    I am seriously one lucky son of a…

    This is my second capture of a plane transit across the sun. My first one was captured with a white light filter on a CST but this time I captured one with my Coronado PST. I had the gain cranked up to gauge what prominences were on show. So no details on the chronosphere ( I am trying to suppress my natural urge to say surface! ) so just prominences. This was actually taken on 13th but I didn’t know I caught it until now! Thing is, I take so many videos, I don’t actually have my eyes on the laptop all the time, so I missed it live. I dont even play all my videos, I just click them at random….this now teaches me to now click through all of them! Who knows what else could be caught, Peter Pan, Tinkerbell, a flying teacup.

    So this is using my new QHY5L-II…strange how the sensor dirt dont show up on this one, (is it because of the high gain, Rupert?)

    Anyway, without any further irritatation of my rambling, may I present my plane transit video

    …I er…like how the plane creates two massive prominences on its exit, what a plane πŸ˜‰

    PS Could I possibly be the first one to capture a plane transit with prominences? I have scoured the internet for others but none shows prominences…just wondering!

    That is just ridiculous! Seriously, well done!!

    I suspect you are right as regards the sensor dirt. The disc of the Sun is overexposed, so the light is probably bleeding through the areas affected by dust.

    This deserves a wider audience, I think. Do you mind if I link to the video via our Twitter account?

    Sure Mike. I never used twitter, although I have an account which is bizarrely active due to auto running apps I am using. But I never tweet because I don’t know how to compress my long ramblings! By the time I start getting to a point, my character limit would be reached.

    Where was I? Oh yeah, sure Mike I’m honoured for you to tweet my vid.

    I was also wondering why am I lucky with these transits and I figure its because I mostly observe the sun when it’s around 40deg above horizon in the east or in the west and that I might be on a frequent skylane path. There is a really cool website with an accompanying iPhone app that gives live tracking views of planes if anyone wants to deliberately try capture plane transits with their lunar and solar imaging.

    That is a fantastic video, Tej! Wow! As soon as I see it in my Twitter feed i’ll retweet it!

    Flightradar24 is one of my favourite apps, though I can imagine it’s still difficult to know whether you’re in <i>exactly</i> the right position to capture another plane like that.

    My guess is you’ve caught a large business jet probably on the downwind leg of the circuit for London City Airport. It would have turned right then right again to land on the eastward runway. Biz jets and many of the other planes going into LCY usually don’t have the kind of electronic gear that can be detected by FlightRadar24, so don’t be surprised if you see planes in the sky but not in the app. Almost everything that goes into Heathrow, however, does have that equipment and in Peckham, like in Forest Hill, you’re almost certainly close to the flightpath for LHR’s (west) runways 27 Left and 27 Right.

    Just such a great video, though. So cool!

    Wow, Andy that was like a Sherlock Holmes piece of elementary deduction, forget my video, THAT was cool!

    You’re right, I did see/hear planes overhead not on the map. I guess you’re right also in that it would be hard to plan an imaging transit with that but at least can get a gist of where the more frequent flights paths are.

    I suppose its probably much easier to plan an ISS transit given its more precise orbital path available on web and mobile platforms.
