First Comet ATLAS, Then Comet SWAN & Now C/2020 F3 (NEOWISE) — A Possible Naked-Eye Comet.

Don’t get your hopes up. We have already had two duds, i.e., ATLAS & SWAN.

This one could be even more elusive. It was discovered a few days BEFORE SWAN.

It went by us once already. Though quite close to the Sun right now, it is VERY FAINT. Nowhere close to naked-eye right now.

But … a month from now. It could be a different story.

I will keep an eye on it, for you. Rest assured.

I Finally Manage To Get A Book Listed By ‘Apple’. Wow. It Has Taken Me 10-Years!

by Anura Guruge


Click to ENLARGE.


I am in shock. I had kind of given up on ever getting a book on ‘Apple Books‘.

I had tried & tried & tried over the years — since 2010. They just make you jump through so many hoops. I would eventually give up, given that Amazon Kindle eBooks can be read on Apple devices. Kindle eBooks can be read ANYWHERE. So, that was my rationale; my excuse.

My latest book, i.e., “Comets“, even if it is just I saying so, is rather ‘special’. SMILE. I wanted to make it as widely available as possible.

So, I worked with ‘Draft2Digital‘. It still took me three (3) attempts. Finally I sorted out all the wrinkles & managed to meet all the criteria. Bingo. Apple accepeted it.

Whether I will sell even a single copy is a different matter. At least now I have broken my duck. Wow.

I am in shock.

As Comet C/2020 F8 (SWAN) Makes Its Flacid Swansong, I Bring You Comet C/2017 K2.

As I say in my ‘Comets’ book it is a very atypical comet.

Read the little blurb on it.

More on this comet in the coming days.

Comet C/2020 F8 (SWAN): Very Low & Barely Naked-Eye In The Night Sky, In The U.S.

by Anura Guruge


Click to ENLARGE.


So, this is where it was at 11pm tonight, i.e., Friday, May 29, 2020.

It brightness, in ‘absolute magnitude’, is DOWN to +6. That is NOT good. That is borderline naked-eye visible.

So, I am NOT expecting C/2020 F8 (SWAN), alas, to be a BIG hit. I, after the collapse of ‘ATLAS‘, was ultra-cautious. I did not want to build-up, false expectations.

But, I will keep you posted.

You might want to check out my new ‘Comets’ book — published yesterday!

“Comets” — THE Book.

The title tells you everything you need to know. Comets.

If you insist this is the ‘Table of Contents’.

As I always say with my book, use Amazon’s FREE ‘Look Inside‘ feature to TEST DRIVE it. Plus, Amazon lets you read the book & then RETURN it. No questions asked. Full refund. So, what have you got to lose?

I have shared some of the 61 full-color figures — not counting a number of info-packed tables.

This is how I spent the last 5-weeks.

I was trying to beat quite the deadline. Comet SWAN might be naked-eye visible as of next week. I wanted this book, published, prior to that. And comets travel fast! SMILE.

Well, this will be one of the ways I will remember the pandemic. “Ah! Yes. That is when I wrote that Comet book“.

Oh, NOT my first comet book. Actually my 4th. That helped. I knew, by rote, 70% of the material.

Comet C/2020 F8 (SWAN) Still Elusive In The North, Though It Put On Quite The Show ‘Down Below’.

by Anura Guruge



It is BARELY naked-eye visible in the North — and it is very low, in the very early mornings — in the NW sky.

Very low & borderline naked-eye.

It could — it should get — brighter. Perihelion is on May 27, 2010. 10-days away.

On May 13 it was at its closest to Earth.

Fingers crossed. It is up there. Just not that visible.

This has been the story, when it comes to comets, in the Northern Hemisphere.

New Comet C/2020 F8 (SWAN) Looks VERY Promising, BUT Will Not Be Seen In The North Till Next Week.

by Anura Guruge


Click to ENLARGE.


Comet SWAN, i.e., C/2020 F8 (SWAN), has become naked-eye visible in the Southern Hemisphere. It is approaching us from below the equator. Hence, why it is currently only visible in the South.

This will change as of May 11, 2020. It will cross the ‘equator’ — so to speak. The ‘Ecliptic‘ if you want to get technical. It will still take a few days after that to get above the horizon and trees.

I will keep you posted.

Keep your fingers crossed that this one, unlike C/2019 Y4 (ATLAS), will NOT fragment and fizzle away.

The ‘Eccentricity’ Of New Comet C/2020 F8 (SWAN) Is Very High, But This Could Change With More Observations.

by Anura Guruge


Click to ENLARGE.


It has NOT been deemed Interstellar — i.e., originating from outside our Solar System.

But, the eccentricity — pretty damn close to ‘1.0’ — and the CRAZY 10 MILLION YEAR orbital period suggest that this is a strange comet — for NOW.

But, we only have 90 observations of it yet. Basically, early days.

With more observations the orbital path will get REFINED and will most likely change.

Just wanted to make sure you got that.

New, Promising Comet C/2020 F8 (SWAN) VS. C/2019 Y4 (ATLAS) That Has Fizzled.

by Anura Guruge


Click to ENLARGE.



C/2020 F8 (SWAN) definitely has promise & potential. But, you saw what happened to C/2019 Y4 (ATLAS). So, let’s give this one another couple of weeks before we get too excited. Yes, I will, of course, monitor progress and keep you posted. Promise. We will definitely know by end of April.

Comet C/2020 F8 (SWAN) Steps In As Naked-Eye Candidate C/2019 Y4 (ATLAS) Fizzles.

by Anura Guruge


Click to ENLARGE.


A brand new comet, discovered in March 2020 — hence the ‘2020 F’ (6th half-month of 2020).

SWAN denotes that it was found by the Solar Wind ANisotropies (SWAN) instrument of the SOHO spacecraft studying the Sun.

Its perihelion date is May 27, 2020.

It could become naked-eye visible in a few weeks. I will keep YOU posted. Promise.
