Figure 3Figure 1will be 52 degrees away. By clicking on the link in the lower-left corner, I learn that the pathedge nearest to my home in Toronto cuts across southwesternOntario from Port Stanley on Lake Erie to Sarnia on LakeHuron. There is a note that tells me “(t)here are currently 2announced stations for this event” and that none of them ismine. I decide to give it a try. I mark my probable observing siteon the map and a telescope icon pops up marking my station.It also amends the note to three stations and adds that one ismine (Figure 2).Figure 2I click on the link to show station sorts and get a list of allannounced stations, arranged by their relationship to the pathcentreline, path edges, and 1-sigma lines (Figure 3). My stationis good with respect to the other observers. With a few weeksto go, I expect that other occultationists will also sign in, so weshould get a good sampling of this occultation. Now if we couldjust get the weather to cooperate...These are only two of the free programs availablethrough the Web site of the International Occultation TimingAssociation. I highly recommend that you try them. I’m sureyou’ll like them and will agree that everything is up to date atIOTA, if not Kansas City.Here is a list of possible occultations over populated partsof Canada in April and May 2009. For more informationon events in your area, visit the IOTA Web site www.asteroidoccultation.com. Please let me know (emailaddress above) the events in which you plan to participate, sowe can coordinate all observers in the most efficient fashion.DATE (UT) ASTEROID STAR -MAG MAX DUR PATH2009 # NAME MAG (Secs)Apr. 5 5029 Ireland 8.7 7.8 1.6 sON, swBCApr. 8 570 Kythera 10.2 4.9 3.8 NL - QCApr. 8 3617 Eicher 9.5 6.6 2.0 nON - nQCApr. 8 6002 1988 RO 11.5 6.4 4.0 MBApr. 10 1512 Oulu 11.9 3.3 7.1 sBCApr. 15 169 Zelia 11.9 1.3 2.8 NS - nMBApr. 15 366 Vincentina 11.6 2.9 6.0 MBApr. 16 336 Lacadiera 10.3 3.5 11.7 swONApr. 22 186 Celuta 9.8 2.6 5.1 sBCApr. 24 13 Egeria 12.0 0.4 17.0 SKApr. 27 1353 Maartje 11.4 3.1 2.6 sAB - nBCApr. 28 543 Charlotte 11.9 2.7 2.3 NS - QCApr. 30 780 Armenia 12.4 1.9 6.8 swON - nABMay 5 1614 Goldschmidt 8.4 6.8 5.8 sON - nSKMay 5 781 Kartvelia 12.5 2.0 16.9 ABMay 10 467 Laura 10.4 5.3 6.3 sQCMay 11 566 Stereoskopia 10.9 3.6 9.2 NLMay 14 2382 Nonie 10.7 3.8 1.7 nwONMay 17 1786 Raahe 8.9 7.9 3.6 NL - cONApril / avril 2009JRASCCelebrating the International Year of Astronomy (IYA2009)83
