Their spiky anisotropic radiation is oriented w.r.t. the Galactic disk via interstellar accretion, whose orbital angular momentum tends to counteralign with the Galactic spin; in this way, larger source numbers in directions of the Galactic disk are compensated by smaller beaming probabilities, resulting in a near‐isotropic arrival distribution, as observed by BATSE. The source distances range between 10 pc and 500 pc. Their radiated energies are of order 1035 erg, corresponding to accreted clumps (blades) of typical mass 1015 g per burst. Magnetic surface field strengths range between 1010 G and 1013 G, perhaps somewhat weaker than those of newborn neutron stars. In this communication, we explain why we are still convinced that the soft repeaters have distances ≲50 pc, and how our model can be updated to incorporate the recently observed hard tails (E≲10 GeV for t≲102 s).

The class of supernova remnants thus splits into (i)(the usual) 'shell remnants' and (ii)'pulsar nebulae' in which a (fairly young) pulsar blows its relativistic wind into its low-density environs.

Thunderstorm overall voltages fEdz are (only) of order MV, slightly above fairweather voltages, insucient to charge the`geocapacitor'. Instead of charging the ionosphere (via Wilson currents), thunderstorms occasionally discharge towards it, with emitted spectra ranging from the visible up to gamma-ray energies. Fairweather charging takes place, so we claim, via the negative drizzle of the`heavy' aerosols, of radii between 0.1 mm and 0.1 mm in the troposphere.

These re-ejections can only be achieved by nuclear-burning of the strongly compressed hydrogen inside their central accretion disks. SMBHs cannot do it.
