To: info-hams@ucsd.edu I have a question concerning the new pool of amateur radio questions. With the release of the new no-code technician class license, I've decided it's time for me to go ham. I've got the question and answers for elements 2 and 3A, but they are slightly out-dated (good up to 11/1/89). What are the changes between the old and new questions? Is it safe to study using the old data that I have? How/where could I obtain the new questions? (maybe someone could send me the changes via email?) Please respond or send email.. Steven D.

This activity has spread a bit further south than was originally anticipated. Middle latitude geomagnetic activity became active to very active between 14:00 UT and 18:00 UT. Activity at the present time (18:30 UT) has calmed down somewhat, although periods of active to very active conditions over middle latitudes are expected to continue for the next 24 to 48 hours. There is a risk of brief periods of middle latitude MINOR geomagnetic storming. No major storming will occur. Most of the activity should be below minor storm levels. Magnetic K-indices of 4 and 5 are expected over the middle latitudes. Middle latitude magnetic A-indices could reach 32. High latitudes will experience low to moderate intensity minor storming over the next 24 to 48 hours. K-indices of 5 will be dominant. Isolated brief major storming may occur over some locations with estimated K-indices between 5 and 7. High latitude A-indices could exceed 40. Auroral activity will be most intense over the high latitude auroral zone. Some southward migration of the auroral oval is possible over the next 24 to 48 hours. High latitudes will experience mostly moderate auroral activity with some possible bursts of high activity during substorm periods. Northerly middle latitudes will witness low to moderate auroral activity. Central middle latitudes could witness low activity while southerly middle latitudes and low latitudes will not experience any auroral activity. This could change, however, if major flaring continues. The lower latitude limit for observing auroral activity in the U.S. will range between approximately 42 N for the eastern U.S. to 44 N for the western U.S. during the evening hours. No significant auroral storming is expected, although localized active periods could materialize. Polar and auroral radio paths will experience increased fading and absorption due to the increased geomagnetic and auroral activity which has occurred recently. Auroral flutter will dominate polar and high latitudes, particularly during the local evening hours. High and northerly middle latitude VHF auroral backscatter communications may become possible during the late afternoon hours and again near local midnight. A geomagnetic storm alert will be posted if middle latitude magnetic activity surpasses storm level thresholds. /\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\ ------------------------------ Date: Sun, 10 Mar 1991 03:29:40 -0500 From: oler@HG.ULeth.CA (CARY OLER) Subject: SOLAR TERRESTRIAL BULLETIN - 10 MARCH (SOLAR UPDATE) To: info-hams@ucsd.edu /\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\ SOLAR TERRESTRIAL BULLETIN 10 March, 1991 Updated Solar Activity Information /\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\ UPDATED SOLAR ACTIVITY INFORMATION No major flares occurred on 09 March, although significant spot activity has been observed in Region 6538. This region, which was the source of strong solar activity on 07 March has become slightly more compact. Spots within this region have increased from 63 on 09 March to 107 on 10 March. High levels of shear still appear to exist in this region. Some magnetic complexity is also apparent in this beta-gamma system. Region 6538 is now centered at a location of S23E32 and is now capable of producing moderate to high terrestrial impacts if a significant major solar flare erupts. Proton activity won't be a real threat until after 12 or 13 March. However, geomagnetic and auroral impacts could be high if a strong solar flare erupts anytime between now and approximately 18 or 19 March. Proton impacts will be possible until after this region passes beyond the west limb, which is expected sometime near 20 March. PCA activity will also be possible anytime after about 13 March until near 20 March. A 245 MHz solar radio noise storm was in progress throughout all of 09 March. This noise storm is most likely associated with Region 6538, which has shown some high spot activity recently. Major flaring is still expected to occur from Region 6538. Major M-class flaring is likely to be observed. Isolated major X-class flares are also possible. Minor M-class flaring is a certainty from this region. Flare sizes could still reach a 3B optical rating. Minor to major geomagnetic storming has been observed several times during the UT day on 09 March over high latitudes. Activity increased to major storm levels over the high latitudes at approximately 01:50 UT on 10 March. Activity has since subsided somewhat, although pulses of minor to major magnetic storming is still expected to occur over the high latitude regions over the next 24 hours. Middle latitudes have experienced a couple of brief periods of minor geomagnetic storming. However, overall activity has not yet surpassed storm level thresholds over the middle latitudes. A sudden magnetic impulse was observed over middle latitude magnetic observatories at 22:46 UT on 09 March. The intensity of this SI ranged from approximately 30 to 45 gammas. Low to moderate intensity minor storming was observed over middle latitudes between 01:50 UT and 05:30 UT on 10 March. However, no significant rapid magnetic excursions were observed with this activity. The geomagnetic field over the middle latitudes has declined to generally very active levels. Minor storm periods are still possible (if not expected). Auroral activity increased after 01:30 UT on 10 March. Moderate auroral activity was observed over middle latitude regions. The auroral oval has shifted optically southward. The leading edge of the oval was measured to be at an elevation of approximately 50 degrees above the northern horizon at N49W112. A diffuse auroral arc was the primary activity observed during the observation. No further significant migration of the auroral oval is expected over the next 24 hours. Migration back to the higher latitudes will occur on 11 and 12 March. Overall geomagnetic and auroral activity will subside on 12 March (barring any significant solar activity). HF radio signals have suffered some degradation due to the recent burst of geomagnetic and auroral activity. Areas most heavily affected are the high latitudes and northerly middle latitudes. Radio signal paths which enter or cross through the auroral zone (ex. polar or high latitude paths) have experienced moderate fading and increased absorption. Auroral flutter is very apparant in the high and middle latitude signals. So far, the flutter fading has not been too intense (judging by the reports received so far). VHF auroral backscatter communications may be possible over the northerly middle and high latitude regions. Best opportunities for DX contacts exist using CW. Please report any DX contacts on the VHF bands to "oler@hg.uleth.ca". And again, reports of auroral activity sightings can also be directed to the above address. Thanks, to all those who send in reports. ** End of Bulletin ** ------------------------------ End of Info-Hams Digest ******************************
