08 Aug 2021 - Every 20 Years / Thermonuclear Explosion On Rs Oph In Ophiuchus

• 
  "August 9, 2021: Every 20 years or so,
  a thermonuclear explosion occurs on the surface of RS Oph,
  a white dwarf in the constellation Ophiuchus.
  
  Yesterday, it happened again.
  
  On Aug. 8th, the brightness of the tiny star increased 600-fold,
  from magnitude +12 to +5.
  
  Keith Geary of Ireland was the first to notice."
  
  --- Interesting is that RS Oph is at 27,46 SAG
  is closely aligned with the Galactic Center at 27,09 SAG,
  sharing the same zodiacal longitude.
  
  This is another indication of an increased energetic influx from galactic origin.
