This is Volume 2 of the Ministry of Defence report 'Unidentified Aerial Phenomena in the UK Air Defence Region', Defence Intelligence Staff Scientific and Technical Memorandum 55/2/00, dated February 2000 and received 7 December 2000. It gathers 25 working papers on natural and man-made phenomena, meant as a reference for analysing UAP reports. The papers cover ball lightning, radar detection, balloons, satellites, mirages, plasma and similar subjects. One paper compares magnetic field experiments on human volunteers with close encounter reports. It concludes that effects from such fields are 'uncannily similar' to what witnesses describe.

# UNCLASSIFIED UK RESTRICTED UAP EFFECTS ON HUMANS, ELECTRICAL/ELECTRONIC EQUIPMENT AND OBJECTS ## SENSING THE PRESENCE OF A UAP 1. The ACCESS Database tables generated for the UAP study encompass all the sensing methods and descriptions, of which humans are capable, except touch. This paper provides an initial overview. Some of the topics are considered in further detail in following working papers. The sensing methods are: - Aided or unaided visual sight (including colours, shapes etc.) - Sound (Annex A) - Heat (Annex E) - Smell (Annex B) - Feeling (excluding actual touch), for example sensing air pressure, electrical fields (static effect on skin/hair, burning of skins) - Direct Thermal Effects (Annex D) - Taste (Annex C) - Description of the Sighting Location and Environment - Non-Ionising Electromagnetic Effects. (Annex F) 2. Animals Several of the effects are also found to extend, in some parameters, to other animals such as farm and domestic animals. 3. The following sections and subsequent working papers consider each of these effects briefly, as an aid to future analysis of UK sightings. The following review is not in any specific order of priority. Although it is very rare for the initial contact not to be by a visual sighting. The combination of more than one sensing effect, (at para. 1, above) is present on only some occasions. ## ELECTRO-MAGNETIC FIELD LEVELS 4. On the assumption that some sort of field emanates from a UAP, though not necessarily on all occasions, and is apparently only influential on humans when at close range; there are three field options, using the most familiar types of field to consider. These are: (a) Magnetic Fields A magnetic (H) field can be either natural (e.g. Earth's natural field), generated, or stored (permanent). Familiar magnetised ferrous-based materials form permanent magnetics, while solenoids generate fixed or varying magnetic fields. In the UAP context this would either mean the presence of large (and heavy) field generators on a substantial and solid 'craft', or a magnetic field being generated in a UAP comprised of, perhaps, a plasma. As is well-known a magnetic field is polarised, with lines of force (flux) travelling towards the opposite polarity either on the same source or towards the earth's surface. A magnetic flux can be modulated, although the rate and shape of the resulting energy time distribution is affected by the presence of inductance, capacitance and resistance. (b) Electric Fields Electric (Electrostatic) fields are set up between objects of opposite electrical potential. Familiar manifestations of the presence of an E field is hair standing on end/bristling For an E field to exist a non-conducting (free space, dielectric/gas) material must be between the charged entities. In the UAP context the E field, (for human effect) would conceptually pass between the UAP 'body' and earth, with the human in between. The human may be 'earthed' (i.e. standing on the surface), depending on the scenario.
