! Odds and ends here there but major purchases are done for a bit.

      I do not mean to ruffle feathers but if a fish is not indigenous to a lake isn't that like introducing an invasive species?
