Seeveral bright gold disc shaped objects seen through binoculars

Multiple bright gold orange disc objects were seen crystal clear through high powered binoculars this time. These objects were huge and glowing. Some looked like funnels or cones. One or two of these objects hovered in same basic hilltop area for 20 minutes while others appeared in multiple locations. The largest disc was seen on 11-18-19 at basically the same time 11 P.M. as these sightings. These disc or cone objects looked like the star like objects people are reporting until seen through binoculars they are flying discs seen as clear as day.

Multiple bright luminous objects seen mostly in groups of two hovering side by side over hillside tops. I had a witness step out onto the road to observe 2 brightly lit objects about a mile in front of us toward the south east horizon. One object was distinctly bluish white and the other object was golden yellow. My witness thought they were stars because of how they pulsated. A couple minutes later these objects were gone and multiple other objects continued to appear and hover.

I also believe I witnessed possibly the same sighting on 1-24-19 at 6:45 P.M from the Golden Gate Bridge toll Plaza as someone reported from Oakland. A huge yellow light was seen near the SF downtown skyline at exactly 6:45 to 6;50 P.M. No one else at the bus stop or tourists or anyone else seemed to be noticing this huge hovering light and a second object appeared briefly and then they just winked out like someone turning off a light switch.

Two huge plasma looking objects seen near Mt. Tamalpais.

Strange grouping of plasma fireball objects were observed interacting with each other in groups of 4 to 5. These were some of the most bizarre looking objects I've ever seen. One object to the left of this group was an oval bright yellowish orange. 2 objects appeared hovering side by side over the top of this Corte Madera hill for a solid 5 minutes. These two objects were every color of the color spectrum all blended together. These 2 objects were oblong and very tall and looked like the shape of a flower vase or wood burning stove with a curved section on the bottom. Several groups of these bizarre looking objects were seen in groups of 4 to 5 and sometimes in groups of 7 to 8 in loose formations. I estimate I saw 30 to 40 of these strange fireball objects on this evening. I saw these strange objects swarming through this Ross Valley area at two different times tonight at 9 to 9:30 and earlier in the evening roughly 6:30 to 7 o'clock.

Huge long luminous red cigar disc craft seen in Marin County.

I saw a huge glowing red disc-/cigar-shaped object manuevering back and forth in front of this hill on the east side of Corte Madera. This was a real craft and I saw it through high powered binoculars perfectly clear. It was a bright cherry red and completely lit up like a glowing light bulb. It had no lights on it, there was no haze around it and the whole craft was totally luminous.

I got an incredible look at it. even though I was about 3 or 4 miles away, I saw everything. It came from over the top of this hill and abruptly stopped near the right top of this hill. I specifically noticed that when this craft was moving it was a bright cherry red and when it slowed down and hovered, it changed to a dull orange brownish color. This craft dropped way down on this hillside almost landing on the grass and I could see the top of this object. It had some kind of a slanted curved dome like structure on the top and once again when it slowed down it turned a burnt ora! nge color. This object disappeared and re-appeared several times in various locations on the west side of this hill before it finally travelled from left to right and went in between 2 sets of hills at really low level and headed toward Mill Valley and Tiburon. I was looking down at this object from up in the hills toward the west and I could see it perfectly clear from the top and from the side through the binoculars. The night was perfectly clear and the size of this thing and the luminous glowing of this object was unbelievable.

I believe that other people might have also seen this as it was near the 101 Freeway and this incident happened at about 7:30 to 7:40 P.M., I wanted to mention that I had a "cluster of lights" sighting on 11-10-16 with 2 other witnesses. We saw a group of 8 to 15 orbs of light in San Rafael near the Bay. I am mentioning this because you have other San Rafael sighting being reported on 11-09 and 11-11-16 by independent witnesses.

Stationary yellow gold lights seen during extended long sighting

I watched a cluster of 2 to 7 yellow gold glowing lights stationary near the bay and Corte Madera marsh area. This activity went on for approximately 1 hour. Sometimes there would be a string of 4 to 6 objects in a row and other times there would be 2 bright objects side by side. This hour long activity would start to fade out and then start right up again.

