Though we expect the Sun to be rather quiet today, we will be running a MEGS-B campaign in support of special incoherent scatter radar measurements being made at Arecibo. The campaign will run from 13:50 UT Feb 8 to 01:15 UT Feb 9 (essentially daylight hours at Arecibo). This will establish a “quiet” Sun baseline for possible future ionospheric campaigns.
UPDATE: MEGS-B successfully measured the sun. Unfortunately, there were transmitter problems at Arecibo and no ISR data was taken during the campaign. The Sun was not as quiet as anticipated since the active region vanishing on the west limb produced several B-class flares and one C2.9, and second. Also, a new region of emerging flux appeared in the south east quadrant.
