Observing '4U1755-33' (obsid 4586) with ACIS-S. Solar proton levels are low. 3-day Solar-Geophysical Forecast issued Jun 24 at 22:00 UTC Solar Activity Forecast: Solar activity is expected to be low. Region 635 is expected to produce C-class flares, and isolated M-class flares are possible. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet to unsettled for all three days (25-27 June), with periods of isolated active and minor storm conditions on day three (27 June) as Earth comes under the influence of a high speed solar wind stream from a coronal hole.
