I went out for my once daily exercise walk in the evening,just caught the end of sunset.We are only allowed one lot of exercise a day currently in the uk as we are on lockdown due to covid-19 sadly.Due to being a key worker,it is often evening before i manage to escape! i watched the remnants of sunset,it was beautiful.I was walking along the beach which is very close to my house & it was still light but going towards dusk.I took quite a few photos along the way as i always try to...It is my hobby.I was walking along towards kingston gorse & ferring on the greensward right next to the beach.After a few minutes walking i realised it was very near to dark i spun round facing the way i had come & saw that in the far distance a part of the sky still had a rosy hugh & decided too take a couple of shots of it.Where i was standing next to the sea it was quite dark,as it was a very cloudy night.There was a very large bank of cloud directly above me & stretching out over the sea,so i could not make out much of the sky...But i thought it would make a great contrast in my photo,next to the clear rosy bit of sky in the distance.Anyway i continued on my walk as far as ferring & then decided to turn back towards home.It was very dark by now & i switched on my torch as it is totally unlit along there & i felt a bit spooky,eerie.I hurried home after that but it is quite a distance to walk.When i got home i took the memory card from my canon camera & put it into my laptop to look at the photos.I was flicking through them & then noticed that one looked a bit odd compared to the others...Right on top of the large bank of dark cloud were three perfect white spheres.They were quite well spaced apart & in the shape of a triangle.Sometimes when i look at it ,it appears to be an iscosceles triangle,but sometimes i think it resembles a right angled triangle.I have been racking my brain trying to come up with an explanation for this,there were no lights anywhere in the vicinity to cause a reflection & nothing for any light to bounce off of.There may well be a logical explanation but i don`t know what it is.I had a slightly similar experience late last summer at a different location & with a totally different camera.Which i sent into mufon...Simply because i have had a couple of very close up sightings of craft in the sky very low down in the sky twice in my life & a decade apart.I am not a nutcase or on drugs or drink!! i just seem to get these odd experiences from time to time in my life.The strange thing that night was that i was feeling very anxious about the covid-19 situation & the lockdown in the uk.We are not allowed to visit anyone,family or friends,because of this when i went for my walk i said out loud"beam me up scotty! take me away from this disease ridden planet!"...There was no-one there to hear me or i would not have said it! therefor when i saw this photo with the spheres i was pretty amazed & laughed out loud! anyway i have no idea what has caused them to appear on the photo & it is really the shape that they make,that made me stop & wonder about it.To me they almost look like they could be lights on the corners of some craft or plane.Though not any planes i am aware of,we do not really have much if any flying going on in the uk currently,there are hardly any light aircraft & even fewer large jet aircraft due to the situation that is ongoing.I am interested to know what you think about this photo anyway.Many thanks for your time.
