Meteor Activity Outlook for June 20-26, 2020
Meteor Activity Outlook for June 20-26, 2020 AMS Event #2360-2020, Fireball over Thuringia state, Germany on May 15th, 2020 © M.Tebeck During this period the moon reaches its new phase on Monday June 22nd. At this time, the moon is located near the sun and it invisible at night. As the week progresses the waxing crescent moon will enter the evening sky but will not interfere with meteor observing. The estimated total hourly meteor rates for evening observers this week is near 3 for those viewing from the northern hemisphere and 4 for those located south of the equator. For morning observers, the estimated total hourly rates should be near 11 as seen from mid-northern latitudes (45N) and 15 as seen from tropical southern locations (25S). The actual rates will also depend on factors such as personal light and motion perception, local weather conditions, alertness, and experience in watching meteor activity. Note that the hourly rates listed below are estimates as viewed from dark sky sites away from urban light sources. Observers viewing from urban areas will see less activity as only the brighter meteors will be visible from such locations. The radiant (the area of the sky where meteors appear to shoot from) positions and rates listed below are exact for Saturday night/Sunday morning June 20/21. These positions do not change greatly day to day so the listed coordinates may be used during this entire period. Most star atlases (available at science stores and planetariums) will provide maps with grid lines of the celestial coordinates so that you may find out exactly where these positions are located in the sky. -

You may have noticed that this newsletter is showing up a little bit later than usual, and it’s for good reason: release of the newsletter will now happen after the monthly business meeting so that we can have a chance to keep everybody up to date on the latest information. Sometimes, this will mean the newsletter shows up a couple of days late. But, the upshot is that you’ll now be able to see what we discussed at the recent business meeting and have time to digest it before our general meeting in case you want to give some feedback. Now that we’re on the new format, business meetings (and the oft neglected Light Pollution Committee Meeting), are going to start being open to all members of the club again by simply joining up in the respective chat rooms the Wednesday before the first Monday of the month—which I encourage people to do, especially if you have some ideas you want to see the club put into action. -
Comprehensive Time Series Analysis of the Transiting Extrasolar Planet WASP-33B ,

HD 15082 (WASP-33) is the hottest and fastest rotating star known to harbor a transiting extrasolar planet (WASP-33b). The lack of high precision radial velocity (RV) data stresses the need for precise light curve analysis and gathering further RV data. Aims. By using available photometric and RV data, we perform a blend analysis, compute more accurate system parameters, confine the planetary mass, and, attempt to cast light on the observed transit anomalies. Methods. We combined the original HATNet observations and various followup data to jointly analyze the signal content and extract the transit component and used our RV data to aid the global parameter determination. Results. The blend analysis of the combination of multicolor light curves yields the first independent confirmation of the planetary nature of WASP-33b. We clearly identify three frequency components in the 15–21 d−1 regime with amplitudes 7–5 mmag. These frequencies correspond to the δ Scuti-type pulsation of the host star. -
Lists and Charts of Autostar Named Stars
APPENDIX A Lists and Charts of Autostar Named Stars Table A.I provides a list of named stars that are stored in the Autostar database. Following the list, there are constellation charts which show where the stars are located. The names are in alphabetical orderalong with their Latin designation (see Appendix B for complete list ofconstellations). Names in brackets 0 in the table denote a different spelling to one that is known in the list. The star's co-ordinates are set to the same as accuracy as the Autostar co-ordinates i.e. the RA or Dec 'sec' values are omitted.

The Denver Observer September 2015
The Denver SEPTEMBER 2015 OBSERVER On the evening of the 27th, Coloradoans will get to see a total eclipse of the moon, like the one pictured here. (See story on page 5.)

Stellar Radial-Velocity Programs of the Lick Observatory
STELLAR RADIAL-VELOCITY PROGRAMS OF THE LICK OBSERVATORY George H. Herbig Lick Observatory, University of California The first director of the Lick Observatory, Edward S. Holden, fully recognized the importance of extensive radial-velocity infor- mation for the determination of the motion of the solar system in space. He regarded it as "the main [spectroscopic] research to be undertaken with the great telescope." In 1890, he drew up an extensive program of observations to be carried out visually at the 36-inch refractor by J. E. Keeler. The contribution of Holden to- ward starting radial-velocity work at the Lick Observatory is not generally appreciated. It is true that he played an administrative rather than a participating role, but it was an essential contribu- tion nonetheless. Holden's attitude is indicated by the letter of instruction from him to Keeler, dated September 15, 1890, which reads in part : My dear Mr. Keeler : It is now time to begin the principal spectroscopic work for which the great telescope was designed; namely the observations of the motion of stars in the line of sight for the determination of the motion of the solar system in space. Your observations on the nebulae have shown that you can do this work better than it is done elsewhere . Such a work as this done properly will require several, perhaps many years, and it ought to be thoroughly thought out before it is begun and an adequate programme adopted and adhered to. I have therefore drawn up the following prelimi- nary scheme for you to look over and criticise . -
