Magnetopause crossings during the 2019 dayside constellation

The two figures below show the relative timings of the Cluster spacecraft as they cross the magnetopause during the 2019 dayside constellation (November 2018 to July 2019) - the first figure shows inbound crossings whilst the second shows outbound crossings. The solid lines indicate the crossing times of the four spacecraft using the standard colour scheme: black for C1, red for C2, green for C3 and magenta for C4. All times are relative to the C1 crossing time, with positive times indicating a cross occurring before the C1 crossing time.
