Strange red and blue pulsating lights (crafts?) to the S / SE of Cupertino? 12/5/17 @ 10pm

Last night (12/5/17) at around 10pm, I noticed a strange light in the sky to the south/ southeast of my home. It was much too bright to be a star as you could see stars up above where this object was and the contrast between the stars and this object was very obvious. It was definitely not a plane either as this object would hover then make jolted type movements. At one point I watched this object completely disappear gradually, and about 45 seconds later reappeared closer to my home. It had a pulsating light that would change from red to blue, then to white but with no distinct pattern. I couldn’t figure out what this thing was and I started to get a bit nervous. Living near the San Jose airport, I’m fairly good at spotting the objects, even in the night sky, but for the life of me I couldn’t figure out what this thing was. If it had been a helicopter we would have easily heard it and would have recognized the flight patterns. At about 10:20pm this object was! still hovering in the night sky, only moving once in a while, and very quickly. I called for my mother-in-law to come to outside so I could get another perspective on what this object was. Immediately my mother-in-law was also convinced this was much to close to be a star, as the pulsating red and blue lights were fairly obvious. That’s when my mother-in-law noticed there was a second object as well. It was further away than the one I had been watching but as we watched this other object it too looked as if it was making similar movements and color changes, and coming closer to our home. I even pulled up a star chart on my phone and this object was appearing on the star view camera but not registering as a star, nor was it close enough to any star that it would be mistaken as such. Normally if it’s a satellite, this star map app will tell you. I tried to take photos and videos but my phone’s camera isn’t the best quality. I just want to know what this thing was, and if anyone else in the Cupertino / San Jose area also witnessed this object?

((ADDENDUM FROM WITNESS))

Mr Davenport,
Thanks for your response. I’m sorry to bother you guys, but yes I believe you’re right that it was Sirius. I guess I just never realized how bright it can be at times! I must have stared a bit too long as well because I could swear it was moving. I’ve since read that that can happen if you’re focusing on an object too long in the night sky? The night I saw it, it wasn’t registering on the star map app I was using, but I know those apps can be faulty on exact gps locations because last night when I looked, it did register as Sirius. Thanks again for your response!
