Capturing the partial solar eclipse of June 2021

I live in the UK and I’m an amateur astronomer, I’m very familiar with the vagaries of the weather and how a run of seemingly perfect days (nights) before an astronomical event will come to a crashing halt with a sky of clouds scant hours before the event starts.

With this in mind, and after a run of days with perfect blues skies, I’d decided to not make a great effort to view the eclipse; instead I just took a small, cheap spotting ‘scope to work with the intention of using it to project an image of the sun if the sun ever became visible.

Ten minutes before maximum eclipse there was no sun to be seen, not even a dim disc though the clouds, just a diffuse glow. Undaunted, I set the telescope up on a crap tripod I had laying around the lab and got it roughly pointed at the sun. I improvised a sunshield around the objective lens with a bit of cardboard box. The projection screen was some copier paper suck to a Tea-tray.

The sky cleared several times around maximum eclipse and I managed to snap a few photos and do a bit of impromptu science communication with people wondering what I was doing.

Lockdown update

Nothing much to report – the log of the days fell by the wayside quickly as nothing much was changing and the days blurred together before I could note them – making notes on them was my attempt to impose some un-blurring on the whole time so it all got a bit self-referential and pointless.

I’m never going to be a diarist.

We’re now a month into the CCFS course I teach on, remote learning technology woes aside, the course is going pretty well. It is looking like we may never meet the students face to face – some students are finding this hard to accept.

One evening’s astrophotography occurred in January, it was mostly beset by equipment issues but I did get one reasonable image.

M42 – The great Orion Nebula. 120 second exposure at 700mm focal length.

Lockdown 3, Week 1

I didn’t document lockdown two, as it really didn’t seem to change things much. Work happened as normal, my cycling dropped off somewhat due to the weather and other issues, and I started using the tube again to get to the lab. The District Line heading west was mostly empty unless you hit particular times; even at its most busy, it was nowhere near pre-pandemic usage. Masks seemed to be in use by most people, often just skimming or sitting below the nose. Those determined to make a point of not wearing a mask were as blatant about it as possible. Groups of teenage males seemed to be the most likely to ignore mask and social distancing requirements.

First day back at work. Walked from home to Stratford (9 miles or so) then caught the bus to Mile End. An easy enough walk, but not one I’m likely to do too frequently. I followed the usual route I’d cycle.
The day was mostly meetings about teaching and getting things up and running the in the lab. Rumours we may be about to go into Lockdown 3 started at lunchtime, two of the PhD students expressed concerns about how this would impact experiments and their progression. Unfortunately, it’s all up in the air.
I left early enough to get and empty train home.
We’re in Lockdown 3, but don’t call it that. No word from the university regarding the lockdown, I’m going to assume it’s a repeat of Lockdown 1 until told otherwise.

Cycled to work. The bike needs some attention, still making some odd noises.
Still so word from the university, I shut down the lab again and head home.

Wednesday 6th January 2021
Woking from home today, it’s online student induction all day; I may as well do this from the comfort of home with all the Tea I can drink on hand.
Before the induction kicks off, I receive an email from the university that boils down to “Business as usual”. I find out from a follow up email that I’m an

Induction goes well, it’s a good group of students this year. It’s a shame we may never meet any of them face to face.
I spend the evening watching a bunch of cunts attack the US Capitol. I miss the final eviction of the terrorists because I’m asleep.

 Thursday 7th January 2021
Again working from home. Pretty sure I was supposed to be attending a virtual conference today, I got the day wrong – it’s tomorrow. Spent the later afternoon – evening adding new data to the conference presentation, and generally catching up with a colleague over zoom.

Friday 8th January 2021
Awoke to a hard frost, which had just started to clear when we got an unexpected flurry of snow. The snow laid for an hour or so on the still frosty patches, but melted almost instantly everywhere else. The dog does not like snow.
The actual conference day. Again, working from home. Fixed a few snags in the conference presentation, then had the first tutorial session with my tutor class.
Presentation went well, we should turn the results into a journal article soon. Attended a colleague’s professorial inaugural lecture on zoom, congratulations to them.

