Recovering an asteroid only in one frame / where $ when were the images taken

  • std.nrd by std.nrd

    I found a really bright and fast moving asteroid but its only in one frame. So, it could be recovered if I can loo for it, but I dont know where/when the image was taken.

    1. is there any way to discover the coordinates of these images and when they were taken?
    2. Are images posted in real time or in batches? I mean, are they months old or days old?

    PS, how many arcseconds are the images from side to side? Seems like a better search strategy would be to cover the same section of sky every night. Eventually an asterodi is going to wander through the field of view. As long as you are in the plane of the asterodi belt, more or less, it does not really matter WHERE you point the telescope, you should have an equal chance of spotting something wherever you point it, so why not image the same region of the sky every night.

    This discussion talked about about arcseconds, plus a link to a site for identifying coordinates, though I have not used it:
    http://talk.asteroidzoo.org/#/boards/BAZ0000003/discussions/DAZ00002a3

    And there is some more discussion on the displaying of the location of images in this thread (on the second page):

    From what I understand the images we are looking at are in batches because the survey that the images are from started in the 1990 and is continuing today.

    OK, wow, http://nova.astrometry.net is AMAZING. How do they do that?

    So I found an asteroid in this image:

    And I post a link to the image on http://nova.astrometry.net, and in a few minutes I have an annotated link that shows me exactly where in the sky the image was taken, and even annotates some stars (the bright one is Tycho-2 277-656-1)

    About the time, there seems to be a date in the file name, could that be the date when the image was captured?

    01_12APR18_N04062_0001-49

    Is part of the filename a timestamp? Possibly 4:06 AM UTC?
