Super bright white flashing bright then dim kinda sparkling- but NOT a planet- not a meteor or aircraft.

Seen from east facing window. Clear night sky- almost due east- about 45-50 degrees above horizon based on tree line and my line of sight. No wind, no objects obscuring my view. Have no idea of height or distance from me- don’t know size - have reference - couldn’t make out a shape. Stationery large bright white light with long sharp twinkle rays - no rainbow coloring in rays- bright then dim no noticeable timing pattern. It did not move. Then seemingly randomly 3 times went completely dark for less than 1 second. Don’t know if there was any sound as I was inside the house. I’ve seen planets, shooting stars, satellites and meteor showers- it wasn’t any of those. I’m also a skydiver and this was not a helicopter or any aircraft I’m familiar with- nor was it a blimp- or military aircraft- as I’ve seen in many times in So Cal. I grabbed my phone and headed out back door to get video- took me about 7 seconds- looked easterly and it was gone. Waited several minutes, scanned sky, nothing. Sorry I couldn’t video it. I hope others saw n report it. It was stunningly breathtaking- and I’m not easily impressed.
