SDO/HMI continuum and magnetogram images show an

active region spot  ~8 arcsec in size with several pores forming

at location N18W22 on 18 August 2020 at 0627UT.

SDO/HMI continuum image update at 1023 UT showing two

spots separated by 35 arcsec.  The original image has been

blown up by a factor of two.  This active region is changing

rapidly.

Top image is of the photosphere using a SW80 scope, Baader red ccd-IR

filter, an unpowered Quark, tilter, and ZWO 290 mono.  Bottom image is

of the chromosphere using the same equipment with the Quark powered up.

Top image taken at 1405 UT and bottom image taken at 1420 UT.  Plate

scales are the same in both images.
