Title: Solar Minimum
Post by: ChrisSmolinski on May 12, 2017, 1238 UTC
Looks like we're definitely about to enter solar minimum (not that solar maximum was really that... maximum this cycle). 10.7 cm solar flux is just 69 right now. While that may not sound low, the lowest ever recorded value was 64, and during solar maximum solar flux approaches and sometimes exceeds 250. 
 
"For the third day in a row, the sun is blank--no sunspots. This marks the 32nd day in 2017 that the sun has been without spots. Cumulatively, it adds up to more than a month of blank suns--and it's only May. For comparison, it took all 12 months of 2016 for the sun to accumulate 32 spotless days. The accelerating pace of spotlessness is a sign that Solar Minimum is approaching. "

I guess the bright side is it should only get better from here?

In a few years. Except forecasts (which don't have a great track record) are for an even weaker Cycle 25 than the current Cycle 24.

According to the space weather news the sunspot nadir (lowest point) will be in 2019-2020.  :'(

Not looking forward to 2019-2020 then. 

Looks like 11 meters is going to be sporadic-E only for a while, if anything at all.  I wonder if sales of export radios and modified CB equipment will slow down with the solar minimum.

The sun seems to be taking care of all that globular warmins.

Just today I ran across this graph of solar activity going back 11,400 years. It's interesting how solar activity in the last century has been much higher than the historical average (and that this coincided with the invention of radio). Should we regress back to previous activity, we might all become longwave DXers  ;D

This is what I have been saying for over the past 20 years or so...  Do Not Sell The SUN Pimple Cream!!!

I left Maine because I had a dream... a dream in which my little farm would be under 10 feet of permafrost,  and my little veggie garden would be no more...  My many varieties of Roses would be nothing more than frozen sticks and my Nutz...  well... let's not go there OK?

And so much worse would be the fact that my Out-house would be completely frozen over and me with no place to go...!  damn you Sun...

"Black Hole Sun won't you come and wash away the stench, Black Hole Sun won't you come won't you come"

heh

^^^^^^^ So your dream consisted of Maunder Minimum / Little Ice Age fears?

Hopefully, it doesn't happen, if only for the world food supply.

I thought we were AT solar minimum already...
I really don't want to see any solar minimum any more minimum than we have now, sheesh.

I'll need a trailer to haul the loading coils for that long-wave antenna...

Seems like for years now we keep hearing we're at the stupid minimum.

As far as a trailer for loading coils... assuming conventional antennas. Perhaps time to research other methods of transmission for these wavelengths. Or take out stock in trailer manufacturers.

So the theory of a Solar "Maunder" Minimum lasting for 70 years is unfounded??

Time to get LORAN-C/eLORAN online, and bring back Omega.

Ugh!  I thought we were already *at* the darn solar minimum...  :( 

KA1IIC, no offense to you, but I absolutely *loathe* that song, parody snippet or no parody snippet!  Gag!  It makes my ears revolt, or want to.

Don't know about that, but I suspect the sale of 8 pill and higher linear amps will go up.  ;D

*eyes the news* Re: that revolting Sound Garden song...  I should not have said a word, should I?  Didn't know anything had happened to the lead singer at the time I posted, but I still feel like something of a heel now.

I'm a fan but I perceived no insensitivity in your remark. I figured you hadn't heard the news when you posted. I don't think it had broken yet. I only heard this morning myself.

People are dying today that never died before. Like poor old Roger Ailes. I heard Satan and Franco were waiting for him at the gates of Hell. They figure if he could get Nixon elected in 1968, it would be a cinch for him to get them out of their predicaments.

Cheers, MDK2. 

Pigmeat, I should not have laughed at that last... but oh brother, did I!

When you make dead guy jokes you've got to consider the reputation of the man along with the timing, Chanter. Posting a joke about Ailes going to Hell and using his skills to help Satan and Franco wouldn't have the same punch if I'd waited until he was in the ground.

I give all you folks permission to laugh your buttocks off when I kick off :-)

And the jokes... anything goes unless it messes with the HFU policy...  off line everything goes :-)

I believe in eternal life...  And if the theories hold up that you can't destroy energy... Well I'll go tap dancing on a lot of graves...  Prepare for a tap tap tap to all in a box below the ground.

As for my dead husk...  I, like George Carlin, want to be blown up... not in a box, or burned, toss a few holy handy-grrr-naids me... Get drunk and have a BBQ and smoke some pan...  errrr... pot?

man.... where the hell is my medication...  suddenly feeling dizzy...   arg.... <<<<thud>>>>

You have never struck me as someone who would be insensitive like that. Like MDK2 I figured you hadn't heard the news yet.

No offense taken here, and I'm a Soundgarden fan.

Chris Cornell, RIP....
