abstract = "Discrete increase in plasma electron density by a factor of two or
more was observed in the F region of the nocturnal ionosphere in
the Brazilian sector, in the Manaus-AM region (MAN; 2,59°S;
60,22°O; dip. latitude 12,1°N; region near the magnetic equator).
This increase was observed through the imaging photometer data and
measured by the DMSP F15 satellite. Plasma density irregularities
in the nighttime equatorial ionosphere were first observed by
Booker and Wells in 1938, when they discovered spread-F in the
ionogram of backscattered signals of ionosonde in Huancayo, Peru.
The increase in plasma electron density was reported for the first
time by Oya et al. in 1986, and they named this irregularity as
plasma blobs. The plasma blobs that we observed on the MAN region
were events that occurred independently, that is, without the
presence of plasma bubbles. Cases of independent plasma blobs are
rare events to observe, with more frequent occurrence with the
simultaneous presence of plasma bubbles. In this work we present
results of 4 nights of occurrence of independent plasma blobs in
the period from October to November 2015, calculations of zonal
and latitudinal drift of these blobs, besides measuring the north/
south and east / west dimensions that they reached, during all the
time they were visible on the lens of the imaging photometer.",
