European Space Weather Week
ESTEC
November 18, 2005
SEC Joins National Weather Service (NWS) as one of the official National Centers for Environmental Prediction (NCEP).
09 Sep 2005: NWS Director, D.L. Johnson, briefed space weather conditions to NOAA Chief of Staff (Scott Rayder), who in turn briefed the General Counsel (Stan Sokul) of the Office of Science and Technology Policy in the White House.
Space Weather is now included in the daily and weekly NWS reports to NOAA and DOC leadership
Space Weather UpdateNOAA sunspot group 808 stayed very active this week and produced several significant solar flares (up to R3 on the NOAA Scale). The strong (S3) radiation storm that started Sep 8 ended on Sep 11. Moderate to strong (up to G3) geomagnetic storm conditions were observed from Sep 12-15. During this period, aurora was visible as far south as Colorado and Lajes Field, Azores, Portugal.

Space Weather Program constraint #1
– Regional space weather forecasts and the transition of models and related research into operations
The need- Customers operating on continental and sub-continental scales are demanding regional specification and forecasts of space weather.
The Response - NASA, NSF, and DOD have expended tens of millions of dollars to develop models of the local and regional reaction of the space environment to forcing inputs from the Sun; many of these models are now mature and ready for transition to operations.
The Problem - NOAA’s Space Environment Center (SEC) has been unable to fund transitions of these critical models. Lack of resources constrains NOAA’s ability to deliver what customers want.
Status of NOAA’s efforts to get an operational solar wind monitor
So how do we convince the decision makers?

Status of NOAA’s efforts to get an operational coronagraph
PPBES - It is proposed to fly a coronal mass ejection imager (CMEI) on GOES-R series.
Coronagraph imagery is expected from NASA’s SOHO and STEREO satellites until about 2011. Then, CME images will cease, as NASA has no plans to fly a replacement coronagraph.

This need has been accepted as valid by the GOES-R project, as reflected in the GOES Mission Requirements Document (MRD) and Program Requirements Document (PRD).
However, the CMEI has been deemed unaffordable by the GOES-R project. It is not manifested for flight on GOES-R, although it is listed as a high priority Pre Planned Product Improvement (P3I) if additional money becomes available.
The January 20, 2005 Radiation Storm, once again, caused impacts:
“Its been nasty …. The S3 (NOAA Scale) two days ago resulted in less optimum polar routings to Polar 4 rather than Polar 3, and lower flight levels. All this increases fuel requirements and reduced revenue payload. In addition, because of the effect on HF comms, we have abandoned polar today altogether. We must stop our Chicago to Hong Kong in Anchorage because no other routes provide non-stop capability.”
G. Cameron, Dispatcher, United Air Lines
United Airlines identified space weather as the #1 concern during polar operations
The September 2005 space weather also caused considerable impacts:
The New York Comm Center reported:
07Sep 1800Z: Solar activity severely impacted all HFcomms. Higher frequencies utilized with little effect. 24 aircraft position reports and NYC ATC messages were relayed via sat-voice between 1040Z and 1939Z. Severe operational impact.
The San Francisco/SFO Comm Center reported:
07Sep 1755Z: SFO sends ARINC Solar Flare Activity Advisory of moderate to severe impact to HF comms to airline customers. SFO experiencing extreme HF "white-out“ conditions virtually wiping out all Pacific HF.
11Sep 0050Z: Tokyo and Port Moresby Radio having difficulties, SFO will assist as needed. 13Sep 1930Z: Solar activity severely disrupting HF comms in all Pacific areas throughout daylight hours. Severe communication impact and severe operational/service impact.
Major airlines rerouted flights away from the poles because of current and anticipated space weather conditions. This occurred several times during the September activity. These costly reroutes (~$100k) require an additional fuel stop and new crew.
The advent of new long range aircraft such as the A340-500/600, B777-300ER and B777-200LR
On June 18, 2004, the US and China concluded a bilateral air services agreement, permitting a nearly 5 fold increase in weekly frequencies over the next 6 years.
Airlines operating China-US routes go from 4 to 9 Number of weekly flights from 54 to 249 over the next 6 years.
The Transportation Dept estimates the economic impact of the agreement at $12 billion in additional revenues for US carriers over seven years. - IATA
