The resources and asteroid observing expertise of MIT, the University of Hawaii, and the NASA IRTF are being combined in a joint campaign to perform routine spectroscopic reconnaissance of near-Earth objects (NEOs). All spectroscopic observations obtained in this joint campaign are being made publicly available in near-real time via this website.
Acknowledging Unpublished Data from the Joint Campaign
Spectra presented here are considered to be in the public domain and may be freely used for any purpose. We welcome collaboration opportunities, but there is no pre-condition for collaboration for use of these data. Researchers utilizing these data without collaboration arrangements with the observers are asked to include the following acknowledgement in their publication(s):
"All (or part) of the data utilized in this publication were obtained and made available by the MITHNEOS MIT-Hawaii Near-Earth Object Spectroscopic Survey. The IRTF is operated by the University of Hawaii under contract 80HQTR19D0030 with the National Aeronautics and Space Administration. The MIT component of this work is supported by NASA grant 80NSSC18K0849."
We further note the following disclaimer:
"Any opinions, findings, and conclusions or recommendations expressed in this material are those of the author(s) and do not necessarily reflect the views of NASA or the National Science Foundation."
Also note the following request from the IRTF website:
Observers publishing results obtained with SpeX are requested to reference the following paper:
Rayner, J. T., Toomey, D. W., Onaka, P. M., Denault, A. J., Stahlberger, W. E., Vacca, W. D., Cushing, M. C., and Wang, S. (2003). "SpeX: A Medium-Resolution 0.8-5.5 micron Spectrograph and Imager for the NASA Infrared Telescope Facility." PASP 115, 362.
Important Caveat: All users must take into account that these data are unpublished and therefore have not undergone peer review. While it is our intention that these released data are fully reduced into their final form, until such time they are accepted for publication, it is possible that reprocessing or recalibration could be deemed necessary. Any such reprocessing or recalibration will be noted as updates to this web site.
Joint Campaign Observations
We present 0.8 to 2.5 micron wavelength spectra measured using the instrument "SpeX" on the NASA Infrared Telescope Facility (IRTF) on Mauna Kea, Hawaii. When available, visible wavelength spectral data are also included from the MIT SMASS observing program. The description of the data files documents data format, rejection, and normalization.
(New!) Observational Circumstances for MITHNEOS Data
We are now providing observational circumstances for the MITHNEOS dataset to make it more accessible and useful to the community. Information such as start time, airmass, total exposure time and more are provided in the MITHNEOS Observational Circumstances document (Last updated Mar 2022). A description of each of the columns is provided in this readme file.
(Also new!) Change log
A few asteroid spectra were recently re-uploaded to the website following the identification of errors in the MITHNEOS database and other data-related notes. This document (Last updated Nov 2021) describes the list of changes made after the original public release of the spectra. We strongly encourage the community to re-download the most recent version of the spectra listed in the document.
