Solar activity has been at moderate levels for the past 24 hours. The largest solar event of the period was a M2 event observed at 0850 UTC from Region 3697 (S18E07). The flare generated a Minor R1 radio blackout over Middle East region
The total number of sunspots has decreased to 186 of which 98 of them are grouped into 10 active regions as follows:
Active Region | Sunspots | Size (MH) & class |
AR3690 | 1 | 10 a |
AR3691 | 18 | 180 By |
AR3693 | 2 | 10 B |
AR3695 | 11 | 30 B |
AR3697 | 33 | 410 Byd |
AR3698 | 11 | 160 B |
AR3699 | 8 | 70 B |
AR3700 | 8 | 180 B |
AR3701 | 5 | 40 B |
AR3702 | 1 | 50 a |
The current magnetic field of AR3691 harbors energy for M-class flares while AR3697 continues with an unstable magnetic field beta-gamma-delta that harbors energy for X-class flares.
NOAA's forecast for the next 24 hours: 99% chance of C flares, 75% chance of M flares and 35% chance of X flares.

● Auroral Activity
The geomagnetic field has been at quiet levels for the past 24 hours. On June 01, Solar wind speed reached a peak of 351 km/s at 07:27 UTC. Total IMF reached 6 nT at 16:17 UTC.
● Current Conditions at 04:33 UTC on June 03
Aurora Oval Bz: -2.9 nT South
Geomagnetic activity is at Kp2 (quiet) The solar wind has a normal speed of 299 km/s pointing south with a negative Bz value of -2.9 nT which offers moderate conditions for aurora sightings at high latitudes. Thermosphere Climate Index (TCI) continues to be hot.
GEOMAGNETIC STORM WATCH (G1): NOAA forecasters say that a G1-class geomagnetic storm is possible on June 4th when a CME is expected to graze Earth's magnetic field. The CME was hurled into space on June 1st by a complex X1-M7 double solar flare. Much confusion has attended this forecast because there were actually two CMEs at the same time--one toward Earth and one away from Earth. Analysts unraveled the two storm clouds to produce a likely model of the Earth-directed CME's trajectory. SpaceWeather.com

Yesterday's asymmetrical full halo coronal mass ejection (CME) turns out to be a hard to catch curveball!
After a lot of discussion the general consensus is that the large asymmetrical halo coronal mass ejection likely came from an energetic far side event that occurred just before the X1/M7 flare combination. It is likely a far side CME and not earth-directed.
However, based on SDO imagery we do see some coronal dimming and a possible release of ejecta which was triggered by the M7 event. Did this eruption launch a coronal mass ejection? Possibly. Is it earth-directed? Hard to tell.
We turn to SEEDS where this SOHO/LASCO animation comes from. At the 20:24 UTC frame it starts to track what we believe is the M7 flare ejecta. It is so hard to tell due to the larger far side halo but it looks like this ejecta is slow and rather lackluster, perhaps not even earth-directed.
All in all, hard to say how much was released and its exact trajectory but we expect little to no impact at Earth unfortunately. Sunspot region 3697 is however in a prime earth-facing position right now so should it manage to produce an eruptive solar flare, any ejecta from it will likely have an earth-directed component.
On June 03 Solar activity is likely to be moderate while the geomagnetic field is expected to be quiet.
