update: 1/20/20 - just happened to check website where original pre-live sighting image was captured, and found another glow along the same line-of-travel... from just last night, (hi time) but somewhat less mysterious-looking.  pictures #8,9 added at end. --- 1/1/20 - post-nye: while watching the below near webcam on 1/1/20 around/after 2:30 am pt (12:30 am ht -- since was looking for any final new year's fireworks) suddenly noticed a small seemingly submerged "oval-shaped" bright blue glow in bottom-right quadrant of view (in upper-half thereof, iirc) which over several minutes first moved slowly left, (paused a short time, iirc), then slowly back right and out of view, maybe more than once, (around 1 minute to cover same on-screen visual length as far breakwater, iirc -- est. about 700  feet out at roughly 0.8 mph,  via  running various sighting-lines on  google maps), leaving no wake though  normal white-shore-light illuminated wave crests  repeatedly passed by unaltered (not sure now  whether around  or over) --  then probably  fell asleep while trying to find more evidence or explanation.   some hours later found the  similar picture #1  recorded from a similar viewpoint (apparently the below far-view -- though witnessed  glow was somewhat lower than in  picture,  iirc, and thus closer to  camera). near-view: https://www.Streaminghawaii.Com/oahu-webcams/waikiki-beach-overview-webcam/initwbo far-view: similar  view from viewer  that says available 24 hours a day  but at night shows promo video instead -- but found out later the many live  camera views  can still be selected.   also,  alternate 24-hour viewer of same feed, and the  hourly/daily feed-snapshot viewer that captured the pre-live sighting. https://www.Marriotthawaii.Com/webcams/sheraton-waikiki/ https://www.Ozolio.Com/explore/hcou00000057 https://www.Webcamgalore.Com/webcam/usa/waikiki-beach-hawaii/10810.Html as the above links and pictures #1,2 show, there are  two different webcam views  covering somewhat the same area but  from different distances, one far at an apparent  1700ft (the captured sighting  found post-event) and one near at est 1000ft (for reference , the view where the live sighting occurred but was not captured;  nor was there any beam as in  picture #1)    if the maps here-below are  dragged, zoomed, scrolled, and 3d-rotated (best in that order) so that the url values closely match those shown, and each  map-window itself is resized  and positioned just right, then the results will approximate the near and far webcam  views, as  pictures #3,4 show.  the famous statue and its red balloon-clone set afloat  provide  zoom-persistent markers for the sighted object's approximate sea-position and line-of-travel, though the hula mound may be a more accurate reference if memory still  serves.    also, in the far view, the blue  balloon should roughly mark  the position of the object in the post-sighting-discovered pre-live sighting captured  picture #1.    note that the url values will  change as the map view is moved --  and most unfortunately they cannot  be set just by url;  nor with the place-search box,  as the balloon-clone will be lost.    note also that googlemap does not allow the virtual-viewpoint to be in  or on a building, and this will force  some  misalignment.    finally, since the far  webcam sends its 24h live feed  to  the website of a major hotel, and it is still less than a month since the sighting, perhaps the hotel server department just might  still have an offline backup left with some live video. near and far  webcam-view maps: https://www.Google.Com/maps/place/duke+paoa+kahanamoku+statue/@21.27.65408,-157.82.75237,81a,35y,141h,79.21t/data=!3m1!1e3!4m13!1m7!3m6!1s0x7c006df4e5c129af:0x4633ddc52a688878!2swaikiki,+hi+96815!3b1!8m2!3d21.2822932!4d-157.8310083!3m4!1s0x7c007276ebe11ae1:0x8c1b0bb567c94087!8m2!3d21.273655!4d-157.826819             https://www.Google.Com/maps/place/duke+paoa+kahanamoku+statue/@21.2769585,-157.8302029,112a,35y,133.87h,79.15t/data=!3m1!1e3!4m13!1m7!3m6!1s0x7c006df4e5c129af:0x4633ddc52a688878!2swaikiki,+hi+96815!3b1!8m2!3d21.2768491!4d-157.8304725!3m4!1s0x7c007276ebe11ae1:0x8c1b0bb567c94087!8m2!3d21.273655!4d-157.826819 initial summary  preserved asap, january 1 -- pictures #5,6,7: (originally also #1) while watching on  1/1/20 around/after 2:30 am pt  (12:30 am hi)  saw such a seemingly submerged blue glow move slowly left (towards  the beam  here [ref #1, now above] -- but there was no beam then), then slowly back right and out of view, maybe more than once, then maybe fell asleep -- before later seeking  and finding the below similar image, and assumed similar alternate view for reference  --  and now capturing them  here from  screenshots of still-open windows, as  they  just some minutes ago  ceased to exist. local knowledge: [see update above] asked each concierge/info-desk below about availability of local nighttime  undersea excursions.   none had any knowledge of such: https://atlantisadventures.Rezgo.Com/details/149523/atlantis-submarine-tour-waikiki/?_ga=2.181025767.1113184302.1578090480-2081372729.1577935896 https://www.Waikikibeachservices.Com/about-2/432-2/ https://www.Alohilaniresort.Com/contact-us/ https://www.Aquaaston.Com/hotels/aston-waikiki-circle-hotel https://www.Astonwaikikibeach.Com/contact/ https://www.Hyatt.Com/en-us/hotel/hawaii/hyatt-regency-waikiki-beach-resort-and-spa/hnlrw/area-attractions https://www.Marriott.Com/hotels/travel/hnlwi-moana-surfrider-a-westin-resort-and-spa-waikiki-beach/?Scid=bb1a189a-fec3-4d19-a255-54ba596febe2 https://www.Marriott.Com/hotels/travel/hnlws-sheraton-waikiki/?Scid=bb1a189a-fec3-4d19-a255-54ba596febe2 https://www.Outriggerwaikikihotel.Com/contact http://www.Honolulupd.Org/contact/index.Php -- also  waikiki station =end=
