Hello to all - with heavy cirrus clouds moving in, I was able to shoot this
through the clouds during evening twilight....then the clouds came rolling
in for a couple of days it appears!
Note the pinkish tinge to oval BA and how it has grown in recent days,
particularly over the course of the past 10 days. Also note the string of
small white ovals/spots immediately following BA. There is much activity
surrounding the GRS as can be seen in this image, and likely due to current
interactions as BA is now nearly central in longitudinal placement to the
I expect a rapid change in motion for BA within only days, and am detecting
a slight acceleration of it over its previous rate at this time.
Beautiful rift forming very rapidly in the North Equatorial Belt....
this was taken in very poor conditions; shows the very prominent dark barge
B-4 very well. Note the nice irregularity in the south edge of the SEBs and
the darkening taking place south of the SEB on the approaching limb....
