(high value events in large font H3)

2024

late April - Program Plans due Wed May 1. Workshop video instructions

May 2 - last day you can enter grades and positive hours for Astro 27Al

May 3-5 Fri-Sun - Astro 25 at Carrizo Plain National Monument.
May 5 Sun morn at 12:05am - Occultation of R=12.9 Star by Saint-Saens, from our standard Carrizo campsite. Duration = 0.7s Alt=44. RUWE=3.1 so maybe 50/50 chance it'll cross us, but we don't have to make special travel plans. Nicely after students have gone to sleep perhaps. Planning Page

May 6 - STRS on-campus session next to HR.

May 10 3:30-5 NAS DC zoom meeting. See Mar 25 email from Dave R.

May 10 Fri 9pm - Occultation of R=14.5 combined by Trojan asteroid Antilochus, from Pinnacles (sun=-10.8) or MIRA (sun=-10.4). Odds at MIRA are 80%. Centerline odds 90% near Pinnacles. This is one week after Astro 25, but perhaps we could get a van and do an overhighter at MIRA with the Dan and Jean? Alt=30 in west, twilight will be an issue. Planning page.

May 13 Mon 2am - can log into new Schwab acct.

May 17 Fri - tax deadline
May 17 Fri - EFI Sponsored visit: Alice Friedemann on global mineral scarcity for Energy Transformation. 3:30pm CfAO.

May 23 Thur eve 9pm - Occultation of TNO Object 2002XW93, from somewhere in North America. 5% odds of a hit. Sun -9, 13.0 mag, 19s duration.

June 8 - Groveland Grind Mtn bike race near Groveland, CA
June 8 - TrailQuake half marathon in Saratoga

June 25 at 12:05am - Occultation of a 11.6 by NEA Sisyphus, from LA to Las Vegas. High value.

June 27 8am - Occultation of Saturn in daylight. Graze 14N 65+ moon in general Lassen area

Jul 2 - 11am Daylight graze of Atlas (Plieades) from LA area. 16N 12- moon.

Jul 11 - 9pm - Graze of 8.2 star 12N 33+ moon, through Aptos

Jul 13 - 7:30 and 8:46pm Occultation of 1.0 mag Spica on 52+ moon. Photo ops.

Aug 1 - Thur 4:38am - Occultation of a 16.1 (15.4 combined) by Trojan Asteroid Alcathous. from SC, SC Mtns, and MIRA too. High rank, alt=69. ~no moon. Should be do-able in dark conditions with enough integration. May require travel to dark sites, and I will ask about MIRA time. Planning page.

Aug 5 -Tour de Big Bear, part of California Pass Challenge (w/ Mammoth Gran Fondo)

Aug 23 - Fri 1am - Occultation of a 14.9 star by Trojan asteroid (1867) Deiphobus, from xx. alt=69, drop=0.9mag (or 0.5mag because target is a very tight binary with another ~14.7 star so blend could be 13.9->14.5 for 10s max), 82% moon 30 deg away so sky brightness a problem. CabObs 12"? remove f/3.3 to reduce sky? CabObs on 1-sigma line odds=14%. odds=64% on Stockton centerline. Sky brightness is a killer. Probably stay home and try from 12" Cabrillo is best shot. Today is required NAS Fall Division Day. Cannot do big trip anyway.

Aug 30 - Fri 4am - Graze of 5.9 Omega Cancri, from San Juan Bautista area on rising 10- moon on dark limb. Should be a very photogenic opportunity with video.

Sep 13 Fri - deadline for submitting reject/accept retirement incentive for faculty.

Sept 14 Sat morn 2:15am - Occultation of a 10.9 star by binary asteroid Arecibo. Similar path to our Didymus Mojave Desert Amboy trip. But, 78% and 89%+ moon weekend, not good for astro 25. Planning page

Sept 16 Mon 2am - Occultation of 11.1 by Pauly, looks roughly near Pinnacles?
Sept 16 Mon 5:20amm - Occultation of a 10.1 by (51103) 2000HX12 from Sacto area. gradual light curve predicted

Sept 17 Tue 4am - Occultation of Saturn on 99+ moon in dark sky. High power video should look great; 12" scope?

Sept 17 - Partial lunar eclipse at moonrise.

Sept 22 Sunday morn 3am - Plieades Occultation, including Alcyone, and 7.6 mag dark limb graze but nowhere camp-able. Moonrise is just after 10pm which is not acceptable for late night astronomy, so I'll make Astro 25 a week later.

Sept 25 Wed eve 9pm - Occultation of a 11.4 star by NEA Florence, from San Diego to Boulder, NV. High value, bright. Florence has 2 moons of about 0.25km size

Sept 27-29: Astro 25 in the Giant Sequoia National Monument. Astro highlight is the occultation by 2000AP243 of a 12.0 mag star. Sept 28 Sat eve 8pm - Occultation of a 12.0 Star by 2000AP243, from Trail of 100 Giants. Duration 0.7s. IOTA event detail predictions. Red Meadow cmpg is inside northern limit. 22 alt Az=223. Path is 15.5 latitude arcmin wide, and southern limit is north of Kernville, northern limit is south of Quaking Aspen cmpg, but Long Meadow and Red Meadow are well inside the northern limit. moon 9- predawn. Google Earth shows trees at the campgrounds were saved from the fires of years ago.

Oct 5 Sat eve - 10%+ moon 4 deg from Venus which is 0.7 deg from Beta Librae binary, eve sky.

Oct 19 - Mt Diablo Summit Stomp.

Oct 22 - 6:30am - Graze of 5.3 sun=-11, 8N 68- moon (49 Aurigae) from Moss Landing

Oct 25 - Fri 3:55am - Occultation of J=15.0 star by Trojan Asteroid Mentor. Centerline over MIRA with 52% odds, 39% odds from Santa Cruz near northern limit. 39 alt, 7s duration. 39% moon far away. This looks like a good MIRA oppotunity which makes the weekend of Oct 25-27 a bad choice for Astro 25.

Nov 16/17 - Full moon occultation of the Plieades. Weekend.

Nov 19 Tue eve 9pm - Occultation of 11.3 star by NEA Florence, through Santa Cruz. High value, bright. Florence has 2 moons of about 0.25km size. Have to try from Cabrillo Observatory.

2025

Jan 9 - Plieades occultation on gibbous moon at sunset. Graze of a 6.8 star near Davenport sun -6.

Jan 13 - Occultation of bright Mars on full moon. Video opportunity again. at Alt=8 and 17 deg.

Feb 5/6 - midnight area; Plieades occultation on 60+ moon.

Mar 6 Thur eve - Graze of 1.7 mag Beta Tauri from Carrizo area; 5.5n 55%+ moon, alt=62.

Mar 13 thur eve - total lunar eclipse. 9.3 graze through Hayward area 9% after end totality

Mar 22 sat morn 4am graze of 6.1 but 8 deg alt, Sequoia?

Mar 31 Mon eve - graze of 4.7 mag Epsilon Arietis, 1.3" 5.6+5.6 double star, from Hayward area. Probably first day back from Spring Break. Tough.

Apr 15 late eve - Occn of 2.9 mag Pi Scorpii on 90- moon

Apr 18-20 Fri-Sun: Astro 27 at Laguna Mtn. Final meeting May 2 optional for students.
