Observing 'LALA CETUS FIELD/LAL' (obsid 4129) with ACIS-I. Solar radiation is currently low (under 100). 3-day Solar-Geophysical Forecast issued Jun 12 at 22:00 UTC Solar Activity Forecast: Solar activity is expected to be moderate to high. Regions 375 and 380 remain capable of producing major flare activity. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet to unsettled through day three, with possible active conditions on day two due to elevated solar wind speeds as a coronal hole passes into geoeffective position. Active conditions on day two might also be the result of potential effects of CMEs related to major flare and erupting filament activity observed on 11 June 03.

In this case the current may stay down. - ACA temperature dropped another degree to -13C, decreased dark current substantially. SOT(Bill): - See above notes on radiation. DSOPS(Joy) - Two quick looks today. GOT/IST(George): - ONline system version 3.9.3 was approved for promotion in yesterday's FDB. - Work on upgrade of EHS workstations will start next week, will entail some downtime for EHS stations. - Everyone should move critical data off of EHS home directories as they will go away.
