CR 2234 Summary
By Kim Hay
Acting Assistant Coordinator
Carrington Rotation CR2234 started on 2020-08-11 1150 UT and ended on 2020-09-07 1745 UT.
On July 26th sunspot AR2270 rotated onto the Sun in the northeast and remained on the Sun until August 14th. This group produced a C2 class solar flare from the decaying sunspot.
On August 12th sunspot AR2771, which was in the southern hemisphere group of Solar Cycle 25 regions showing on NASA’s magnetic map, was visually seen on August 13th but gone by August 15th.
August 16th the Sun produced a B1 class flare in the southern hemisphere but no spots were evident.
Sunspot AR2772 showed up August 18th in the northern hemisphere producing a CME that missed Earth on Aug 20th as per NASA’s STEREO A satellite.
On August 28th the Sun produced a minor G1 class geomagnetic storm that produced Arctic auroras with solar winds of 500 km/s hitting the Earth’s atmosphere. Auroras were observed again on August 31st for five straight days.
The Sun then remained blank to the end of CR2234, reflecting very low activity with our Sun still waffling between Cycle 24 and 25.
