This software has been well over a year in development. With this software you can: - Determine whether aurorae might be observed from your location. - Determine the potential magnitude of auroral activity. - See whether HF radio signal paths cross into the auroral zone where significant signal degradation occurs. - Superimpose any number of great circle paths on the maps. - Determine the best azimuth for radio transmissions to avoid the instabilities of the auroral zone. - Graphically draw the position of both the northern and southern auroral ovals with estimated contours illustrating what areas of the Earth are most likely to observe low, moderate and/or high levels of auroral activity. - Determine where aurorae can be observed directly overhead. - Learn the behavior of the auroral oval. - Predict possible levels of auroral activity in the future, and determine whether the future activity may be observed from your location. - Determine the equatorward expansion of the auroral oval and how it might affect radio signal paths or auroral visibility. - Simulate the visibility of auroral activity from any ground-level location on the Earth, and for any date and any time. - Determine the characteristics, location, and magnitude of auroral activity for almost any historic period of time or any predicted time in the future. - Plot the locations (ground-stations) where aurorae were sighted for any date from September 1991 to the present, including the major auroral storm period of late March of 1991. - Superimpose any number of great circle paths on the maps the software produces to visually determine their proximity to the auroral oval for any date and any time (highly valuable for HAM operators seeking the best possible radio signal paths). - Superimpose on any of the maps the sunrise/sunset grayline terminator. - Much More . . . This software is based on scientific models, yet does not require any technical knowledge or education to operate. It is ideal for students, teachers, amateur and/or professional astronomers, amateur and/or professional radio operators, the media, and any other individual or group of individuals interested in predicting, observing, or analyzing auroral activity. It requires an IBM or compatible MSDOS computer system with at least 256K of memory and VGA graphics capabilities. The software will use (and benefit from) a math coprocessor if your system is so equipped. Pricing information follows below. Note that all prices are in either Canadian OR U.S. funds. U.S. cheques or money orders are accepted: Spring Special Price: $129.95 <-- Regular price is $149.95. Amateur Astronomy or HAM Ops. : $ 99.95 <-- 23 % discount (see below) Education/Internet Special: $ 94.95 <-- 27 % discount (see below) Persons Registered with the STD: $ 64.95 <-- 50 % discount (see below) (SPECIFY WHETHER YOUR REQUIRE 5.25" OR 3.5" HIGH-DENSITY DISKS) (Canadian Residents please account for GST) (All customers add $5.00 dollars for S/H) (Please allow 2 to 5 weeks for delivery) (ACT NOW WHILE THE INTRODUCTORY PRICES STILL APPLY) Remit all cheques or money orders to the "Solar Terrestrial Dispatch" at the following address: Solar Terrestrial Dispatch P.O. Box 357 Stirling, Alberta, Canada T0K 2E0 People registered with us and seeking the 50% discount price must include their valid registration number with their order. If you have lost your registration number, contact us at: (403) 756-2386. The "Education/Internet Special" only applies to teachers of High Schools, Colleges or Universities, OR to those who have valid electronic INTERNET e-mail addresses. If you are an educator, you must include your educational institutions name and a phone number at that institution where you can be reached. For those who have valid INTERNET e-mail addresses, state your e-mail address(es) to qualify for this 27% discount. If you are a member of a local Amateur Astronomy Club or Amateur Radio Club, OR, if you have a valid amateur radio license, you qualify for the 23% discount. Simply include the name and address (or a phone number for confirmation if an address does not exist) to your club, or your amateur radio call-sign to qualify for this discount. Bulk purchases of the software by Clubs for their members is also possible. Call us for details at (403) 756-2386. All others who do not fall into one of the above categories must pay the Spring Special rate of $129.95 in either Canadian or U.S. funds. All persons who purchase this software are automatically registered with us and therefore qualify for all significant discounts on future software releases or revisions for as long as their registrations remain valid. Prices are subject to change without notice. These Spring Special rates will expire on 31 May, 1993. ** End of Bulletin **
