Activity Level on the Sun

May 28, 2020

VERY LOW — No C-class flares in the past two days.


Today's Sun!

SIDC reports during last 24 hours, solar flaring activity somewhat increased, with a few low B-class flares reported. We expect a low level of flaring activity to persist with occasional B-class flares, C-class flares are possible but not probable.

Rather slow and faint CME was observed above the west solar limb early on May 26, its solar origin is not completely clear. However, if it was a front side event and its solar counterpart is a small eruption from close to the center of the solar disc, the CME-driven shock wave might arrive to the Earth in the morning of May 30. One more CME (first observed in the SOHO LASCO C2 field of view at 23:12 UT on May 27) was observed above the west solar limb. It solar source is presently not clear, more will be reported when more data will be available.

During last 24 hours proton flux levels were at background values and are expected to remain so.

Earth is still inside the slow solar wind with the speed of about 300 km/s. The interplanetary magnetic field magnitude is also low amounting about 4 nT. Small and patchy equatorial coronal hole (negative polarity) reached central meridian yesterday midday. The associated solar wind might arrive to the Earth late on May 30 or early on May 31.

Finally, SIDC reports geomagnetic conditions are quiet and we expect quiet to unsettled conditions in the coming hours.

Now . . . let's take a little tour into the realm of:
