At the ES Fox Observatory (established in 2011), we have a large reflecting telescope (a 28-inch Webster) and a 10-inch SCT on a GOTO mount that we use regularly for public viewing. We welcome new members.

New COMET discovered!

Comet C/2018 V1 Macholtz-Fujikawa-Iwamoto
Click on map to download chart below:
Machholz-thru-mid-Nov

Comet C/2018V1 is now 8th magnitude and brightening The comet presently is 20° high at the start of morning twilight above the eastern horizon near the star Porrima in Virgo. It moves away from Porrima in a line eastwards above Venus. The comet is closest to Venus on Nov 18 at only 10° from the -4 magnitude planet and worth getting up before dawn to have a look. At that time, it will be very close (20 minutes or arc) to zeta-Virginis or Heze. Many observers in the US have reported that it is not that difficult to spot, but it has a relatively small coma. It should brighten (to magnitude 5?) as it drops lower in the east and approaches the Sun but it also then becomes lost in the glare by month end and more difficult to see. Rounding the Sun in early December, it will re-appear in the evening sky and perhaps be its brightest there. Comet M-F-I is not predicted to get as bright as Wirtanen but all comets, of course are unpredictable. Read all about the discovery here: S&T Comet M-F-I

Naked Eye/Binocular Astronomy Events
Autumn, 2018
Venus -transition to Morning Star
Venus appears now in the morning sky and during the first few weeks of Nov, it climbs out of the solar glare. By mid-November it is far enough ahead of the Sun to officially become the Morning Star. Mercury, on the other hand stays near the Sun in the west and reaches it farthest point east of the Sun on Nov 6. However, it is about the same elevation as the Sun and difficult to see. Then it starts back sunward, passing behind it in late Nov en-route to becoming a morning object along with Venus. From then until the new year it keeps company with Venus in the morning sky and even skims past Jupiter when it appears in the dawn sky in December.

Two Evening Planets Across the Milky Way for the Fall
-Mars and Saturn

Autumn planet watchers have lost Venus in the west and even Jupiter is getting lost in the twilight glow. Only Saturn and Mars remain in the sky at viewable elevations, and sadly even Saturn will be gone by the end of November. Mars on the other hand will hang in until June of next year as it is moving to the east about as fast as the sky is “moving west” on a daily basis. There will be lots of time to attempt seeing surface features on the planet but on the down side, Mars is shrinking in size as we separate from the Red Planet. In June 2019, when Mars disappears into the solar glow, it is less than 10 arc-seconds across, less than half what it was at opposition.

BAS members observe Venus in daytime near Inferior Conjunction

Venus daytime

BAS members Lorraine, Brett and John made successful attempts to view Venus as it passed through inferior conjunction over the last week of October and into early November. Official IC date was Oct 26 when Venus was about 6° from the Sun but John got an earlier image Oct 10 (Sun to right) and then again Nov 4 (Sun to left) but not at IC itself (cloudy!) Lorraine and Brett were on the lookout as well and Brett spotted it visually Oct 30 and Lorraine got a cell phone image on Oct 30 only 4 days from IC. The Oct 10 and 30 images were taken with cell phone and the Nov 4 image was through a 4 inch refractor. The atmospheric turbulence is evident. The percentages of Venus illuminated are given under the date and even though the Oct 26 illuminated portion of Venus was less than 1% the magnitude of the planet was listed as -4.02 in Starry Night! This would certainly have been visible even though it was so close to the Sun. Unfortunately the next inferior conjunction of Venus which happens in June 2020 is a very close pass of the Sun, 0.5°, and will be unobservable by amateurs. We have to wait to Jan, 2022 when we get a 5° miss of the Sun by Venus which should be visible with ordinary equipment.

From Our Astrophotographers:

Comet 21P/Giacobini-Zinner
Frank Williams sent in this amazing shot of Comet 21P taken during Starfest from his observatory in Allenford. He used his refractor (140 mm Tec) and a Canon 6D camera. Image is a stack of two 3-minute shots of the comet plus 37 one-minute images. He used Pixinsight for the processing. Total exposure time was 43 minutes.

Whirlpool Galaxy!
Local astrophotographer defeats cloudy weather (again)!
m51-11-hours--v3_630K

Frank Williams just keeps churning out the images! I know that each one is a lot of work having dabbled in it myself, but Frank has his workflow organized and keeps amazing us with the results. This image of M51 is possible since its location near the tip of the handle of Ursa Major is pretty much at the zenith right now at midnight and there is little atmospheric turbulence in that direction. In winter, M51 skims the horizon and there is no point in imaging or looking at it then. Do get out now and have a look with whatever telescope you have available.

Frank W. provides the following description:
This image is 11 hours with Canon 6d (modified) and cooled to -9C and a 12” F/8 RC *mallincam branded GSO truss scope (no field flattener) cropped to remove the ragged edges of stacked images. It is ~ 11 hours: 60 images 3 minutes each at ISO 800 and 159 images at 3 minutes ISO 3200 (found that cooled 6d is clean enough to increase the ISO). Calibrated, aligned, stacked and processed in Pixinsight. You can boost the saturation to your liking, but I have tried not to go overboard in processing. Many images of M51 (to my taste) are a bit gaudy.

BTW the [tiny] edge-on galaxy upper right [above the companion] is 230 Million ly away! M51 is only 30 million ly years away….

Auroral Displays

Auroral displays in our area are declining as we have passed solar maximum. There have been periods of "blank Sun" where sunspots have been totally absent for a time. However, at far northern and southern latitudes near the auroral ovals, sometimes magnetic disturbances from the sun produce auroras even without visible sunspots. So if the auroral oval in the graphic below is showing an intense RED, aurora borealis may be visible from your location. The graphic is updated regularly with time indicated at the top in UT so subtract 5 h to get local EST, or 4 h for DST. (Use the appropriate factor for other time zones). For more information click here: NOAA home website.

Current Auroral Oval not available right now
