Transits of Objects through the LASCO C3 and C2, and STEREO/SECCHI COR-2A and HI-1A fields of view (FOV), in 2020


The following list was compiled by Worachate Boonplod.
All dates and magnitudes are approximate.Note that the limiting magnitude for LASCO C3 is approximately 8.0 to 8.5 (depending on object/star), and for C2 is approximately 8.5 - 9.0.



This image only shows transits across the LASCO field of view. We do not currently provide a graphical representation of the SECCHI transits. IMAGE CREDIT: Worachate Boonplod
