Weather Satellite HRPT and LRPT Megaprojection Project Nov 30 – Dec 1
Over on the /r/amateursatellites subreddit, user elmarkodotorg is organizing a group megaprojection project. The Megaprojection Project seeks to create a composite of as much of the earth as possible from weather satellite images captured by hobbyists in a single day, via data from NOAA and Meteor polar-orbiting satellites. They will be accepting HRPT or LRPT data from either Nov 30 or Dec 1 (date yet to be confirmed).
Hobbyists can receive these satellites' LRPT and HRPT signals using an RTL-SDR and appropriate antenna setup.
If you want to contribute, you can join DerekSGC's Discord server, https://sgcderek.github.io, where coordination will be carried out. elmarkodotorg writes that currently, they have confirmed contributors with stations from the west coast of the US all the way over to the western edge of Asia. Currently, they are still hoping to find contributors from the Canary Islands, Turkey, Equatorial Africa, the general area of Indonesia, and Northern Australia. In a more recent Reddit thread, elmarkodotorg provides a link to a Google docs sheet, where you can also register interest.
Recently, on November 16 a test was carried out and they were able to successfully combine 24 images received across the world.
We did another one! Lost count of who is in this, but if you’re on Reddit, Discord, or the FB APT group then thank you once again for your work on 23/24th Nov. Unsure how long this link will last, but here is an 16,000 x 8,000 pixel version, 70 odd meg:

Hey guys! Thanks for writing about this. There’s probably more than 24 in there, we kept adding some and I lost count eventually at 46 or so after adding a few more areas. I ended up generating 4 versions of just this test projection. Sometimes we were using just a few hundred lines from a pass so it went right to the back. Often we’d layer HRPT passes over a longer LRPT pass, prioritising the quality. All blending was done in GIMP.
