Figure 1

BP detections by the STEREO and SDO spacecraft taken around 00:00 ut on 2 February 2011 when the entire solar corona could first be seen by all three spacecraft. The top row (ac) shows coronal images from a plasma formed around 1.5 MK. The small bright concentrations seen in these images are BPs. The bottom row (df) shows the same images with respective BP detections15 shown in red (STEREO-Behind), white (SDO) and blue (STEREO-Ahead).
