:Product: Weekly Highlights and Forecasts :Issued: 2001 May 08 2112 UT Highlights of Solar and Geomagnetic Activity 30 April - 06 May 2001 Solar activity ranged from low to moderate levels. Region 9433 (N17, L = 153, class/area Fki/1070 on 25 April), which had been in a process of gradual decay since producing a major flare on 26 April, crossed the west limb on 01 May. It produced isolated low-level M-class flares during 01 - 02 May as it crossed the west limb (see the Energetic Events list for flare specifics). This region was also responsible for multiple CME events observed from beyond the west limb during 02 - 03 May. Activity decreased to low levels on 03 May with isolated C-class subflares, mostly from Regions 9445 (N25, L = 027, class/area Fai/390 on 01 May) and 9447 (N12, L = 061, class/area Eai/260 on 04 May), both of which were moderate-sized with a slight degree of magnetic complexity. These regions were gradually decaying at the close of the period. Data were available from the Advanced Composition Explorer (ACE) spacecraft for most of the period. No significant disturbances were observed in the solar wind flow during the period. There were no proton events during the period. The greater than 2 MeV electron flux at geosynchronous orbit was at normal levels. Geomagnetic field activity was at quiet to unsettled levels. Forecast of Solar and Geomagnetic Activity 09 May - 04 June 2001 Solar activity is expected to range from low to moderate levels during the period. Isolated M-class flares will be possible during the period. No proton events are expected during the period. The greater than 2 MeV electron flux at geosynchronous orbit is expected to be at normal to moderate levels during most of the period. The geomagnetic field is expected to be at quiet to unsettled levels during the period (barring an Earth-directed CME). .
