Astro-Calendar: 2021 July / Good View of Mercury July 9

       Mercury in true color.jpg

This image shows the planet Mercury as photographed by NASA's Messenger space probe in 2008. Mercury is at inferior conjunction with the Sun on July 1, and the planet cannot be seen even with a telescope. However, Mercury should be easier to find, weather-permitting, on mornings before sunrise, on a few days before and after July 9. On the morning of July 9, Mercury will be at the highest point in the sky just above the southeastern horizon, shining with a brightness of an apparent visual magnitude of +0.3. Early on July 8, Mercury will be just 4 degrees south of the Moon.

I was diagnosed of HERPES virus and i have tried all I can to get cured but all to no avail, until I saw a post in a health forum about a herbalist named Dr Erayo who prepare herbal medications to cure all kind of diseases including HERPES virus. At first I doubted if it was real but decided to give it a try. when I contacted this herbalist via his email and he prepared a HERPES herbal cure and sent it to me via UPS delivery service. when I received this herbal medicine, he gave me steps and directions on how to apply it, after applying the way I was instructed, I was totally cured of this deadly disease called HERPES. All thanks to Dr Erayo for helping me get rid of this virus. Contact the herbal doctor via whatsapp +2348151937428 OR
