Hallo Lutz,
STD hat zum Wohle der von doppelseitiger Polarlichtseuche dritten Grades befallenen Kundschaft einen ETA-Service aus der Taufe gehoben.
Die erste, d.h. inzwischen zweite Fassung hat's in sich.
Eine dritte würde mich nicht wundern ..., aber wir wollen ja erst noch wetten - oder ?

Subject: impact ETA
Very helpfull initiative, Cary !
Small Q: Impact time at Earth, is that at ACE, the first SSC or the time the magnetometers start to react. (There can be 1 to 2 hours between the first and the last)
(And if you have time for a larger Q: how do I visualize the position angle in "LASCO-derived Plane of Sky Velocity: 338 km/sec at position angle 268 degrees.". Why do you mention it, c.q. what does it tell us bout possible aurora ? )
Max.

Subject: NEW CME IMPACT ASSESSMENT SERVICE
HEAR YE, HEAR YE...
Commencing immediately, STD will begin providing estimated time of arrival impact assessments for most coronal mass ejections that
may have an Earthward directed component at the web site:
http://www.spacew.com/cme
We urge everyone to use caution. As I've said on numerous previous occasions, these predictions are often based on uncertain,
assumption-laiden quantitative values and may therefore often be inaccurate.
The service will include brief summaries of the source event, estimated impact windows, preferred impact times, estimated predicted
shock impact strengths, and a prediction indicating which direction the Interplanetary Magnetic Field (IMF) will turn immediately
following the impact of the shock. Please note that this last prediction does not necessarily define the direction the IMF will maintain if
the Earth intersects a magnetic cloud type feature. It only defines the anticipated direction of the IMF as a direct result of field draping
around the shock front.
This is an experimental service. Whether we commit to providing this service will depend in large measure on how well it is used and
whether we can justify taking the time to maintain it.
Estimated shock impact times will probably not be made on this forum in the future. I may interject estimated impact times in here now
and then, but my time is very limited. Instead, I would appreciate it if all of you would help keep those in this forum informed by posting a
note whenever you notice the
http://www.spacew.com/cme web page is updated. I'll have an extra link to the page also added as
part of the Forum home page.
We hope that this new service will be of some value to all of you.
THE LATEST CME IMPACT ASSESSMENT for the full halo CME of 01/02 November is now on-line.
