I should explain that Ed Anger is sort of a one-man flame war, and in each column is an inflammatory and provocative tirade against somebody or other, rather like Archie Bunker in his prime. A heavy dose of "(-:"'s is called for. ============================================== Ed Anger's column "My America," *Weekly World News*, January 29, 1991 (quoted without permission): WIN A ROCKET RIDE INTO SPACE --ON A RUSSIAN RUST BUCKET! I got madder than a brain surgeon in a stalled golf cart the other day when I read about a wacky new sweepstakes that lets the winner take a trip in space. Space Travel Services Corp. in Houston, Tex., is setting up a phone line that lets you call in to enter, The only catch is that the lucky winner gets to take a rocket ride all right-- in Russia's *Soyuz* spacecraft! Let's face it. Our Russian buddies are broke and everybody knows it. So how in the hell are they keeping their rocket ships in tip-top shape with no money? They ain't, that's how. I'll personally gurantee you this Russkie spacecraft hasn't had a tune-up in 900,000 miles, for Pete's sake. Much less an oil change. And I wouldn't trust the brakes worth a hoot. The windshield wipers are probably falling off and the radiator's held on with baling wire. The day you get yours truly in some Russian rust bucket to take a ride through space is the day my wife Thelma Jean ought to call the men in the white coats! I'll bet the damn thing even needs a paint job, for crying out loud. I'd trust a Soviet spaceship about as far as I'd trust one of those rattletraps those guys call cars. Hey! If you want to go from here to eternity real quick go ahead and get strapped inside one of those Russian tin cans and blast off. Just make sure your life insurance is paid up. Everybody knows those crazy cosmonauts who'll be driving the thing couldn't care less if they ever get back. The Russians are so broke they'll probably use regular rocket gas instead of the premium stuff we use in our space shuttle. And the last people I'd trust to put me in outer space are some broke ex-commie nerds. Even if you did make it all the way to Russia's *Mir* space station, you'll probably find the electric company has shut off the lights in the damn thing 'cause they can't pay their own bills. But if you still want to spend a fun-packed week aboard this Russkie rocket, here's all you have to do. Just call 1-900-258-2MIR to enter at $2.99 a pop. This space vacation outfit claims even couch potatoes can take the ride of a lifetime-- even if they do come back baked. [Accompanied by nice photo of Soyuz takeoff with the caption: "Texas company's wacky contest could put you inside one of these junk-heap rocket ships that the Russians are too broke to maintain."] ============[End quoted article]======== A few comments: Nice of Ed to give the 900 number. Note that it can't be dialed from outside the United States. If you are worried that *Weekly World News* is prime reading matter in the control rooms of the world's largest proton synchrotron, all I can say is that you are justified.

Date: Mon, 21 Jan 91 21:41:11 MST From: std_oler%HG.ULeth.CA@vma.cc.cmu.edu (Cary Oler) Subject: SOLAR TERRESTRIAL FORECAST AND REVIEW X-St-Vmsmail-To: st%"space+@andrew.cmu.edu" --- SOLAR TERRESTRIAL FORECAST AND REVIEW --- January 20 to January 29, 1991 Report Based In-Part from Data Obtained from the Space Environment Services Center Boulder Colorado -------- SOLAR TERRESTRIAL REVIEW FOR 13 JANUARY TO 21 JANUARY. Solar activity this past week ranged from low to high. Activity began the week at low levels. Only C-class flaring was observed during this period with no significant solar events occurring, despite the relatively complex magnetic fields noted in Region 6447 and the large size and number of spots in Region 6444. Near mid-week, a relatively new region (Region 6455) emerged and grew at an explosive rate. The rapid growth of this region was responsible for the production of a major class M6.9/1B Tenflare at 15:02 UT on 17 January. This flare was associated with a strong Type II sweep frequency burst, but was not associated with a Type IV sweep. An interplanetary shock was possible from this flare, but did not materialize. Activity on 18 January through 20 January remained low. However, on 21 January, another major class M6.2/2N flare erupted from Region 6455. But this time, the energetic event was not accompanied by any sweep frequency events. It did, however, produce a strong radio burst of 2100 s.f.u. at 245 MHz. The location of this latter flare was S14W47. No significant terrestrial impacts are currently expected from this