Shiny objects over North Bay.

Witnessed multiple lights hovering near Corte Madera bayside hill. I first noticed it and then had a neighbor coming up the road view it with me. We watched these lights for about 10 minutes in eastern sky. We both came to an agreement that these were not airplanes. Seemed to be over the Bay .

Huge glowing red craft emerges from behind Corte Madera hillside.

I saw a huge red glowing object, shaped like a football with curved right and left sides, but way more circular and fat from top to bottom, literally rise straight up from behind a hill in Corte Madera, that sits on the Bay just east of Hwy. 101.

I have never seen anything quite like this in all my life. This craft rapidly approached a cluster of yellow gold luminous objects that I had been watching for the last couple of minutes. It started out as 2 or 3 lights, and then there were 5, and then 8, lights in a V-formation and in a straight line in front of this hill.

This glowing red object had no features except a sort of brim around the center, making it look like two inverted bowls held together and was strobing and pulsating in one color-a dark red. It was huge compared to these other yellow gold lights and looked very solid and metallic. It suddenly banked and headed to the south through San Francisco and kept going very fast.

Luminous red disc shaped craft seen on top of hillside

I was standing on a hilltop looking to the east with a pair of Bushnell binoculars when my eyes come upon a luminous red disc or football shaped craft against a hill in Corte Madera which is basically on the south side of the Corte Madera Marina where a series of hills overlook San Francisco Bay and these hills also include Tiburon-Mill Valley area to the southeast. This craft was huge and a dark red almost like a dark cherry red. It was totally lit up and glowing. I could'nt really see any details except it was basically disc shaped and maybe 100 feet long and not very tall. It looked like 2 plates joined together. This object looked totally different than anything else I've seen lately and it looked like it was sitting on the west side of this hill on the grass. During my 5 to 10 minutes I watched this object it moved from right to left about 200 yards really slow like at a walking pace. Then it just seemed to disappear like a light switch turning off. There were several other craft in the immediate area but they were really low key and barely visible unless you had binoculars. There was no sound heard except for the crickets outside. This is the second time in 9 days I believe I've seen a landed craft in this same spot and the other night on 9-12-14 I just happened to be filming with a camcorder and captured a craft that changed color from orange to white and basically moved from right to left about 200 yards on this hill. It could be that it was flying or hovering in front of the hill but even that is basically impossible for a normal aircraft. These craft (with the exception of the red disc) all look the same. They look like an ice cream cone turned sideways so the white light or orangish light is on the left and there is a black pointed tail shape to the right. They look like craft seen on Area 51 footage that I've seen in amateur footage. There were other white and orange lights that joined this craft that I have on f! ilm on 9-12-14 and a second craft looks like it's sitting on t! he right corner on the top of this hill.Anyway this hill in Corte Madera has these huge objects that approach from the east and hover over the left corner of this hill like a lit up Christmas tree and then they go backwards and down on the S.F. Bay side of the hill and then either the same object or another identical object will do the exact same thing and sink down behind the hill. If you are standing up in the hills you can really notice this activity and I wish more people would notice this. Any doubts I had that these might be conventional aircraft seen at a distance were laid to rest one night in April of this year when I was directly involved in one of the most bizarre close encounters-landing-other worldly encounter that was so unbelievable I still can't believe it.

Light object flashes then disappears over house.

While sitting out on our back deck, looking for the perseid meteor shower, my fiance and I witnessed something very strange. I am an amateur astronomer in my mid 40's. I have been looking at meteor showers and planets through several telescopes since I was a young girl growing up in the farming hillsides of northern england with my father. My fiance also - has been an amateur astronomer growing up in Montana. We are both fairly expert at seeing meteors and know what we are looking at in the night sky on most clear evenings.

We had seen several good meteors over a period of about 30 minutes prior to the strange light sighting. We were focused on the area around Perseus and Cassiopiea in the night sky. Looking directly west from where Cassiopeia is located at this time in our section of the hemisphere, and directly above my home - we saw a sudden and brilliant light. It was not a meteor. It didn't move from one point to another, there was no tailing off or t! rail. It was almost like a camera flash. It started off looking like a regular star in the night sky and the suddenly - flashed really bright - like a camera flash going off - on a much larger scale.

