1. No copy/paste? No context? No content?

There ought to be a pinned post, "How to do DU."

2. Better?

3. What? Another contentless link?

Some of us do not have unlimited download. So we eschew such posts as yours which post mere links with no context, or even what the post is about.

Where I live there is not only no cable TV, but no internet broadband. I live on 5GB download per month only because I happen to have a cellular tower close enough here in the Manistee National Forest to get two bars on my iPhone. Otherwise I would have only dial-up!

So clicking through on a contentless DU OP is not an option. And I very much resent clicking through to such lazy posts. If one cares enough to make an OP, at least provide a requisite four paragraph synopsis.

Otherwise, the post is useless to many of us.

Sorry, my friend. That's the way it is in some places (apparently not where you are).

4. Sorry you don't have access to my posts. There are photos, if you could see them. I'm in Southern MD

'Have you heard about the huge coronal hole in the sun that is facing Earth’s way? According to spaceweather.com, it means the chances of geomagnetic storms (think of them as disturbances in the force!) and thus auroras for those at high latitudes are high this week. Should you be worried? No. The Space Weather Prediction Center calls this a “minor” storm. Astronomer Tony Phillips, who writes Spaceweather.com, wrote on January 3, 2017:

NOAA forecasters have boosted the odds of polar geomagnetic storms on January 4 and 5 to 65% as a stream of solar wind approaches Earth. The hot wind is flowing from a large hole in the sun’s atmosphere.

[The image above], from NASA’s Solar Dynamics Observatory, shows the yawning structure almost directly facing Earth on January 3.

Astronomer Karl Battams (@sungrazercomets on Twitter) explained coronal holes today in his Twitter feed:

The sun is mostly covered in lots of ‘closed’ magnetic fields … In coronal holes, the fields are ‘open’ out to space.

Tony Phillips (@spaceweather on Twitter) explained:

Coronal holes are regions where the sun’s magnetic field peels back and allows solar wind to escape … Residents of the Arctic should expect G1-class geomagnetic storms and bright auroras in the nights ahead.

Okay so … will you see auroras? That depends on where you live. At this writing, the Space Weather Prediction Center is calling for auroras at 60 degrees N. and further northward, with possible aurora sightings at the latitude of the northern United States – for example, in Michigan or Maine – on the nights of January 4 and 5, 2017. Be sure to check for updates!'>>>

5. I have access to your contentless posts.

But clicking off site pays a rather severe penalty. Thankfully DU is a very efficient site, mostly text and very efficient with respect to download. I can surf all day here and still have plenty of download to spare. Not so to click through to other sites. That's why I find posts like yours to be utterly useless. There's no fucking content or context, in other words an entirely useless post.

Us limited Web surfers are acutely aware of such things. Unfortunately those with unlimited INet are not.

And thank you for filling in context. I have a degree in physics so this interests me. Just did not want to click through without context.

My best to you. Please don't post OPs without at least a commentary, or quotation, on the content.


On edit: thank you very much.
