Observing 'GS 1826-238' (obsid 2739) with ACIS-S/HETG. Soft proton levels had decreased to under 1,000 but have been experiencing an erratic increase over the past 11 hours, in response to the M8/halo-CME event of 26 July. EPHIN values are low. 3-day Solar-Geophysical Forecast issued Jul 28 at 22:00 UTC Solar Activity Forecast: Solar activity is expected to be at moderate to high levels. M-class flares are likely from Regions 39 and 44. Either region could produce a major flare during the period. Region 50 could produce an isolated M-class flare during the period. Geophysical Activity Forecast: A geomagnetic field disturbance is expected to begin early on 29 July and continue into 30 July in response to the M8/halo-CME event of 26 July. Active to major storm levels are possible during this disturbance. Field activity is expected to decrease to quiet to unsettled levels on 31 July. Region 39 or 44 may produce a proton flare during the period. What's Up in Space -- 29 Jul 2002 NO IMPACT IN 2019: Headline-making asteroid 2002 NT7 will not strike Earth in 2019. "With the processing of a few more observations, we can now rule out any Earth impact possibilities for February 1, 2019," says Don Yeomans, the manager of NASA's Near-Earth Object Program at JPL. AURORA WATCH: Sunspot 39 unleashed an M8-class solar flare and hurled a coronal mass ejection (CME) into space late Friday (2110 UT). The CME was not squarely Earth-directed, but some of the expanding cloud is heading our way. Sky watchers should be alert for auroras when the cloud arrives--probably on Sunday night or Monday. SUNSPOTS GALORE: This weekend, the Boulder sunspot number soared to its highest value since March 2001. The largest of many spots peppering the Sun is sunspot 39. It stretches more than a dozen Earth-diameters from end to end, and poses a threat for X-class flares. You can see it yourself--but never stare directly at the Sun. Use safe solar projections methods instead.
