    I can see some Cirrocumulus & Cirrocumulus undulatus above the Altocumulus undulatus clouds as well. Beautiful pic. :D

    This morning 6ish am SQ297 Singapore airlines came over the top Singapore to Christchurch NZ

    Melbourne only gets infrequent trails as few jets pass over at height required it drew some attention from local casual observers claiming meteor ufo on fire,, appeared to be falling etc.. i did my to best explain the trails origin and the optical phenomenon..

    oh it may have been EK448 Emirate to Auckland but that had passed 30 minutes prior and the trails had faded dispersed like SQ297 did within 20 minutes

    This "towards the ground" or "straight up" is one I keep encountering on cloud and weather pages on Facebook and it seems there's just no getting through to people once they've made their minds up. No matter how many people patiently explain it to them

    pleasingly i think i was able to show this was a plane the at 1st unsure thread author more or less accepted that it was

    same trail just a differing perspective without a rising sun & distance horizon its not appearing to go up or downwards

    Aged contrails over London this morning. I’m not sure why sometimes contrails turn into these “bobbly” clouds (cirrocumulus?) rather than the more usual wispy cirrus.

    Yesterday was a good contrail day in our parts:
    image-download.

    Turbulent skies over East Anglia gave fancy shapes to contrails and clouds:

    I think I managed to capture it on the GOES 17 imagery.

    Pretty sure the link in my previous post is supposed to be "real time" but it stopped updating on the 25th- could be related to the shutdown or it becoming operational??

    This one is also a few minutes old but has zoom too: https://www.ssec.wisc.edu/data/geo/#/animation?satellite=goes-17

    Holiday to Darwin City Australia.

    Began well with us on way to airport witnessing a day time meteorite was brief 2 plus seconds off amazing red yellow green mirror like I saw this appearing shook my head thinking it was a refection on car window.. Heading west on Bungower road mornington it was dropping straight down fast in the west sky colors it had no smoky tail or a sonic boom and we had no ability to tell where how high how far away.. Sadly :( we goofed & lost the dash cam footage by not getting the chip out soon enuff.. researching others observations analysis put it 250 clicks away from us.

    https://www.facebook.com/groups/Aus...549971362211003&notif_t=group_comment_mention

    Over head Darwin had a few trails,,, i was on holiday & had limited access to check RH and air traffic so this was 645am Darwin time looking east

    Here are a couple of shots I grabbed on my tablet becasuse it struck me how well they matched the kind of "revelation moments" view I have seen chemtrail believers report. I often see some contrails over my home, but this was an unusual and striking collection.

    The weather today is noticeably warmer and clearer than usual. I will leave further comments on the reason for such a fine display to others with more technical knowledge.

    Over Faversham, Kent, looking east at 13:37 pm GMT today

    The photo of contrails I used for my book was such a moment. I had just come out of a restaurant (in Cameron Park, California, Sept 17, 2017) after breakfast and saw this unusually good collection of contrails in the eastern sky. The rest of the sky was fairly clear, and it's quite rare to see this many. I think some kind of recollection bias leads people to think days like this are more common than they actually are.

    just an update on the meteor the boffins have been at work and calculated the meteor (Bolide) trajectory and landing place in or around Willaura Victoria. Bramon http://www.bramonmeteor.org/bramon/en/ a handy mob to keep an eye on for space junk rocks and sky observations

    http://www.bramonmeteor.org/bramon/en/video-analise-bolido-diurno-sobre-australia/

    i do like that my original landing site calculation by observation and computer skills i have learnt here

    was within 5 clicks of the 250 click away outcome i think thats in a MOA ( minute of angle )

    Good planespotting weather today (and the warmest February day on record in the UK, with the temperature breaking 20C for the first time ever in a winter month!).

    One short contrail, one long:

    upload_2019-2-25_15-14-12.


    In fact looking further to the left there was a third plane with an even shorter trail. All following a similar path, from the USA to Germany, but at three different altitudes:

    upload_2019-2-25_15-20-7.

    upload_2019-2-25_15-20-30.


    Despite the different lengths, none of the trails was persistent for more than a couple of minutes, thanks to some fairly dry air.

    This trail cast quite a dramatic shadow as it drifted in front of the sun yesterday afternoon. Also a faint sundog which I didn’t notice at the time (just above the chimney in the first pic, close to the lens flare dot).

    Especially awesome expanded contrails yesterday I just had to share. In one region of the sky, any contrail was expanding like this. Is this kind of streaking formation from a cloud (or contrail) called "fall streaks"?

    [​IMG]

    This is the continuation of the contrail above...

    [​IMG]

    This contrail fragment below, right next to the ones above, I shot as an example than contrails in a region of the sky (but not the whole visible sky) were being inducted into the same expansion mechanics, producing long angel-hair-like streaks...
