MEGS-B “Flare” Campaign to support Incoherent Scatter Radar at Arecibo

February 8, 2012
The Arecibo Observatory

The Arecibo radar is the largest single dish radio telescope in the world. Its main use is the research in atmospheric science, astronomy and planetary science. Image courtesy of Ana G. Mendez University System, Student Research Development Center, NSF, NASA, NAIC, SRI International, and UMET.

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.
