HIRISE observations of daytime aurora over boston from ground in response to the magnetic disturbance of october 30, 2003 as corroborated by the TIMED measurements from space

HIRISE (High Resolution Imaging Spectrograph using Echelle grating) is a high-resolution spectrograph built at Boston University, which is capable of making unambiguous ground-based daytime airglow/aurora measurements. HIRISE has been making daytime red line (OI 630.0nm) emission measurements from Boston (42.2° N, 71° W) on all clear sky days since April 2003. On October 30, 2003, in response to a severe geomagnetic disturbance, HIRISE measured intense daytime red line emissions of 15 KR (scattered background continuum around 2 MRÅ^-1)^at 1500 LT (2000 UT; SZA around 75°), which are a factor of 6 -- 8 greater when compared to the typical quiet time dayglow emission rates at that time. Interplanetary magnetic field (IMF) B_z stayed negative throughout that day but showed a monotonic increase from --20 nT at 0 UT to --15 nT by 24 UT. IMF B_y was mostly positive (around 5 nT) throughout the day, which is known to move the precipitation/interaction region towards postnoon time, raising interest on whether the magnetospheric cusps moved as far down to mid-latitudes on this day. GUVI (Global UltraViolet Imager) onboard TIMED (Thermosphere, Ionosphere, and Mesosphere Energetics and Dynamics) satellite showed nearly an order of magnitude enhancements in irradiances of 1356 and LBH emissions during this time as compared to the quiet time values. Comparison against TIMED Doppler Interferometer (TIDI) brightness data will also be made. These different simultaneous measurements will be presented.
