This eruption was initially strong in the sense that closed loops oscillated at the passage of a shock wave. But the eruption was more radial than lateral and the coronal wave was negligible. This event became the CME as seen in http://spaceweather.gmu.edu/seeds/mkmovie_ql.php?cme=20190422.032407.w036.v0318.p275&frame=8.

AR 12738 started showing eruptive behaviors only it approached the west limb. This eruption took place when the region's center of gravity was 10-15 degrees behind the limb. This one probably occurred in the northwestern part of the region, so it was more occulted. There was a decent CME (http://spaceweather.gmu.edu/seeds/mkmovie_ql.php?cme=20190421.050007.w078.v0251.p268&frame=19).

Like the previous two cases, the eruption was more lateral than radial. This one shows both the driver and front. Also note the clockwise rolling motions in the driver.

This looks homologous to the previous event around 20 April 2019 09:30. The propagating front is weaker. Instead, the driver is revealed in more detail, involving low-lying structures tumbling in the wake of the wave passing.

An eruption in AR 12738 mostly southward produced an EUV wave we had not seen for a while. The eruption was more strongly lateral (southward) than radial. The CME that resulted from the eruption was slow and weak (http://spaceweather.gmu.edu/seeds/mkmovie_ql.php?cme=20190420.100007.w016.v0269.p284&frame=7).

This may look similar to the previous examples of jets from the northwestern part of AR 12728, but this one was apparently on a larger scale since it was produced a CME (http://spaceweather.gmu.edu/seeds/mkmovie_ql.php?cme=20190420.012540.w065.v0314.p270&frame=12). Higher up, the eruption was deflected to south,

A small amount of coronal rain is visible from a small eruption near the umbra of AR12738.

The northwestern part og AR 12738 also abounded in narrow outflows. These may be jets but look also like blobs that may represent plasmoids.

The jet southward was seen multiple times from the western part of the big spot of AR 12738, probably reflecting long-lived coronal structures incluidng open field lines.