Saturday 9th January 2021
Took the dog to the park, much muddier than I expected. I took a few photographs, mostly of trees, these were the best ones:

This tree was almost perfectly monochrome against the grey sky, it only took a little bit of desaturation to bring it out.

A clear night is predicted, so I set up the telescope for the first time this year, aiming to try out NINA for control and imaging instead of APT that I usually use.
Lit the woodstove in the shed to keep warm while I worked. I thought I’d use some smokeless cure I picked up last year. Useless bloody stuff, it took forever to light and burned so slowly the shed never got above 8 Celsius.
Neighbours had a house party in defiance (or ignorance) of tier 4 restrictions.
I managed to get an hour of imaging on the andromeda galaxy and had started to get to grips with NINA when all the imaging went to crap. Upon inspection, the heater band on the telescope objective was not able to deal with the extra cold snap we had and the lens started to fog over. I packed away, and will need to improve the heater before next time.

Sunday 10th January 2021
Walked to the shops to but some supplies for the week. Ended up buying two bags of compressed sawdust logs for the woodstove, I’ve used these before and they throw out loads of heat. Getting the shed up to 25 celcius when it’s freezing outside is not unusual.

Back to the lab.

I’ve spent twenty weeks away from the lab, one and a half of those with a creeping infection trying to eat my right arm off at the elbow and a further four of those some form of holiday (except for the four days spent working over those four weeks).

I’ve taken to cycling to work, which takes me down the A13 to Beckton, and then on to the Greenway to Stratford. I’m really rather pleased by the cycle routes available now, definitely improved since I last used to cycle that way about twenty years ago. I’ve only nearly been hit by a white van once.

Cycling to work obviously presents me with a chance to gather data, so data gathering I’ve been doing. I’m using google fit and runkeeper on my phone to log the journey and they both agree it takes between 45 and 50 minutes door to door. I’ve have a better idea when I’ve collected more than a week of riding.  The same journey on the Tube would take 45 minutes on a good day and closer to an hour typically. The one thing I’m really missing is the time to read on the train – it’s hard to multitask on a bike.

Only a single Astrophoto worth sharing this week. Five hours integrated exposure on NGC6888  – The Crescent Nebula. This is a work in progress project.

It’s what happens when a star sheds a load of gas into the surrounding neighbourhood, then sometime later starts blasting out a ferocious stellar wind, which catches up with the earlier shed gas and ploughs into it with enough energy to make it glow in visible light and X-rays.

Quarantine – Week seventeen (Holiday week 1) + eighteen (Holiday week 2) + nineteen (Holiday week 3)

Oh, yeah. Writing.

I spent the first three days of week 17 (holiday week 1) virtually present at the Bone Research Society meeting. I had a couple of other meetings that week too. So much for being on holiday. The dog did get plenty of walks and treats and will probably miss me greatly when I do return to work.

Holiday week two was much more of a holiday (from work, at least). No meetings attended, no emails replied to. I should do this more often. I explored Valence Park with the dog and found he is well behaved off the lead and quite happy to come when called and generally tear around the grass like a mad thing. It goes without saying that I only do this when there is no one else around or no other dogs close by.

On Saturday of week two, I cycled from home to Regent’s Park via the London Library to meet with some friends for a socially distanced picnic. Cycle route provision in London is so much better than I remember from 15-20 years ago. After a few hours in the park, my legs were cramping up on the cycle north. The bike is now awaiting the attention of a service engineer before I start using for my regular commute.

I did a bit of comet chasing this week, including taking my camera and tripod over to the park at 11pm for a darker sky and a better view North. I was undisturbed aside from a couple of mosquitoes, and a tiny blue light in the grass that turned out to be a dog being walked at distance.

Holiday week three has flown by, more dog walking and one evening’s astrophotography.

The Ring Nebula and surrounding stars

The sky conditions look poor for the next week or so, so that’s probably the last imaging I’ll get to do before I return to work. Fingers crossed to hear more from the job application in progress.
