“The projected turn-off date for FRB 121102 now is around August 31 – September 9, 2020,” if it stays on its previous repeating cycle.

August 26, 2020 Albuquerque, New Mexico – Two months ago on June 21, 2020, Earthfiles reported that at least one Fast Radio Burst known as 121102 FRB was reported by the U. K.’s Jodrell Bank Observatory as having a puzzling, repeating 157-day-cycle. Each radio burst from FRB 121102 lasted approximately 90 days, depicted by the turquoise energy lines pulsing from outer space to the Earth radio receiving dish.
Next was silence for 67 days. After the silence came more Fast Radio Bursts for 90 days. Then silence — on and on. No one knows how or why such enormous bursts of radio energy would be emitted in a precise, cyclic and repeating pattern. That cycle was not publicly reported until 2020. Out of 100 known FRBs, 121102 and one other are the only ones known to have a cycle of energy bursts so precise that the recent bursts from 121102 FRB were right on schedule for this month. On August 17, 2020, China’s National Astronomy Observatory detected twelve new radio bursts from FRB 121102. The repeating cyclic pattern is estimated to be 157 — or 156 — days. That means the FRB should end its active bursting phase between August 31 and September 9, 2020.
What Is Causing Precise, Cyclic Pattern of Fast Radio Burst 121102?
Scientists now want to see if there are any bursts from FRB 121102 beyond September 9th. If that happens, then either there is no true predictable, precise pattern — or the cycle has changed for reasons unknown. Scientists still do not know what the source of Fast Radio Bursts are. But the dwarf galaxy in which FRB 121102 has kept pulsing in a seemingly repeating pattern is at least 3 billion light-years from Earth.

The Astrophysical Journal Letters: “In an unexpected pay-off to follow-up investigations, additional Fast Radio Bursts were found from the same sky position as FRB 121102 with the same pulse dispersion measure, thereby unambiguously identifying FRB 121102 as a repeating source and demonstrating that the source of the bursts survives the release of energy required to produce them. Yet more bursts were found with both the Arecibo and Green Bank telescopes, but no obvious counterparts were detectable in X-ray, optical, or radio imaging observations of the field.”
Are FRBs A Bizarre Form of Magnetars?
On April 28, 2020, alarms were triggered at astronomical observatories around the world when a half-second powerful radio signal hit. That energy source was a neutron star on the other side of the Milky Way from Earth that died 30,000 years ago. In its death struggle, the star belched out a huge mixture of radio and x-ray energy. That fast-spinning, compact core of the dead star in the constellation Vulpecula is a known “magnetar,” that appears to have been the April 28th cause of the radio and x-ray belch. Magnetars are a type of neutron star believed to have an extremely powerful magnetic field.
So, the April 28, 2020, alarms signaled the first ever observational connection between magnetars and fast radio bursts,” said Sandro Mereghetti of the National Institute for Astrophysics in Milan, Italy. But will this magnetar “SGR 1935+2154” ever repeat on the same precise 156 or 157 day cycle as FRB 121102? If not, what is the difference between the known magnetar and the 100 Fast Radio Bursts recorded to date that include the cyclic pattern of FRB 121102?
