| Solar Activity |

| .24 hr Summary... |
| Solar activity reached high levels. Region 3663 (N26W12, |
| Ekc/beta-gamma-delta) produced an M9.1/1b flare (R2/Moderate) at 04/0619 |
| UTC, the strongest of the period. A Type II (est. 950 km/s) and Type IV |
| radio sweep along with a Tenflare were observed with the event. A CME is |
| suspected to be associated with the flare but additional coronagraph |
| imagery is need for conformation and analysis. This region and Region |
| 3664 (S19E32, Ekc/beta-delta) continued to be most complex. Region 3666 |
| (N07E10, Dai/beta-gamma-delta) also exhibited notable growth. |
| Other eruptive activity included a C3.9 flare at 03/2037 UTC from an |
| unspotted area to the east of Region 3666 (N07E09, |
| Dai/beta-gamma-delta). This event also produced a Type II (est. 392 |
| km/s) and Type IV radio sweep. An associated CME, first seen in |
| SOHO/LASCO C3 imagery at 03/2218 UTC, was analyzed and modeled. The |
| results suggested the slow-moving periphery should pass by Earth around |
| 09 May. |
| --- |
| .Forecast... |
| Solar activity is expected to be at moderate levels |
| (R1-R2/Minor-Moderate), with a chance for X-class flares (R3/Strong or |
| greater), over 04-06 May. |
| --- |
| Energetic Particle |
| --- |
| .24 hr Summary... |
| The greater than 2 MeV electron flux was at normal to moderate levels |
| and the greater than 10 MeV proton flux was steady at background levels. |
| --- |
| .Forecast... |
| The greater than 2 MeV electron flux is expected to continue at normal |
| to moderate levels over 04-06 May. There is a slight chance for the |
| greater than 10 MeV proton flux to reach S1 (Minor) storm levels over |
| 04-06 May due to the flare potential of Regions 3663 and 3664. |
| --- |
| Solar Wind |
| --- |
| .24 hr Summary... |
| The solar wind parameters returned to nominal levels over the past 24 |
| hours. Total magnetic field strength was at or below 5 nT. Solar wind |
| speeds declined from the low 400s to near 370/km/s by the periods end. |
| Phi angle transitioned from negative to positive polarity after 03/1830 |
| UTC. |
| --- |
| .Forecast... |
| Mildly enhanced solar wind conditions and positive polarity CH HSS |
| influences are likely to prevail over 04-06 May. A stronger |
| disturbance is expected late on 05 May and 06 May due to the anticipated |
| arrival of the 03 May CME associated with the X1.6 flare from Region |
| 3663. |
| --- |
| Geospace |
| --- |
| .24 hr Summary... |
| The geomagnetic field was quiet. |
| --- |
| .Forecast... |
| The geomagnetic field may reach unsettled and active levels on 04 May |
| due to positive polarity CH HSS influences. Active conditions and |
| periods of G1 (Minor) storming are likely on 05 May due to continued |
| positive polarity CH HSS influences in addition to the anticipated |
| arrival of the 03 May CME late in the day. Periods of G1-G2 |
| (Minor-Moderate) storming are likely on 06 May due to continued CME |
| activity and CH HSS influences. |
