In 2013, Newell upgraded the OVATION Prime design to make sure that it would far more properly seize large geomagnetic storms. The initial product, based mostly exclusively on DMSP details, was only reputable to Kp of seven. By introducing facts from the NASA TIMED GUVI instrument, Newell et al., had been ready to develop the design to incorporate the larger storm values of Kp of 8 and 9.
