SUMMARY: Linear MCS South of LMA Makes Sprites

TLE PREDICTION: 0.36 (0.9x0.4)

RESULTS: 16, debris clouds block view but some distant sprites seen

LESSONS: Sprites started after character of cloud top changed

PERSONNEL: Nelson, Fossum, Nordem, Gerken

STEPS STATUS: STEPS over.

YRFS OPERATION LOGS: Upslope flow caused widespread storms along Front Range which blocked viewing until long after. Full moon also a problem. Monitored to southeast were large MCS evolved from a squall-line like systems in southeast CO and Kansas. Many sprites blocked by clouds but some seen over top of fog bank. Sprites moved around so getting telescope fix was tough.

STEPS OPERATIONS: STEPS over
