They are still high but the GOES HRC proxies started to drop overnight and they are now beteen 40,000 and 70,000 depending on the proxy. The ACE P3 rates are elevated at around 3,000, which is safe for ACIS, so either the expected CME has not arrived yet or the impact was weaker than the forecast. Solar activity is expected to be moderate with a 25% chance for X-class flares on days one, two, and three (13 Feb, 14 Feb, 15 Feb). MP: No issues. ENG: No issues. GOT: No issues.
