Comitato Italiano per il Progetto Hessdalen Italian Committee for Project Hessdalen On the occasion of ten years of ICPH activity (2000-2009), Dr. Massimo Teodorani sent us a long "Letter to the Editor", that we publish as received. We thank the Author for this contribution to the open debate about instrumental methodology to be applied to the luminous phenomena in low atmosphere and for his special attention to Hessdalen-like phenomena. the editors SCIENTIFIC INQUIRY ON ANOMALOUS ATMOSPHERIC LIGHT PHENOMENA: PAST RESEARCH GAPS AND NEW METHODOLOGICAL GOALS Massimo Teodorani, Ph.D. Astrophysicist, Researcher and Science Writer E-Mail:
[email protected] ABSTRACT. On the basis of the experience of this author, a decade of scientific research on earthlights is amply discussed and pondered from the point of view of instrumental measurements. After an introduction that shows a brief synthesis of what has been done so far, all the different measurement techniques and tactical/strategic procedures that have been used so far or that are planned for the near future are discussed in detail. Constructive criticism on the gaps that emerged from this research is punctually pointed out. New procedural ideas are widely proposed and scientifically motivated in order to improve this research and to stimulate researchers on this field in order to search for an optimum common protocol. Keywords : astrophysics – criticism – data analysis - earthlight – electromagnetism – Hessdalen – instrumentation – methodology – measurement – physics – spectroscopy – strategy – tactics – theory – unidentified aerial phenomenon – VLF/ELF Introduction The recurrent behaviour of some anomalous atmospheric light phenomena such as “earthlights” (Il Laboratorio delle Anomalie, website; Long, 1990; Noguez, 2006; Odenwald, website; The Earth Anomalous Lightforms, website) has offered investigators an opportunity to study them scientifically.
