Far from attracting general attention, let alone vying for ‘greatness’.

But, early days. Dawn comets, somehow, don’t cut the mustard unless they are truly spectacular & NEOWISE is far from that.

But, this could change. Just wanted to keep you apprised.

4,000th Comet Discovered Using Digital Images Provided By NASA/ESA SOHO.

From my “Comets” book
(shown below).

The above two extracts from my “Comets” book tell you everything you need to know. SMILE.

NASA/ESA SOHO makes available digital images that amateurs can scan at their leisure to spot comets.

The 3,000th comet thus discovered was made in September 2015.

So just under 5-years to find another 1,000. That is 200 a year. NOT BAD.

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

by Anura Guruge


Click to ENLARGE.


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.

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.

by Anura Guruge


Click to ENLARGE.






Click to access the Amazon listing.



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

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


Click to ENLARGE.


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


Click to ENLARGE.

By Diego Toscan, in Argentina — and it looks like it was shot with a telescope.



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.

Fragments Of Comet C/2019 Y4 (ATLAS) Start To Brighten, Per Ace Comet Hunter Terry Lovejoy.

by Anura Guruge


Click to ENLARGE.





The first set of imaging is by veteran comet hunter Terry Lovejoy — who has discovered 6 comets. He knows his stuff & his forte is astrophotography. His pictures show that one fragment has brightened noticeably. This could be because it is getting ever closer to the Sun and as such continuing to become more ‘active’ — i.e., ‘evaporate’ giving out gases.

The comet has definitely fragmented. Of that there is no doubt or debate. The ‘orange’ Hubble picture shows 4-fragments and JPL (2nd image) already lists 5.

As the orbital diagram shows the ‘comet’ — or to be more precise — the fragments are still a longways out and we are moving away.

The fragments may be bright, but they are SMALL. So naked-eye visibility is questionable.

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.