flare. Models suggest only a 16% chance that an interplanetary shock will arrive at earth. Some limb-surging has become visible on both the east and west solar limbs. The surging on the west limb is in response to the departure of decaying Region 6444. Surging has recently been observed at several locations over the east solar limb. In particular, areas near latitudes north 10, south 10 and south 24 have exhibited surging. The active regions responsible for this surging is now coming into view. More detail will be visible over the next 24 hours. Geomagnetic activity over the past week has been generally quiet to unsettled. The most active day of the period was on 17 January. Some high latitude magnetic observatories reported some brief minor to major storming. Middle and low latitudes remained quiet to unsettled with some brief periods of active conditions, particularly after 12:00 UT on 17 January. Auroral activity likewise remained mostly dormant over the past week. Activity peaked on 17 January, when moderate auroral activity became visible over most high latitude locations. Activity declined to mostly low levels over middle and low latitudes. HF propagation conditions this week were above normal. Quiet geomagnetic activity early in the week, together with the higher solar indices produced good, stable propagation conditions over most latitudes. The increased geomagnetic activity on 17 January did not significantly alter the propagation conditions over middle and low latitudes. However, high latitudes did experience increased noise, absorption and auroral flutter. Conditions quickly improved and by 19 January, conditions had improved back to above normal for most locations. The two major flares this week produced SID's/SWF's which may have temporarily disrupted communications over sunlit areas of the earth. The last major flare of 21 January did produce a SID/SWF over Sydney, Australia. The event began at 00:18 UT and ended at 00:50 UT on 21 January. VHF propagation conditions were normal this week. The SID of 21 January may have enhanced VHF propagation enough to provide DX conditions over many sunlit areas. Confirmation of a VHF SID enhancement has not yet been received. SHORT TERM SOLAR TERRESTRIAL FORECAST With the rotation of Region 6444 beyond the western limb on 21 January, and the disappearance of Region 6447 behind the west limb on 22 January, solar indices are expected to begin dropping. The appearance of several active regions on the eastern limb will help offset this decline, and may in fact boost solar indices temporarily. However, a general decline is expected to begin later this week as the major centers of activity rotate off the western limb. There is a possibility that Region 6455 could spawn another major flare over the next 72 hours. The risk for major flaring from this region is declining, but is still worthy of note. M-class flaring is likely this week from Region 6455, departing Region 6447, and the emerging regions on the eastern solar limb. Hence, solar activity will likely fluctuate between low and moderate levels this week. Geomagnetic activity is expected to be generally quiet to unsettled throughout the coming week. A slight increase in activity may be observed early in the period, but should decline to mostly quiet to unsettled conditions throughout the remainder of the period. Auroral activity should also remain mostly dormant throughout the coming week. Some sporadic and isolated activity may be noted over higher latitudes, but in general, activity should remain generally dormant over middle and low latitudes. Any activity observed over higher latitudes will likely remain confined to low levels, with possible brief bursts of moderate activity early in the period. HF propagation conditions are expected to be above normal to normal this week. There is a risk for daytime SWF's (short-wave fades). M-class flaring has increased recently and is expected to remain elevated for at least the next two to three days. MUF's may begin to decline somewhat near the latter part of the week as solar indices begin to drop. No significant recurrent geophysical activity is expected this week to hamper attempts at HF DX (barring any significant solar activity). VHF propagation should remain normal throughout this week. There is a moderate possibility for experiencing some sporadic, relatively brief periods of enhanced propagation conditions on the sunlit side of the earth over middle and low latitudes in response to occassional M-class flaring. There are not expected to be any significant auroral backscatter opportunities this week for the VHFer.
