I will grant that this new comet, C/2019 Q4 (Borisov), does have more of an intriguing orbital path than did C/2017 U1.

But, I am not willing to RUSH to the conclusion that it is interstellar — i.e., it did NOT originate in our own Oort cloud. Still very early days. That it is travelling too fast to be bound to the Sun is interesting.

I was not convinced about A/2017 U1 (ʻOumuamua) being interstellar and now others are joining in. SMILE. I do know some about comets.

All I am saying, for now, is don’t rush to a conclusion. Let’s study this puppy a bit more.

Definitely not going to be GREAT comet. It will be very far from the Sun. Twice as far as the Earth is to the Sun. So, unlikely that it will be very bright or sport a spectacular tail.

Just wanted to keep YOU in the loop. But, stay tuned.


Has a ton of good information about comets.

‘Black Moon’ Today, July 31, 2019, & How It Differs From A ‘Blue Moon’.

by Anura Guruge




The Key Difference:

Black Moon has to be a NEW Moon.

Blue Moon has to a FULL Moon.

Other than that they both refer to an ‘EXTRA’ moon in a given ‘month’.


Blue Moon‘ can mean one of two things:

1. Second full moon within the same calendar month.

2. Third full moon during an astronomical season that has four full moons; an astronomical season in this context being the 3-month period between an equinox and a solstice, e.g., 3-months between the March Spring Equinox and the June Summer Solstice.


Black Moon‘, DITTO, but when it applies to a NEW MOON.

So, it means:

1. Second NEW moon within the same calendar month — as is the case this month, i.e., July 2019.

2. Third NEW moon during an astronomical season that has four full moons; an astronomical season in this context being the 3-month period between an equinox and a solstice, e.g., 3-months between the March Spring Equinox and the June Summer Solstice.


Both are rare events.

Furthermore, today’s Black Moon is a Supermoon — i.e., it is closer to Earth than normal.

Did You Know That ‘AOC’, Alexandria Ocasio-Cortez, Has An Asteroid Named After Her?

by Anura Guruge


Donald Trump will be SO, SO livid IF he ever finds out.

So don’t tell him. OK? Our secret.


23238 Ocasio-Cortez (2000 WU111)

This wasn’t recent either! It was named after her c. 2007 — eleven years ahead of her being elected to the United States House of Representatives.

This is pretty impressive stuff. She got this honor, because as a high school senior (aged 18), from Yorktown High School [Yorktown Heights, New York], in 2007, she won second place in the 2007 ‘Intel International Science and Engineering Fair’ for her microbiology project. Wow.

I really don’t know much about her. Did not even suspect this.

Trump will now want Jupiter renamed after him. But, maybe NOT Jupiter. Mars would be more appropriate and it is a GOOD COLOR match.


The asteroid itself had been discovered in 2000 at the Lincoln Laboratory.

A pretty common or garden asteroid in the asteroid belt. Nothing special. Decent size. Just over a mile across. So, not huge, but not tiny either.

Pretty close to noon this year.
Kind of neat.
Most of us will be able to watch for it.

IF you pay real close attention
you can feel the Earth making the turn!

Plus 

MY LEAST FAVORITE DAY OF THE YEAR!

Days start getting shorter — and I hate that.

To I, it means Winter is on the way.

11:54 am Eastern in the USA — 15:54 (or 03:54 pm) GMT.

Jupiter Over New Hampshire: At Its Closest For 2019, Next Week; Largest Moons Visible With Binoculars.

by Anura Guruge

Weather Will Permit.

Click to ENLARGE. From: wunderground.com for Central New Hampshire.


Every year, given the orbital dynamics, the Earth and Jupiter are atypically close for a period of around 3-weeks. This year, Jupiter will be closest to Earth next week, i.e., mid-June, 2019.

When it is this close Jupiter is only 365 million miles away. At its furthest it is 601 million miles out. So, that is quite a variance.

It will be so close that you will be able to see Jupiter’s largest satellites with just binoculars. (Jupiter currently has 79 known moons!) Watching Jupiter’s moons is ALWAYS cool and being able to do so with binoculars is a bonus. Much easier than trying to follow them with an ametuer telescope (and trust me, I have).

The weather will cooperate on at least some of the days. So, make sure to check. Showers during the day and still give us cloudless nights.

Enjoy.

2019 Spring Equinox In New Hampshire: Wednesday, March 20 at 5:58 pm (Eastern); 21:58 Greenwich.

Happy Spring Equinox 2019.

[It is also called the Vernal Equinox
— that being the Latin for ‘Spring’.]

Click to ENLARGE.


I also share with you “Spring“.

Please enjoy.


Sunrise/Sunset for New Hampshire as of the
2019 Spring Equinox.

Notice that it is NOT EXACTLY 12 hours of sunlight on the Equinox.
That is mainly because we are so good at measuring time.
It has to do with the so called precession of the Earth’s axis.
Our rotation WOBBLES like a spinning top.
