Wow. We know that collisions are not uncommon in the Asteroid Belt and much of what we find in that clutter of rocks is the aftermath of millions, if not billions, of collisions going back at least a couple of billion years. We just never get to see them. Asteroids are small.

Well, this looks like the aftermath of one heck of a collision. Check it out. Interesting.

Deciding Between The New Polar Vantage V & The Venerable Garmin Fenix 5.

‘Polar Vantage V’ & ‘Garmin Fenix 5 Plus’ Side-By-Side On My Wrist.





Price-wise they are $50 apart at Amazon (today), the new Polar Vantage V at $500 and the Garmin Fenix 5 at $450. [The Fenix 5 Plus is more expensive.]

In November 2018, when the Polar Vantage V came out, I was lucky enough to be given one to evaluate. I kept it for two weeks and wore it, ’24×7′ (bar charging time) for 11-days straight. Since I own a Garmin Fenix 5 Plus, and upgraded to that from a Garmin Fenix 5, I am pretty qualified to compare the two.

I have to say I was excited to get the Polar Vantage V. The early promotional matter made it very compelling. I was fairly convinced that I was going to ‘buy’ the evaluation unit and keep it.


The Polar Vantage V, with its bright, multicolor, touchscreen, 4-field display, is the perfect training watch. It really enhanced my running experience. I could see my heart rate, color-coded, at a glance, relative to its expected range – along with my pace, distance and time. Then using the up/down buttons I could quickly get altitude, ‘power’, heart rate data as well as the time-of-day. At the end of an activity (in my case a run), I was treated to a chock-a-block ‘training summary’ which included: distance, calories, heart rate zones, cardio load, pace/speed, speed zones, altitude change, power zones, cadence, etc. etc. It was like having a training COMPUTER on your wrist. And all of this on the watch – independent of the phone or computer APP.

It was pretty awesome. A level of (shareable) training data unmatched by any other watch I have used and I am no stranger to high-end Garmins, Fitbits and Samsungs.

As a sport watch the Polar Vantage V, in my experience, is in a new, crème de la crème, class of its own. Its GPS and heart rate data is consistent with what I have seen with my other high-end GPS watches – though its overall ‘step count’ appears to be about 20% too generous (probably because you can’t customize your actual stride length). That said, if you are a serious, dedicated athlete training for competitions, marathons, triathlons, Ironman or the Olympics, this very well might be the perfect watch for you.


The Polar Vantage V has two very different personalities – a ‘Dr. Jekyll and Mr. Hyde’ watch!

When in training-mode it is superlative. Probably peerless. THE watch to have. Period.

But, when in pre-training mode, i.e., when you are not training, it is a pretty pedestrian watch! In pre-training mode it is a pretty basic, uninspiring watch that does not tell you much. That is the rub. Hence, the need for very careful consideration. When not in training-mode it is a very boring watch!


That Polar does not call it a ‘smart watch’ is no accidental, oversight. The Vantage V is not a smart watch even by 2017 standards – let alone those of 2018 or 2019.

In pre-training mode it is insipid! There are no customizable, third-party watch faces with ‘bells-and-whistles’, nor widgets or APPs. There is no ‘ABC’ (i.e., altitude, barometer, compass), weather, sunrise/sunset, temperature, calendar or smart notifications from your phone. And I won’t even mention maps, music or credit/debit card payments. Oh, it also does not count/report floors climbed (i.e., altitude changes) when in pre-training mode.

While it does measure sleep time, there is no analysis in terms of whether it was REM or Deep. That is frustrating since I am used to getting that from Garmin and Fitbit. It is possible that Polar might add this ‘deep analysis’, at a later date, with a firmware update.


I thought about this long and hard.

On a scale of 1-to-10 determine the role and importance of training/fitness in your life. If you rate training/fitness at 7.5 or less, the Polar Vantage V might not be the right watch for you. If on the other hand, training/fitness figures as an 8.5 or above, definitely think about getting the V V. It would be a marriage made in heaven.

Another way to approach this is to determine your ‘training’ vs. ‘pre-training’ ratio, in terms of waking hours. If the ratio is greater than 50:50, in favor of training, the Polar V V very well could be the watch of your dreams. If on the other hand, training only accounts for 20%, or less, of your waking hours, you might want to consider a different watch — i.e., the all-round Garmin Fenix 5 (Plus).


The Polar Vantage V is possibly the ultimate sport watch currently on the market for pro athletes. Therein, however, lies the rub. If you are not a pro athlete this might be overkill for you. Get the Fenix 5 instead and you will be very happy.

So, the choice is straightforward. If training/fitness is a dominant feature of your life check out the Polar. On the other hand your life is more balanced wear a Fenix 5 with PRIDE.

ANOTHER Naked Eye Visible Comet Ahead Of Christmas 2018? C/2018 V1 (Machholz-Fujikawa-Iwamoto).

by Anura Guruge


Click to ENLARGE.


Comet C/2018 V1 ( Machholz-Fujikawa-Iwamoto )

Discovered: November 7, 2018 (yes, just last week).

Discoverers: One is Arizona (Donald E. Machholz, Jr.) & two in Japan (Shigehisa Fujikawa & Masayuki Iwamoto). You can find more here. Hence the name which credits all three.


C/2018 V1 is much more of a CLASSIC comet than our current ‘Christmas Comet of 2018‘, i.e., 46P/Wirtanen. That is why it has a ‘C/’ designation while the other is a ‘P/’. The ‘P/’ denotes that 46P/Wirtanen is a PERIODIC comet — one that swings around the sun on a regular basis (like a commuter). The ‘C/’, on the other hand, means that is a NON-PERIODIC. It means that this comet has not been previously seen in the last 200-years. Typically it means that it is a FIRST TIME visitor from far, far out in the Solar System, ideally from the Oort Cloud, the incubator of most comets at the very edge of our Solar System.

So, we are assuming it is a FRESH comet, with a lot of frozen matter that will sublimate as the comet gets closer and closer to the Sun. That is what makes it visible, gives it a tail and with luck makes it spectacular. Right now it is touch and go. Viewed through a powerful telescope you can already see a blue tail — that color indicating the presence of ionized Carbon Monoxide (CO+).

On Tuesday, November 27, 2018 it will be at its closest to Earth — 62 million miles. Comet ISON (C/2012 S1) that could have been the GREAT COMET of 2013 would have been 40 million miles. So, C/2018 V1 will be 22 million miles further out. BUT, unlike ISON it will make it around the Sun. That is a given. It is NOT a sungrazer. Actually it doesn’t get very close to the Sun! As you can see from the above diagram it does not even cross Mercury’s orbit.

Right now it is BORDERLINE — but shows more promise than 46P.

I will keep you posted. This was a BIG heads up.


Comet ISON IF it had rounded the Sun — rather than getting FRIED by it, because it went so close.

I got the download when I connected it to my Windows PC, via USB, to charge it up.

I can’t find anything about this update on the Web — BUT it is on my watch.

So, just wanted to give you a heads up.

Download and install was pretty fast. Had to restart the watch.

I just got the November 2018 issue today and only had time to quickly scan through the article and BEAUTIFUL photos.

It is a topic dear to my heart since I have seen, first hand, this year, as to what is happening to TRIBAL LANDS.

The “Bad Ol’ Days” are back again with the Indians, yet again, with their backs to the wall.

My concern was what was happening at Canyon de Chelly.

The NatG article is mainly about Utah and “Bears Ears“.

Please try to read this article. Hence, this post. Thank YOU.
