Re: Arecibo Telescope to close.

Hard to imagine the scale of this receiver. According to the article links from SpaceWeather.com the main instrument platform, which fell, weighed 900 tons. That’s a lot of weight to support.

Best wishes, Jeff.

Re: Twilight days ...

It was very refreshing to wake up to this morning. I saw the Moon heading over to set, and it looked fabulous. I like to take a few moments to just stand and watch on mornings like these, and appreciate the beauty of the view. How lucky we are to be able to witness such scenes.

Best wishes, Jeff.

Re: Jupiter-Saturn conjunction

I think from my current location I may just get away (weather permitting) with viewing the conjunction on the 21st, and leading up to it. I have a gap in between houses where I think they will fall just right. The screenshot shown below (taken from Stellarium) is for 4:30pm on the 21st, with the pai...

Re: The STEVE phenomenon

Yes, it’s easy to see why STEVE might be confused with auroral displays. I love the description of the purple glow being caused by “hot (3000 degrees C) rivers of gas flowing through the Earth’s magnetosphere faster than 13,000 miles per hour”. It’s quite mind boggling to try and imagine. Best wishe...

Re: The STEVE phenomenon

This is really fascinating. The pictures are incredible. It must be a really beautiful thing to witness - especially the green pillars.

Re: Mars Opposition in a 90mm Refractor

This is a super piece of work, Bob. I think I’d have this mounted and popped on my wall if I’d produced it.

I’m equally impressed that you’ve been able to flatten out from a series of sketches. Well done indeed!

All of this detail with a 90mm too. Thanks for posting it here.

Best wishes, Jeff.

Re: Arecibo Telescope to close.

I’m only just catching up with the news about this. How very sad.

I heard Vicky Duncalf mention it during Friday evening’s SPA Popastro Live broadcast (which have been great to watch) via Facebook.

Re: Jupiter-Saturn conjunction

I’m looking forward to this too.

Funnily enough, Nigel, we’re in the middle of moving house, and my observing opportunities have been severely curtailed. Good luck with your move.

Best wishes, Jeff.

Re: Another "Sunspot" - 19th November

Cliff, it’s great to see your white light image of this particular sunspot. I haven’t observed the sun telescopically for a long time.

Come to think of it, November seems to have been especially grim weather wise, and I haven’t even seen much of it at all.

Best wishes, Jeff.

Comet Erasmus (C/2020 S3)

According to SpaceWeather.com, comet Erasmus has brightened to 7th magnitude as it approaches the sun, and is an “easy” telescopic target. They have some links to finder charts on their page.

Best wishes, Jeff.

Re: An astronomical coincidence

Mike, that’s a fabulous coincidence. How lovely to see a photo in the book from the same date as your first view.

Re: Uranus in a small telescope

Very interesting, Bob. I like your setup - it looks fairly portable and easy to use. As much as I love observing, I find my enthusiasm for lugging my 8” Dobsonian out of the garage and into the garden wanes quite easily. I’ve never been successful in rendering colour in a sketch, other than an attem...

Re: Visually entailed comets

Interesting list, Mike. There’s a few on there I didn’t get to spot. Didn’t get to see McNaught - am I right in thinking there was only a small window of observation for northern hemisphere observers? I can’t recall Ison or Utsumomiya. I’ll have to dig back through my notes and check. Some memorable...

Excellent. Good to know it will be going to a good home. I’ll pop it in the post to you tomorrow, Mike.
