Hey folks, Christmas came just a little bit late this year...
http://dawnpub.igpp.ucla.edu QUOTE DAWN DATA RELEASE: LEVEL 1A DATA FROM APPROACH AND SURVEY It is a LOT of data. Just the Vesta Approach includes about 2000 FC images! Wow!!!The Dawn project has created a public website that is available to serve the cruise and Vesta data sets that have been delivered to the Planetary Data System (PDS) while the data are still under review. Data are available from all three Dawn instruments, the Framing Camera (FC), the Visual and Infrared Mapping Spectrometer (VIR), and the Gamma Ray and Neutron Detector (GRaND). The data that are currently available are raw data, in engineering units, sometimes referred to as EDRs by the PDS or as NASA level-1a data. Additional data sets will be added when they are submitted to the PDS. The Dawn website is located at: http://dawnpub.igpp.ucla.edu Users of these data should exercise caution. Invariably there will be errors or omissions in the documentation. Please report any problems... I think that the first thing I'm going to work on is that approach sequence/movie that I wish I'd had in real time. The rotation of Vesta through the image sequences makes color composition very hard, but I am sure there are people here who are up to it. I hope someone here can come up with a pretty color global shot that I can put into a comparison montage! -------------------- My website - My Patreon - @elakdawalla on Twitter - Please support unmannedspaceflight.com by donating here.

Just remember they're not to scale in Stefan's pic, machi.

I think that albedo is in scale.

The colors are fine, I know. I just mean the sizes in the picture are not correct; Emily made a montage that shows them right.

Thank you for that image! That will be useful for my next project. You are very welcome! A few words on the image. I made it because I was curious how these asteroids would appear to the eye. I tried to display them at their correct relative brightness, as you guessed correctly. We all know that there are many ways to approach "true color". This is my version; now that the data are public, anyone is free to make her or his own. |

Thank you all!
I must say, that this dataset is really gorgeous, with many tempting shots for further work. For joy (we have almost winter), I did one big snowman. It's mosaic from 36 images (3×12) in false colors. I used filters F4 (917 nm), F6 (829 nm) and F7 (653 nm). -------------------- |

That's amazing! Are those images from HAMO?

Yes, that's images from HAMO. I forgot that. I used images from 8368 to 8408 and from 12329 to 12369 (respectively F4, F6, F7 filtered images in those sequences).
Wyborowy!! You're welcome! BTW, I have no special knowledge of polish language, despite the fact, that I live few tens kilometers from Poland. -------------------- |

Machi, your mosaics of Rheasilva and Snowman craters are absolutely wonderful. Děkuji
