Going to jinx it, ISS transit of sun later this week

Recommended Posts

Everything seems too perfect for now. There's an ISS transit of the sun on late Wednesday morning, visible not too far away from me. Two weather forecasts currently suggest it'll be clear skies then.

What could go wrong? Well, the weather forecast is for almost 2 days away so there's plenty of time for it to be wrong. Also, I haven't managed to ask my boss yet if I can take an early lunch to catch it...

I need to plan where I want to see it from, the ground track passes through the Cotswold water park and there's various car parks in there I could try. Since I will be imaging from a car park, I can take more kit than I did for the Venus transit previously, and will go with both Ha and white light kit.

So rig 1 will be PST capturing continuous video.

Rig 2 will be DSLR with solar filter... but I'm not so confident in getting the timing just right for this one as it's only 0.8 second window!

Coo, this sounds like I should try to join in the fun :) I'll have to check to see if it will actually cross the sun for me, then work out which scope to use. Somehow I think the Mak might be too demanding.

Aha! CalSky claims that I do get a solar transit on Thursday afternoon. Typically however, whilst Wednesday and Friday are forecast to be sunny all day, the forecast for Thursday is only "sunny intervals". The transit will only last 0.84 seconds though. Surely even our weather could manage an interval that long at the right time?

Dear me. Can't be going there. They're a funny lot up Minehead way...


Fussy So 'n' So , if you draw a straight line from Alcombe to Northcott Mouth that's the centre-line of the shadow pass , 3 1/2 Km either side will get you a shot , but the further off the line then the further from the centre of the disc the ISS will be.

The Monday one is actually far better in terms of length of transit for me but I just can't do anything there, so if Thursday doesn't come off then I shall have to wait.

What could go wrong???? now where do i start.

1. it will probably rain here in the UK

2. there is a chance it will rain here in the UK

3. it may be wet here in the UK

4. Cloud may roll in and ruin the view

i love the british summertime, its so predictable, :grin:

Hope the weather holds out it will be amazing to see, hope you pst the shots when you have them.

Got it! Was touch and go due to cloud, but it thinned enough at the moment. Unfortunately it was a few seconds earlier than predicted so I was looking at the clock and not the screen at the exact time, but found it in the video afterwards. I'll process it when I get home tonight before I can post any images.

      My name is Luiza, I am a student of Computer Engineering in São Paulo, Brazil and I would like to ask for your help.
      As yesterday was the super pink moon day, I, at about 22:50, decided to take several photos of the moon using my phone and my non-digital telescope. And, analyzing the photos now, I realized that in some of them there are certain objects that I can't say exactly what they are. Could you help me identify them, please? I am not sure if they are satellites, ISS, Hubble, etc ... and I am very intrigued by themphotos.rar.
      P.S: the objects are in the lower left corner of the images

      I'm posting in the hope it helps anyone else considering a Daystar Scout SS60. The video's not quite representative of what one sees looking through the scope, but gives a general idea of field of view through a 24mm EP.  When observing, much more prominence detail and surface texture is visible to the eye and the colour feels less red than it appears in the vid.
      I'd have taken this video sooner if I'd realised that afocal video would work so well, so I'll try again next time the sun's available earlier in the day during better seeing. The video's taken by holding an iPhone against an Explore Scientific 24mm eyepiece and adjusting exposure (i.e. afocal video photography). Although I find a Plossl as easy (if not easier) to use as a wide EP for observing, it's simpler to align a smartphone with an eyepiece that has a wider field of view, for afocal video. Hence I used a 24mm ExSc (see below for detail). It seems a fairly quiet solar day, not long after the notoriously quiet 2020 and I believe is still close to the beginning of the sun's new 11 year cycle (hopefully it will become more exciting soon but not as exciting as having any Carrington Events pointing towards us).
      I spent some hours, from late morning, watching these prominences form, dissipate and reform. The prom on the Western limb was very tall and bright, looking like a large rectangular tower block, which gradually split, faded as the top looped over to the north, then the top looped back again to the south. At one point this loop appeared to join - forming the outline of the head of a man, whose figure, with arms out, was clear and rather funny. Wish I'd taken this video sooner (or had the ASI183 to hand). The prom quietened and reached its current state (3pm ish) as seen in the video.
      The long group of prominences to the South - 4 main and some smaller - were more dim than the prom on the Western limb initially, but they remained impressive, ranging from good to very small and appeared at one point to be as clear row of pine trees, especially the larger right hand prom, with spiky 'branches' and a distinctive triangular fir tree shape, which gradually brightened then faded to this view. The tip of the ‘sharks fin’ to the left of the group extended out to the east then receded.
      I'm afraid it's not easy to see the detail in such a simple video - it's slighly more visible to the naked eye. By the time I took this video it had gone 3pm, there was more haze and a lower sun and none of the prominences were particularly impressive.
      There were No sunspots easily visible, although a Plage appeared to be visible close to the Westerly limb. Little surface detail other than orange peel, despite tuning the scope (better with the SS60s dial to left of centre for this today). I still need to lots more time with the scope to get the best from it.
      I'm a Ha beginner having only observed in whitelight before and only having used this scope twice before, once in combination with a ZWO ASI 183MC astrophotography video camera. Medium seeing, 6/3/21 'third light' on the Daystar Scout SS60 Scope with fixed chromasphere quark built in - 930mm f15 60mm.
      Various Eye pieces used: Plossl 40mm, Meade Super Plossl 26mm, Explore Scientific 24mm and 11mm 82 and 68 degree EPs gave good clarity and contrast, but the seeing's not good enough for close viewing of proms.  ioptron motor, roughly pointed north was perfectly sufficiently good to keep the sun in view for at least 45 mins at a time. I'll edit this post to add a pic or two of the equipment setup in a moment.
      3 images attached are: Afocal Smartphone still image (contrast increased in smartphont), plus two shots of the setup.
