Several online reports noted a distinct increase in visibility and brightness of the pseudonucleus in the minutes and hours after impact. I wish I had observed at a higher magnification and kept my scope on the comet the previous night. Although I don&#8217;t regret the enjoyment folks got from the Sagittarius beauty-detour.<\/p>\n<p>I&#8217;m glad I made the effort to come out this night though. The comet was definitely easier to find and observe. My first glance at 38X gave the unmistakable impression of a pseudo-nucleus. Further inspection even made it look like a split nucleus. I increased power to 120X and found the newly visible pseudo-nucleus to be 1 to 2 minutes north of a star that was just at the edge of the obvious portion of the coma.<\/p>\n<p>Blurring the focus gave the impression that the comet&#8217;s magnitude was very close to that of the nearby star. So far I haven&#8217;t been able to identify the star with Simbad or VizieR (my skills as an amateur astronomer are not complete). So I&#8217;m not able to make a comparative magnitude estimate.<\/p>\n<p>After sketching the view at 120X, I moved down to 38X for a sketch of the larger field. By the time I returned to 120X 40 minutes later, I was able to discern movement of the comet, and plotted this on the 120X sketch.<\/p>\n<p>Overall, it was very satisfying to see the difference in brightness and appearance of the the pseudo-nucleus since the successful impact with the probe. I&#8217;m glad the great skies at Anderson Mesa made the observation possible in my small scope.<\/p>\n<table width=\"470\" border=\"1\" cellspacing=\"0\" cellpadding-left=\"4\">\n<tbody>\n<tr>\n<td><b>Subject<\/b><\/td>\n<td>Comet 9P\/Tempel 1<\/td>\n<\/tr>\n<tr>\n<td><b>Classification<\/b><\/td>\n<td>Comet<\/td>\n<\/tr>\n<tr>\n<td><b>Position*<\/b><\/td>\n<td>Virgo [RA: 13:40 \/ Dec: -09:58.6]<\/td>\n<\/tr>\n<tr>\n<td><b>Size<\/b><\/td>\n<td>5&#8242; (rough inaccurate estimate)<\/td>\n<\/tr>\n<tr>\n<td><b>Brightness<\/b><\/td>\n<td>Undetermined so far<\/td>\n<\/tr>\n<tr>\n<td><b>Date\/Time<\/b><\/td>\n<td>July 4, 2005 &#8211; 10:00 PM<br \/>\n(July 5, 2005 &#8211; 05:00 UT)<\/td>\n<\/tr>\n<tr>\n<td><b>Observing Loc.<\/b><\/td>\n<td>Anderson Mesa, AZ<\/td>\n<\/tr>\n<tr>\n<td><b>Instrument<\/b><\/td>\n<td>Orion SVP 6LT Reflector (150 mm dia.\/1200 mm F\/L)<\/td>\n<\/tr>\n<tr>\n<td><b>Eyepieces\/Mag.<\/b><\/td>\n<td>32 mm (38X), 10 mm (120X)<\/td>\n<\/tr>\n<tr>\n<td><b>Conditions<\/b><\/td>\n<td>Clear, breezy<\/td>\n<\/tr>\n<tr>\n<td><b>Seeing<\/b><\/td>\n<td>3\/10<\/td>\n<\/tr>\n<tr>\n<td><b>Transparency<\/b><\/td>\n<td>Mag 6.5+ NELM<\/td>\n<\/tr>\n<tr>\n<td><b>*Sources<\/b><\/td>\n<td>Orion&#8217;s The Sky Software<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"excerpt":{"rendered":"<p>009P\/Tempel 1 20050704<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_jetpack_memberships_contains_paid_content":false,"footnotes":""},"categories":[10,45,15],"tags":[],"class_list":["post-128","post","type-post","status-publish","format-standard","hentry","category-comet","category-sg-comet","category-sketch-gallery"],"jetpack_featured_media_url":"","jetpack-related-posts":[{"id":127,"url":"https:\/\/perezmedia.net\/beltofvenus\/2005\/07\/03\/comet_9ptempel_1\/","url_meta":{"origin":128,"position":0},"title":"9P\/Tempel 1 &#8211; July 3, 2005","author":"jperez1690","date":"July 3, 2005","format":false,"excerpt":"009P\/Tempel 1 20050703","rel":"","context":"In &quot;Comet&quot;","block_context":{"text":"Comet","link":"https:\/\/perezmedia.net\/beltofvenus\/category\/comet\/"},"img":{"alt_text":"","src":"","width":0,"height":0},"classes":[]},{"id":17,"url":"https:\/\/perezmedia.net\/beltofvenus\/2004\/08\/01\/comet_sketches\/","url_meta":{"origin":128,"position":1},"title":"Comet Sketches","author":"jperez1690","date":"August 1, 2004","format":false,"excerpt":"Comet Sketches","rel":"","context":"In &quot;Gallery&quot;","block_context":{"text":"Gallery","link":"https:\/\/perezmedia.net\/beltofvenus\/category\/gallery\/"},"img":{"alt_text":"","src":"","width":0,"height":0},"classes":[]},{"id":238,"url":"https:\/\/perezmedia.net\/beltofvenus\/2006\/02\/25\/comet_c2006_a1\/","url_meta":{"origin":128,"position":2},"title":"C\/2006 A1 (Pojmanski) &#8211; February 25, 2006","author":"jperez1690","date":"February 25, 2006","format":false,"excerpt":"C\/2006 A1 Pojmanski 20060225","rel":"","context":"In &quot;Comet&quot;","block_context":{"text":"Comet","link":"https:\/\/perezmedia.net\/beltofvenus\/category\/comet\/"},"img":{"alt_text":"","src":"","width":0,"height":0},"classes":[]},{"id":459,"url":"https:\/\/perezmedia.net\/beltofvenus\/2009\/02\/21\/c2007_n3_lulin_3\/","url_meta":{"origin":128,"position":3},"title":"C\/2007 N3 (Lulin) &#8211; FEB 20, 2009","author":"jperez1690","date":"February 21, 2009","format":false,"excerpt":"C\/2007 N3 (Lulin) 20090220","rel":"","context":"In &quot;Astro Photography&quot;","block_context":{"text":"Astro Photography","link":"https:\/\/perezmedia.net\/beltofvenus\/category\/astro-photography\/"},"img":{"alt_text":"","src":"","width":0,"height":0},"classes":[]},{"id":458,"url":"https:\/\/perezmedia.net\/beltofvenus\/2009\/01\/31\/c2007_n3_lulin_2\/","url_meta":{"origin":128,"position":4},"title":"C\/2007 N3 (Lulin) &#8211; JAN 28, 2009","author":"jperez1690","date":"January 31, 2009","format":false,"excerpt":"C\/2007 N3 (Lulin) 20090128","rel":"","context":"In &quot;Comet&quot;","block_context":{"text":"Comet","link":"https:\/\/perezmedia.net\/beltofvenus\/category\/comet\/"},"img":{"alt_text":"","src":"","width":0,"height":0},"classes":[]},{"id":635,"url":"https:\/\/perezmedia.net\/beltofvenus\/2020\/07\/20\/comet_c2020_f3_3\/","url_meta":{"origin":128,"position":5},"title":"Comet C\/2020 F3 (NEOWISE) &#8211; 18 July 2020","author":"jperez1690","date":"July 20, 2020","format":false,"excerpt":"Sketch of C\/2020 F3 (NEOWISE) - 18 July 2020 Click for larger version.