We both exclaimed as we saw it. My fiance explaimed "whoa did you see that" as I pointed directly up at it to show him. It flashed in a bright purple color. The strangest thing was however that as soon as the flash ended, the object which had previously been there - like a star - disappeared. It got stranger however when just a few seconds after disappearing, it flashed again but this time like an explosion - with this time a green light - and then also disappeared completely. We watch the night sky almost every night. The skies around the San Francisco bay area are crowded with planes. I know all the flight paths having lived here in this location for 18 years. And I know the many different colors and flashing signals emitted by planes. This was not one of them - bei! ng just literally a finger length from the area we were focuse! d on for the meteors, this was a star or so it seemed. I have not really ever paid attention to UFO stuff. But after telling my father about this strange light - he directed me to look at an online video of a UFO over Jerusalem which had descended to the temple hovered, and then flashed and took off. I wasn't going to write in to report this because I didn't think this was at all a showy or really eventful sighting and I have been thinking of all of the things it could have been. A military plane perhaps, or a meteor coming coincidentally right towards us on an angle where we couldn't see the tail -- but after seeing the Jerusalem video just now - the flash that that object emitted was almost exactly like the one I saw over my house. However the light disappeared after it flashed over my house - it didn't speed up into the sky as the one in the Jerusalem video did. I am a professional with a twenty year career in business as is my fiance. We are not and have never been really people! who believe in things we cannot prove with facts and science. Yet we both were really taken aback by what we saw and - having had years of studying the night sky - we have never seen anything like that and didn't feel like the flash disappearing then reappearing and the colors it emitted - were a natural occurrence. It wasnt a meteor. It wasnt a plane. I am not sure if this was a UFO but it defies explanation in my mind as to what could have behaved like that.

I saw a glowing, spherical object in the sky tonight that accelerated in speed, then disappeared.

I glanced up at the sky and, directly between the constellations of Ursa Major and Canes Venatici, was a fiery object. It moved west, horizontally for three or four seconds. The area it occupied began below Phecda (Ursa Major) and moved slightly past Canes Venatici. The shape was hard to describe. At first, I thought it was a plane. My neighborhood lies below a flight path so there is always a lot of air traffic, especially at night. I do, however, know the difference between a plane and something that is not. This object was about twice the size of an airplane and three times as bright. The shape seemed spherical, with a bright golden aura surrounding it. The center was the brightest, a deep gold/light orange. There was no trail or dust following it. The reason it caught my eye was because it accelerated in its speed. The best way to describe its disappearance was that it slipped into an invisible pocket in the sky. I am reporting this because I KNOW it was not an airplane and I was wondering if anyone else saw it. I really would like to know what it was. I see movement in the sky every night, but nothing ever like this and as bright as this.

witnessed approximately 1 second of flight of an object unknown to me in the northern hemisphere of the night sky.

this is the first time i have completed a report such as this, but i was curious as to what exactly it was that i saw. the objectwas triangular in shape and had a fuzzy white aura with a green core; it flew east in between the constellations of corona borealis, bootes, draco, and hercules. it then literally disappeared within 1 second; like it slipped into a pocket of invisibility. i was wondering if anyone there either observed the object or picked it up on their telescopes. i just happened to glance at the sky, myself. i wasn't even looking. anyways, i took two college level astronomy classes, i otherwise am always looking up at the sky. i really do not have much experience. but if someone could get back to me with an identification of the object, i would appreciate it. thanks!

stationary fireball changes color and redefines speed as it moves north

At first , it was just a high altitude stationary fireball. But three small dots emerged ( I'm assumming they might be Foo Fighters) and flew north. The fireball remained static until the dots(Foo Fighters?) returned. Then the high altitude stationary object turned from a fireball into an extremelly blue light and flew north at a speed that made the atmosphere burn in its wake.

When I say I have seen 4 crafts , it must be understood that I saw all crafts in one experience.
