DESCRIPTION UNCLASSIFIED 1 Between 0320 CST an<t 1130 CST on 31 Hay 1953, eleven persona in the Dnrling- ton~onroe area ln Wioconain sichted nn unidentified aerial obJect. The obJect appeared na a etead7 white ligbt coming eenerall;y ou~ or the East and disappear- ins htch overhead after 0 hours ot continuoua obeervatlon. It appeared lov on the Eastern horison, Jll!lCb briehter than the surrounding stare. It waa reported to hqver ond then move at terrific apeede b7 several local 1nhabi tante, includ .ins aeveral count7 eheritte and Oround'Obeerver Corp membera. !Vo or the police- Mn pureue4 the obJect in their equad car without pinins an7 noticeable ground. A teieecope vae em;plo1'!4 to view the bJ the COC meabere. The veathezo during the ttme ot eichtinJ WBa unusually clear with a tew acattered clouds carried on a north heading bJ the wind. II. DISCUSSION A newspaper account ot.the sichting came to the attention ot AT!C and as a result an officer and an astronomer vere sent to the area ot the eight1ng. The7 interrosated eight or the eleven obaervera in attempting to piece together the variet7 ot reports. Eatimates or azimuth and elevation reading were obtained from different observers at varied locations in Monroe and Darlington tor evenly spaced time intervale during the 8 hour period. The description or the . obJect turned out to be the same vith all observer -bright white. 'l'be dea- criptiqn ot the neneuvera varied, however, oome stating the obJect rose slowly, others aa)'ias 1 t moved at sreat speeds, and then hovered. 'l'he latter description uauall;y come troa obaernre vbile riding in a car. All agreed that the obJect vas too bript to be a a tar and moreover it vaa seen in the 4ayt1me. It vaa 4eteradne4 that the path ot the obJect in queatlon acrose the sky, ita poeitlon at appearance and disappearance, very closely paralleled the path ot the planet Venus on 31 I.Jay 1953. Venus on tbia day rose at 0310 CST and vas at ita approximate max1ww brilliancJ. Under ideal weather conditione it can be seen in the 4ayt , although this is rare. 'l'he tact that OOC personnel tirat sighted it at nigbt and bad the obJect pin-pointed tor da7light obaervation.al- lowed tbeJI to keep it under constant surveillaace. Reports that the object man~ euftl"ed radically usual17 came from persona driving in care vhlle observing the obJect. It Venua is stared at tor any length ot time without 8D7 balancing ref- erence point 1 t caD appear to erratic maneuver. GOC personnel alerted the Chicago tiltezo center and Jeta vere scrambled to inveetigate. 'l'hie vaa 4urlq da;yligbt obaervatiOD an4 the Jete, although vec- tored tovarcl the obJect b7 Yisual directions troaa Darl~gton '!ere mable to loeate the unlmowo. UNCLASSIFIED S..
