HAO Research Highlights

Gravity Wave
November 23, 2016

To investigate the Gravity Wave (GW) in the mid-latitude mesopause region during boreal equinox, 433 hours of continuous full diurnal cycle temperature measurements in September between 2011 and 2015.

properties of optical lightning flashes and the clouds they illuminate
November 18, 2016

Optical lightning sensors like the Optical Transient Detector and Lightning Imaging Sensor (LIS) measure total lightning across large swaths of the globe with high detection efficiency.

Schematic of the Sunrise Gondola
November 4, 2016

At one meter, the Sunrise Balloon-Borne Stratospheric Solar Observatory is the largest solar telescope to leave the earth. Its aim during its June 12 to June 17, 2013 flight was to study the magneto-convective processes of the sun at a resolution of better than 100 km.

Raw S082B image with wavelength scale
October 20, 2016

We study UV spectra obtained with the SO82-B slit spectrograph on board SKYLAB to estimate the fine structure splitting of the Cl-like 3p43d4D5/2 and 3p43d4D7/2 levels of Fe X.

Snapshots of poloidal field
October 10, 2016

The key elements of the Babcock-Leighton dynamos are the generation of poloidal field through decay and dispersal of tilted bipolar active regions and the generation of toroidal field through the observed differential rotation.
