HiWind was the first balloon borne Fabry-Perot interferometer designed to measure summer time polar cap thermospheric neutral winds. Thermospheric wind measurements are critically needed for space weather research. HiWind was launched June 14, 2011 from Kiruna, Sweden.

Fabry Perot Interferometer at Resolute Bay, Canada

Resolute, Canada (75N) is the site chosen for the deployment of the National Science Foundation Advance Modular Incoherent Scatter Radar (AMISR). AMISR is a state of the art phase array radar, which allows fast electronic steering of the radar beam to track fast moving auroral features.

Fabry-Perot Interferometer at Palmer, Antarctica

The Palmer station Fabry-Perot interferometer project is funded by the National Science Foundation Office of Polar Programs. The goal is to study the upper atmosphere and ionosphere over the Antarctica Peninsula. Palmer station is an year-around US Antarctica Research station located on the Anvers Island near the Antarctica Peninsula.

Fabry-Perot Interferometer at Boulder, Colorado

On March 16, 2012, a Fabry-Perot Interferometer (FPI) was installed at the NCAR Marshall field site, just to the south-east of Boulder, to observe thermospheric and mesospheric winds.

Dr. Philip Judge, convened the HAO Solar-Stellar Workshop on March 19-20 at the High Altitude Observatory of NCAR in Boulder.

Mk4-STEREO-LASCO Composites

HAO / MLSO is now providing daily composite images of the solar corona as seen from 3 viewing angles: STEREO B, Earth-Sun, and STEREO-A. The STEREO A/B composites consist of SECCHI images from: EUVI (inner corona seen against the solar disk), the MLSO MK4 K-Coronameter (blue), the COR1 Coronagraph (green) and the COR2 Coronagraph (in red). The SOHO/MK4 composite combines EIT (solar disk), MK4 (blue) and LASCO C2 (red). MK4 images are NOT rotated to match the STEREO viewing angles.

Full Res Mk4 Images & Movies Available

The home page of this MLSO website now features full-resolution GIF images and movies for the Mk4 instrument. Clicking on the thumbnail images for this instrument will now give you higher resolution GIF images of the latest data.
